3GIS and Spatial Data
4- GIS is developed to enable
- the use of spatial information
- to support decision-making
- at different scales
- for multiple purposes.
5The Significance of Data?
Spatial Data is further shaped by the
decision-making process to which it is subject

7Problem
- Immature institutional arrangements
- Immature user/provider relationships
- Poor knowledge of data availability
- Difficulties in assessing data quality
- Inconsistent policies on data access and use
- Lack of best practice in the use of technologies
8Spatial Data Challenges
- Majority of spatial data resides in government
- Large volumes and varieties of data
- Existing standards are forever evolving
- Supporting technical services/architecture
missing - Data and info often developed for one target
- Most of issues/needs are local
- Inefficiencies and duplication
- Inaccessible to potential users due to
restrictive and competing policies
9The Driving Force for Change
- Improved delivery of government services, the
spatial element in e-Government - Facilitating industry development
- National security
- Globalisation
- Technology
- Healthy and safe communities
- Sustainable Development objectives.
10Spatial Data Infrastructure
11Spatial Data Infrastructure
- SDI is an initiative necessary for the effective
collection, management, access, delivery and
utilisation of spatial data
- SDI is about facilitating and coordinating the
exchange and sharing of spatial data - SDIs constitute a set of relationships and
partnerships that enable data sharing, update and
integration (start where you are ready to start).

15Human and Community Issues
Communities concerned are expecting to reap
benefits from their investment in SDIs
- It is essential to understand the significance
of human and community issues, as much as
technical issues as they determine the long
running success of an SDI innovation
- Developing a successful SDI must be seen as a
socio-technical and socio-economic rather than a
purely technical exercise.
16Socio-Technical Viewpoint
- Techno-Centric
- Spatial data community
- Focus on technology
- Technology push
- Because its possible
- Others are developing
- Specified by technologist
- Static in nature
- Socio-Technical
- Spatial data community
- People and technology
- Demand driven
- Because its needed
- We need it
- Specified by Users
- Dynamic in nature
(Modified from Petch and Reeve 1999)
17SDI Development Models
- Product-Based Model (linked) database(s)
- Process-Based Model strategy required to manage
information assets
Both models are relevant to National SDIs
depending on the political system of the country
being Federated or non-Federated (centralised).
Non-Federated nations are able to take either
model depending on their national spatial data
strategies.
18Generational Development of SDIs
- For the first generation, data was the key driver
for SDI development and the focus of initiative
development, and - the value of SDIs was measured in terms of their
productive output, the savings for
producers/providers of spatial data, and from
sharing. - However
- For the second generation, the use of that data
(and data applications) and the need of users are
the driving force for SDI development. and - the second generation has a more holistic
understanding of the financial and socio-cultural
benefits of SDI development, as well as support
for spatial decision-making.

23A Strategy for SDI Development
- Increase the awareness and understanding the
vision, concepts, and benefits of SDIs, - Demonstrate the benefits of participation in SDI
to existing and prospective participants, - Develop common solutions for discovery, access,
and use of spatial data in response to the needs
of diverse communities, - Build relationships among organisations to
support the continuing development of SDIs, - Develop a web-based architecture to facilitate
access and to speed the dissemination of data and
services, - Establish the infrastructure and business
practices needed to sustain the changes.
24Collaboration The Key to SDI Development
SDI development is underpinned by organisational
collaboration between levels of governments and
the private sector
(Warnest 2005)
25Collaboration
Understanding the Collaboration Continuum
- Co-ordination
- Few rules
- Limited resources
- Some interdependency
- Agency goals
- Co-operation
- No formal rules
- Minimal resources
- Independent power
- Vague goals
-
- Collaboration
- High degree of formality
- High resource commitment
- Interagency control
- Collective goals
(McDougall et al 2004)
26Key Factors
- Communicate benefits to potential users by short
term projects and demonstrations, - Building the capacity of society, institutions
and individuals, - Long-Term strategic vision and high level
political support, - Include the Marine Environment in the sphere of
SDI initiatives, - Need to understand link between the terrestrial
and marine environments they cannot be treated
isolation, - Understand the sustainable development factors
driving the development of Land-based and Marine
SDIs, - Importance of a lead/coordinate Agency to
- design and implement the SDI concept,
- coordinate the development of standards and
protocols, - building and sustaining foundation data sets,
- providing online public access.
27Key Factors
- Listen to user needs and requirements
- Integrate public and private spatial services
- Team work and data sharing is Key
- Emphasise simplicity and completeness
- Knowledge about the type, location, quality,
ownership of data - Share everything- data, content, infrastructure
- Measure what you want to achieve
- Take action to improve where needed
- Review the whole process periodically

SDI Hierarchy
30SDI Hierarchy and National SDIs
An SDI at a National level has an important role
in building the other levels of SDIs as well as
more relationships with the other levels than any
other level of SDI in the hierarchy.
31Motivation for National SDI Development
- A National SDI ideally should provide benefits
for all stakeholders at the national level - sustainable development,
- national economic development and
cooperation, - national mapping,
- emergency management,
- national security,
- environmental monitoring and
management, - resource management,
- urban and regional planning,
- agricultural and forestry management,
- maritime relationships.

34Australian SDI
The ASDI comprises the people, policies and
technologies necessary to enable the use of
spatially referenced data through all levels of
government, the private and non-profit sectors
and academia (and ultimately the community).
35Australian SDI
- Coordinated by ANZLIC
- Objectives
- To provide fundamental land and geographic
information infrastructure needed to support
economic growth - To provide national standards and guidelines on
the use of geographic data - To maximise community access to spatial
information - To support development of the Australian and New
Zealand spatial information industry - To strengthen the spatial information
organisational framework
36A Value Chain Enabled by the ASDI
DISCOVER tell me what data/services are available
ACCESS give me access to it COMBINE let me
combine it with other inputs USE give it in a
form I can use

39SDI Development and the Role of Private Sector
and Sub-National Government(SDI as an Enabling
Platform)
40Without fully appreciating the role of government
in providing an SDI in a modern society, it is
almost impossible to grasp the potential of SI,
its use by the wider community and opportunities
for the private sector.
41Institutional Arrangements
- Where should the SDI sit in the government
structure? - Convincing government of the importance of SDI
- Role of government, private and academic sectors
- Advisory bodies
- Policies to support data flows in the SDI
hierarchy - Standards
- Custodianship of different data sets

To make spatial information available and useful
to all - at any time and in any place
45Changing Role of SDI
- Starting from the current initiatives to
implement SDI as a mechanism to facilitate
access/sharing of spatial data hosted in
distributed GISs (the conventional concept) - through the access and chain of web services
offered by distributed GISs, making use of
Internet technologies - To a new business paradigm where SDI is
emerging as a virtual jurisdiction or virtual
enterprise to promote the partnership of
SI-organisