Summary

This theme paper sets out to propose ways in which an enhanced GGDI might be implemented. It does this after re-considering the Coleman and McLaughlin definitions of GGDI and its components and proposing some modest modifications to them. Thereafter it proposes the main, high level practical problems to be resolved; it considers how these have been addressed in national geospatial data use facilitation schemes and how these schemes are relevant to GGDI. The variety of players and the nature of leadership involved, and how the latter can be exercised in implementing GGDI, are then discussed. Finally, a tentative list of actions to ameliorate the problems identified is given, together with resource implications, possible assignments of responsibilities and whether each merits a primarily 'top down' or 'bottom up' approach. It is stressed that conventional management approaches - the identification of Critical Success Factors, etc - will be difficult to apply to GGDI given the disparity of players and their interests but this is no reason for not seeking to improve the current situation.

1. Introduction

This paper is the second of two Theme Papers or discussion documents prepared in advance of an international seminar on Global Geospatial Data Infrastructure to be held in October, 1997 at the University of North Carolina Alumni Centre in Chapel Hill, North Carolina, USA The objectives of this document are to:

The first Theme Paper - dealing with the definition of Global Geospatial Data Infrastructure and identifying regional and global initiatives which could contribute to building such a GGDI - was produced by Dr David Coleman and Dr John McLaughlin of the University of New Brunswick in Canada. Its conclusions serve as the starting point for this paper.

2. Defining the Global Geospatial Data Infrastructure (GGDI) and its components

Before proceeding to implementation issues, it is vital to define both the GGDI itself and its component parts.

2.1 The nature of GGDI according to Coleman and McLaughlin.

We already have a Global Geospatial Data Framework. It is possible to get some data for many parts of the world. Yet - as set out in section 3 - there are many problems associated with the status quo: Mounsey 1991, for instance, has described some of the many problems involved in assembling an environmental database for Europe and the EC (1997) have recognised this in setting plans for the future which have much relevance for GGDI. The GGDI initiative is therefore an attempt to improve the present situation rather than design something in vacuo.

As Coleman and McLaughlin concluded, 'There is understandably no clear agreement on what "(geo-) spatial data infrastructure" and "geographic information infrastructure" efforts should or should not include: both the existing situation and most appropriate implementation strategies will necessarily vary from country to country. However, since development of a global geospatial data infrastructure does involve a common understanding of at least a fundamental set of concepts and terms, it is important to at least introduce for discussion the components and competing visions driving the various infrastructure efforts at this time'.

They assumed the following definition of the component terms:

"Global" implies that anyone, anywhere will eventually be able technically to access non-confidential data about the whole planet and its constituent parts;

Following McKee, they defined "geographic" data as those data describing phenomena directly or indirectly associated with a location and time relative to the surface of the Earth. They opted to use the term "Geospatial" rather than "spatial" or "geographical" in order to be as inclusive as possible;

The word "Data" was chosen in lieu of "information", since the authors of Working Paper 1 envisage an environment in which much of the decision-making with respect to packaging data into information will reside with the user; and

they follow the Webster definition of "Infrastructure" as "...the underlying foundation or basic framework of a system or organisation."

Based on a consideration of the components which they saw comprising the GGDI and this terminology, the authors suggested the following working definition of GGDI:

"A Global Geospatial Data Infrastructure encompasses the policies, technologies, standards and human resources necessary for the effective collection, management, access, delivery and utilisation of geospatial data in a global community."

They pointed out that it would be diplomatically naive, operationally problematic and economically absurd to assume that each of these four elements - policies, technologies, standards and human resources - should be or could ever be the same in every country. For this reason, the clear and growing need for global data coverage to satisfy specific environmental science initiatives will have to be satisfied for the foreseeable future by a patchwork quilt of selected global, national and project-specific datasets.

While truly global infrastructure remains a longer-term goal, Coleman and McLaughlin presented examples of trans-national geospatial data infrastructure (or "TGDI") programmes already underway by government, military and commercial interests. In these cases, the emphasis is placed on establishing application-specific information infrastructure in place on a cross-border, continental or perhaps even inter-continental basis (such as the SABE and PETIT databases for Europe). Given these existing programmes, they raise the question of whether it is possible and worthwhile to collect and integrate the output from these individual TGDI efforts into some larger GGDI.

The Coleman and McLaughlin definition leans heavily upon that used for the US National Spatial Data Infrastructure. Neither contains any explicit reference to the financial resources needed to create or manage geospatial data. The remits of governmental bodies are only present in that they are subsumed by 'policies'. This is not appropriate in many cases: remits were often set many years earlier and may well be unchanged by present policies. To that extent, 'institutional arrangements and remits' are under-represented by the definition adopted. Finally, as proposed, the data are not themselves part of the GGDI - as if roads are not part of the transport infrastructure! It can be argued that the entire focus of the GGDI should be on facilitating use of geospatial data. Thus an alternative definition of the GGDI would be:

"A Global Geospatial Data Infrastructure encompasses the policies, organisational remits, data, technologies, standards, delivery mechanisms and financial and human resources necessary to ensure that those working at the global or regional scale are not impeded in meeting their objectives"

Account will be taken of these points in the rest of this paper. Since it is a wider definition in some respects than that adopted by Coleman and McLaughlin, all their concerns can be subsumed within it.

2.2 The GGDI stakeholder communities

Coleman and McLaughlin saw these as comprising:

In a later section, they made it clear that data providers (such as National Mapping Organisations or NMOs) and newly emergent private sector data suppliers also had a strong actual or potential interest in the GGDI. It is arguable that the citizenry also have a stake in GGDI, both directly (as potential users of some data) and indirectly (since the data will in one sense be deployed by these groups on the citizens' behalf). Certainly however the international development community have a strong interest in the GGDI (see, for instance, Htun 1997 and Estes et al 1995). Clearly there is some overlap between membership of these stakeholder communities.

2.3 Different perspectives on GGDI

As Coleman and McLaughlin also pointed out, it is possible to view GGDI from a number of alternative perspectives. They saw these as:

In turn this demands some consideration of the players in GGDI and their agendas for it is unlikely that these will be coincident. Table 1 suggests what some of these agendas might be; failure to recognise these different agendas at the outset will cause much misunderstanding later. This is discussed further in section 5.2.

It is self-evident that there will be complex interactions between and within many of the GGDI components - policy clearly interacts with technology (and finance!). The interactions are too numerous to list and in any case may be very particular to the local domain and change periodically. As one example, however, Rhind (1996) has cited ten of the institutional and policy factors impacting on availability and pricing of data for his own organisation (see table 2); there are many other factors, including the cost of hardware and software and its performance.

2.4 Open questions

Finally Coleman and McLaughlin have pointed out that criticisms of 'information infrastructure' - in fact, of the overall global information society vision - have emerged from a wide variety of quarters, and from both developed and developing communities. Given this, they raise various questions for consideration by Conference participants:

It will be obvious that the answers to these questions have major potential impacts on the conclusions of this paper!

3. The practical problems to be resolved

The situation in relation to data and the components of GGDI previously discussed earlier can be summarised as:

4. Implementation of national data infrastructures or frameworks

It is impossible to ignore what has already been achieved and what is in progress in various countries. There are two reasons for this:

Annex 2 describes two such schemes which have some significant similarities but also some considerable differences. The latter arise from different cultural contexts and other factors. These differences are difficult to pin down with precision- since many deal with 'soft issues' and the situation is constantly evolving - but are summarised at the end of annex 2.

What is common to such schemes is the need to find incentivisation mechanisms to persuade people to collaborate. This is most easily done through money but, in the absence of that, enlightened self-interest and altruism may be the only mechanisms. It is rare that this will achieve coherent, consistent and readily useable results. In addition, tangible progress is essential: the substantial resources dedicated to definition of standards over many years which resulted in unused de jure standards is well-known and to be avoided if possible. The role of commercial sector interests is one which seems likely to gain much greater importance in many national data facilitation schemes - with all the difficulties this creates given the different agendas of commerce, governments and other bodies.

5. Who is in charge? Who are the players?

Technology is a necessary but far from sufficient condition for success in meeting GGDI objectives. The people, institutional and financial issues are liable to be much more significant determinants of success.

5.1 Who is in charge of GGDI?

The essence of national data use facilitation schemes such as NSDI or NGDF is that no one body is 'in charge'. Indeed, any attempt to take charge is typically regarded as a resurrection of old-style organisational politics and unpaid collaboration tends to diminish. This situation is even more the case in an international domain.

How then is leadership deployed, strategic direction forged and action achieved? This is normally achieved in the first instance by a small number of key players coming together with an idea and formulating it in a way which has attractions for themselves and for others. It helps enormously if these players already have considerable respect in the community and if they command resources in terms of cash, manpower or influence. The important assets in this regard are physical, human, social and intellectual capital (Htun 1997)

For success, there needs to be some acceptance that breadth of coverage of communities is important and some evidence that those concerned can speak in a representational sense for the communities. Simple assertion that 'I will speak for community x' is inadequate if these wider communities are to be carried.

The danger is of course that very large numbers of individuals and organisations become involved so some way of involving these parties other than through traditional meetings is required. The norm is to have some hierarchical structures. The OGC provides an interesting example of how to cope with the growing pains of a multi-national grouping. The Greek city state alternative - of letting everyone take part through email discussions and contribute what they can - is feasible and may even be desirable for some purposes but it is unlikely to effect global data infrastructures which have any pan-national consistency.

So far as GGDI is concerned, the situation is proto-embryonic. The existing group is self-selected and, whilst it includes highly expert individuals, can scarcely claim to represent communities in a formal way. Only a few sizeable organisations are involved, with the science and commercial sectors notably under-represented at the initial Bonn meeting. It should be noted that these organisations are already responsible for spending billions of dollars annually on data collection, validation, calibration and use. Proposals for improving the situation are set out in section 6.

5.2 The actors involved and their roles

It is self-evident that many players are actually or potentially involved in a GGDI. These include (in no priority order):

It is also self-evident that not all of the players will have the same agendas. Table 1 suggests some likely motivations and agendas of a selection of these players. This disparity of view needs to be factored into any actions.

6. Some practical steps which could be taken

It is conjectured that we should be seeking to build a framework to facilitate and encourage efficient linking, combining and widespread use of geospatial data i.e. to:

Two possible approaches suggest themselves for advancing the cause of a GGDI and improving the present internationally incoherent and inefficient situation. Both may usefully be employed. These are the:

It is contended that we have little choice but to exploit both of these apparently disparate approaches. Both are potentially powerful agents of change. Table 3 sets out a detailed set of proposals for actions based on the definitions of the problems given in section 3, the definitions of GGDI, stakeholders, etc summarised in annex 1 and acceptance of working both 'bottom up' and 'top down'.

Items which have not specifically been covered in this discussion include the cultural, security and pricing ones so far as data availability are concerned. Cultural differences - both in the data collected nationally, the use which is permitted and the nature of international collaborations are likely to be of considerable importance. How to assess or anticipate these is left as an open question. Security matters remain a matter of great significance for many nations, especially as high resolution sources of data are concerned: beyond the basic topography, information such as sources of good quality water can become tactically significant. No simple, single answer can be expected to availability of such data on a global basis; on the contrary, the matter may well have to be a very local one even though there has been a gradual trend towards greater open-ness in the last decade. Finally, the cost of accessing data is a matter of great importance for some users and some providers alike. This is likely to be an ever-greater problem as private sector providers become more numerous and as many governments (such as those in the Nordic countries, Canada, Australia, New Zealand, France, Russia, the UK and elsewhere) seek to implement partial or total 'user pays' (c.f. 'taxpayer pays' policies. Whether there is anything meaningful that GGDI players can agree on in regard to such policies and practices is debatable.

Table 3 of proposed implementation actions for GGDI is presented as a basis for discussion. Implementation of GGDI can only be achieved through multiple different actions carried out by many different bodies, some of whom are normally in competition. It follows that GGDI can not conceivably be treated as a simple management exercise; it will inevitably be 'messy' and measuring its success will be difficult and long-term. Indeed, any successes may well owe much to other players - notably those forcing the technological pace. That is not a reason for inaction. The globalisation of the world economy and its implications for government and the citizen alike suggest there is merit in progressing GGDI.

Table 2 The 'cocktail' of laws, policies, conventions and precedents which influence the availability and price of geospatial data for Ordnance Survey in Britain:

the UK government's commitment to open-ness, as set out in the 1994 Code of Practice for Access to Government Information (but note paragraph 4 which says there is no requirement on departments to change the basis on which they provide information if it is already made available on a charged basis)

the government's agreement to international protocols (such as Agenda 21)

the government's Tradable Information Initiative of 1986 (with revised guidelines published in 1990), led by the Department of Trade and Industry which encouraged government departments to make available their information holdings at a market price

European Directives translated into British law (such as Directive 90/313/EEC on Access to Environmental Information and Directive 93/98/EEC on harmonisation of the duration of protection and the legal protection of databases)

individual decisions taken by different government departments or Executive Agencies in pursuit of their mission or to generate revenue to support the cost of their services to the public. Thus OS Northern Ireland has a different charging regime to that of OS, instituted with the objective of increasing its cost recovery from around the current level of about 30% to one closer to the OSGB level of around 90%.

individual product-level decisions made by government departments or Executive Agencies to maximise their revenue generation. Thus the differing price elasticity of different products may lead to very distinct pricing policies even within one Agency, extending perhaps as far as geographically differentiated pricing.

bi-lateral agreements between government departments (e.g. between the Ministry of Defence and other map-making organisations)

bi- or multi-lateral agreements made by departments with their counterparts overseas

legal issues pertaining to Intellectual Property Rights, fair trading, legal liability and to parliamentary statutes. Each of these issues is complex; their interactions are sometimes highly complex.

Annex 1

Summary of components of GGDI, amended after Coleman and McLaughlin

A1.1 Revised definition of the GGDI

As used in this paper it is:

"A Global Geospatial Data Infrastructure encompasses the policies, organisational remits, data, technologies, standards, delivery mechanisms and financial and human resources necessary to ensure that those working at the global or regional scale are not impeded in their objectives"

A1.2 The GGDI stakeholder communities

These are:

Annex 2

Implementation of national data policies and data infrastructures in the USA and UK

Information policies differ greatly in different countries and even within a number of countries. Masser (1998) and Rhind (1998) have described some of these variations and the consequences they produce. Here we examine only two national situations, using them to illustrate general points.

A2.1.1 Information policy in the USA

The US federal government sees distribution of data it holds at the cost of dissemination (or less) as a matter of principle. This has most recently been set out in the Office of Management and Budget's Circular A-130 (the latter now having been codified as section 3506(d) of The Paperwork Reduction Act 1995) in codifying this principle.

Circular 130 (OMB 1993) states that 'The free flow of information between the government and the public is essential in a democratic society.' It also states that charges should be set at 'a level sufficient to recover the cost of dissemination but no higher'. Section 105 of the US 1976 Copyright Act specifies that copyright protection is not available for any work of the US government that is prepared by an employee or officer of the government as part of that person's specific duties.

Thus federal government is not generally able to assert copyrights and any other party is free to copy, disseminate, license or sell data held by the federal government at will and without seeking permission or notifying the originators of the uses to which it will be put. There are however some potentially important exceptions to this rule. For example, where material has been supplied by foreign governments under specific agreements permitting internal business use (e.g. of data for military purposes), this information may not be passed on and copyright remains with the supplier.

The consequences of this situation are multiple and, in some cases, quite subtle. It has facilitated extensive use of the Internet for data dissemination which in turn has both increased access to the federal geospatial data and shifted some costs of data acquisition to the end-user. However, the great bulk of financing for data collection in the US federal government necessarily arises from appropriations in Congress and the level and use of these line-budget funds are subject to short-term political expediency. In addition, the limited ability to protect information made available by others (especially commercial and some state governments), has made some inter-sectoral data sharing co-operations impossible or highly tortuous.

The situation in state and local governments varies considerably. Though many states have statutes enabling public free or low-cost access to certain types of records, there are at least twenty cases where states had or were in the process of amending these statutes to permit cost recovery through higher levels of charging. Masser (1997) provides a summary of various other studies on state and local government approaches.

Finally, given the strong US pressure to codify and enforce international copyright laws, it is no surprise that the US commercial sector strongly asserts its copyright on most occasions.

A2.1.2 Information policy in the UK

As indicated in various parts of this chapter, the information policy situation in the UK varies not by geography (as in some other countries) but rather by government department (as in the Netherlands, according to Masser 1997). Coopers and Lybrand (1996) summarised the variability in policy and practice in the UK and table 1 illustrates the financial part of it. This variability arises from the different remits and targets given to government bodies - especially the Executive Agencies (which have significant freedoms to decide how to achieve these ends) - by Ministers. Information policy is thus generally a second order matter driven by the need to meet explicit public targets for quality of service, efficiency and financial performance. All government-generated information is regarded as Crown Copyright and its use is licensed though the level of charging may be zero. Some Executive Agencies have delegation of responsibility for administering Crown Copyright whilst others follow central direction.

As in any other system, this has advantages and disadvantages to different organisations or individuals. Certainly the level of use of digital geospatial data in the UK has expanded very greatly in the last five years; much of this however has been in major organisations and a slower take-up has occurred in smaller organisations. The extent to which this reflects data pricing or the nature of society and availability of computing resources is unclear (and it is in any case changing quite rapidly).

A2.2 Unlocking information: the advent of national data use facilitation schemes

There is a growing tendency world-wide to seek greater value for money in relation to geospatial data or GI. There are many commonalities in these schemes, including the minimisation of duplication where the taxpayer is responsible for funding, the fostering of awareness of what already exists and the encouragement of greater harmonisation in data characteristics. None of this is recent. For example, co-ordination work at both national and state level in Australia and New Zealand long pre-dates recent initiatives. But the first national data use facilitation scheme advertised as such, thought through on a grand scale and promoted heavily was the US National Spatial Data Infrastructure; others have since followed (see Masser 1997, Mooney and Grant 1997). It is therefore necessary to summarise this before making contrasts with other schemes.

A2.2.1 The US National Spatial Data Infrastructure (NSDI)

The bulk of this section is drawn from a summary of the history of the NSDI by Tosta (1997). During the early 1990's, the Mapping Science Committee (MSC) of the United States National Research Council began to investigate the research responsibilities and the future of the National Mapping Division (NMD) of the US Geological Survey. The MSC coined the phrase 'National Spatial Data Infrastructure' and identified it as the comprehensive and co-ordinated environment for the production, management, dissemination, and use of geospatial data. The NSDI was conceived to be the totality of the policies, technology, institutions, data and individuals that were producing and using geospatial data within the United States. The MSC (1993) report proposed a number of actions and responsibilities for various agencies and for the Federal Geographic Data Committee (FGDC) which related to their vision of the NSDI whilst another report a year later urged the use of partnerships in creating the NSDI (MSC 1994).

The FGDC adopted the term NSDI to describe a 'national digital spatial information resource' and discussed the concept of the NSDI with the Clinton Administration teams which were exploring means to 'reinvent' the Federal Government in early 1993. The NSDI was recognised as an idea and a means to foster better intergovernmental relations, to empower State and local governments in the development of geospatial data sets and to improve the performance of the Federal Government. In September 1993, the NSDI was listed as one of the National Performance Review (NPR) initiatives to reinvent Federal Government. Vice-President Gore stated that '(I)n partnership with State and local governments and private companies we will create a National Spatial Data Infrastructure' (Gore 1993).

One of the primary means of implementing the initiatives arising from the National Performance Review was through Presidential Executive Orders. In April 1994, Executive Order #12906: 'Co-ordinating Geographic Data Acquisition and Access: The National Spatial Data Infrastructure' was signed by President Clinton, directing that federal agencies carry out certain tasks to implement the NSDI. These tasks were similar to those that had been outlined by the FGDC in its Strategic Plan a month earlier and since up-dated (FGDC 1997). The Executive Order created an environment within which new partnerships were not only encouraged, but required. In the US, Presidential Executive Orders are only applicable to federal agencies but, in this case, these agencies were directed to find partners (specifically among other levels of government). In practice, according to Tosta (1997), state and local governments will often voluntarily co-operate with federal agencies if this makes it likely to result in funding or improve their access to data. In addition, the Executive Order had significant effects in increasing the level of awareness about the value, use and management of geospatial data among federal agencies specifically. Perhaps more importantly, it raised the political visibility of geospatial data collection, management and use nationally and internationally.

The NSDI is defined in the Presidential Executive Order as 'the technology, policies, standards, and human resources necessary to acquire, process, store, distribute, and improve utilisation of geospatial data' (Clinton, 1994). That Order and the FGDC identified three primary areas to promote development of the NSDI. The first activity area is the development of standards, the second improvement of access to and sharing of data by developing the National Geospatial Data Clearinghouse, and the third is the development of the National Digital Geospatial Data Framework. All of these efforts were to be carried out through partnerships among federal, state and local agencies, the private and academic sectors, and non-profit organisations. So far as standards are concerned, work began in 1996 to refine the initial FGDC metadata standard in conjunction with the International Standards Organisation. As of mid-1997, eleven different thematic standards were in development by FGDC committees with those on cadastral data and classification of wetlands being endorsed. The NSDI Executive Order mandated that federal agencies use all FGDC-adopted standards. A data 'clearing house' is operational: nearly all federal agencies, as well as most States and numerous local jurisdictions, have become active users of the Internet for disseminating geospatial data. This model does not necessarily assume that data will be distributed for free; obtaining some of these data sets requires the payment of a fee, others are free. Finally, various pilot projects investigating different ways of building the framework were launched in 1996 (FGDC 1997)

In its short lifetime, NSDI has generated huge levels of interest in the USA and beyond (see, for instance, Masser 1997). Some considerable successes have been achieved, notably in the formulation of some standards and the creation of the 'clearing house' of metadata. Perhaps its greatest success however has been as a catalyst, acting as a policy focus, publicising the importance of geospatial data and focusing attention on the benefits of collaboration - especially important in a country as large and governmentally complex as the USA. The process of involving many parties continues on several fronts; the MSC, for instance, has attempted to anticipate the most significant GIS developments to society in the period up to 2010 through a large and heterogeneous group drawn from many backgrounds (MSC 1997).

Inevitably, many problems have arisen in NSDI, notably about incentivising different organisations to work together and in ensuring that benefits arise for all organisations incurring costs. The level of direct involvement of the private sector seems small compared to that of the federal government and even that of the states. Moreover, the concept of 'bottom up' aggregation of data to form national data sets now being explored is also an intrinsically complex one since the logistics alone of drawing together data from many thousands of other organisations (e.g. US counties) - which vary greatly in resources and inclinations - is daunting. That said, NSDI has been and remains a considerable achievement (http://www.fgdc.gov/nsdi2.html) and has triggered equivalents elsewhere, including multi-national collaborations, such as the Permanent Committee on GIS for Asia and the Pacific (Majid 1997).

A2.2.2 The UK National Geospatial Data Framework (NGDF)

There has been a long history in Britain of formal consideration of geographic information policies and problems. Examples of this include the Serpell Report of 1979, the House of Lords Select Committee on Science and Technology Report of 1984 (Rhind 1986) and the Chorley Report of 1987 (DoE 1987, Rhind and Mounsey 1989). Indeed, the Davidson Report of 1938 might even be considered as a far-sighted pre-cursor given its emphasis upon the need for nationally homogeneous, readily available, metrically-based data conforming to certain standards. Most of these studies - all of which have had some beneficial effect on the GI industry - have been heavily centred on government as a provider and user of data; the sequence of studies cited however has shown a progression to wider and wider considerations, starting with a focus on Ordnance Survey and spreading in later reports to a wide range of geospatial data.

By the early 1990s however it was becoming clear that the growth of the private sector as supplier of GI services, data and tools, the changing technology and the change in user expectations and needs were creating a quite different situation. No single coherent framework existed in which to consider, influence or organise all the changes. In 1995, recognition of this shortcoming and observation of the progress, achievements and problems of the US National Spatial Data Infrastructure (NSDI) led to what became the National Geospatial Data Framework(NGDF: see Nanson et al 1995).

NGDF was no slavish copy of NSDI. It was recognised from the outset that the situation in the UK differed from that in the USA in many ways, notably the structure and role of government is very different, there is already greater availability of high quality geospatial data across the whole (much smaller) country and government policy is very different with regard to dissemination of information.

The nature of NGDF

In 1995, the problems to be resolved in the UK were (and still are) seen as:

As a result, the NGDF has a mission 'to develop an over-arching UK framework to facilitate and encourage efficient linking, combining and widespread use of geospatial data which is fit for purpose'. The objectives of NGDF are to:

Achievement of these objectives is built upon the three NGDF 'pillars'. These are:

Collaboration, developed through:

Use of standards

Data linkage is the key to creating added value and generating new GIS applications. But world-wide experiences demonstrate that it is easy to create meaningless data sets at great expense by this means: results may be totally erroneous and misleading unless the data sets are well-documented, adhere to agreed and published standards and the likely effects of mixing two data sets have been adequately researched. NGDF will therefore set a framework for defining business driven standards, best practice and specifications for data and services, drawing on existing national, European and international work.

Access

The simplified NGDF model is shown in figure 1. NLIS is the National Land Information Service, a prototype land conveyancing service for England and Wales now in pilot form and involving data inputs from HM Land Registry, Ordnance Survey, local governments and up to about 10 other sources. ScotLIS is the Scottish equivalent. This figure emphasises the crucial point: NGDF is not a service and is not designed to generate revenue: it is a framework within which a variety of services should operate, many of them revenue-generating. As it is inevitable that other services will grow up - indeed, that is to be desired and can not be prevented - the objective is to ensure these take advantage of experience gained in earlier services and are 'NGDF-compliant' so as to future proof any subsequently desired interactions between the services. Many of these services may well be operated by private sector organisations, sometimes in partnership with public sector bodies. It is central to NGDF's success that it will encourage the development of 'many-to-many' relationships between data suppliers, data brokers and consumers.

Making NGDF Happen

NGDF operates through a structure shown in figure 2. The Board consists of (mainly) public and private sector information suppliers and it is advised by a Council representing the end user, the software industry, academic and other interests. This Advisory Council is based in the Association for Geographic Information, the British GI 'umbrella body'. Its members were chosen by election from the AGI membership constituency although spare 'slots' were set up for representatives of other interests who were found to be appropriate but who were not formally members of the AGI. The chair of the AGI acts as the chair of the Advisory Council and has an 'as-of-right' membership of the NGDF Board. Secretariats of the two organisations attend each other's meetings as observers. Table 2 shows the initial membership organisations supplying members to the Board or the Council, the latter representing a wider constituency than their own organisation.

The work of the NGDF is largely accomplished through the Task Force and Working Groups. Membership of the latter is open, within very wide limits, to all who wish to make a contribution. The Task Force is specifically responsible for implementing the NGDF work programme, all elements of which have a timetable and milestones to completion. The Task Force is run by a Programme Director and consists of the convenors of (currently) seven NGDF working groups. These working groups are:

  1. NGDF Programme Definition
  2. Metadata
  3. Research
  4. Development of Best Practice Guidelines (using the implementation of the Environment Act Part II A as a worked example though it is very relevant to NGDF in its own right)
  5. Education and Promotions
  6. Accreditation and Standards
  7. Data Availability and New Requirements
  8. The UK Standard Geographic Base

Areas under development include:

Under the present programme, the currently sought NGDF deliverables include:

A2.2.3 Similarities and differences between the US and UK approaches

There are many similarities at a high level between the US and UK approaches to fostering greater beneficial use of geospatial data or GI. This is not surprising since the latter took account of developments in the former but both reflect some more generally-felt needs to improve the operation of the public sector and to get better value for money expended.

There are also however a number of important differences of emphasis. These derive from a number of sources, including the physical, cultural and political geographies of the two countries, and can be summarised as:
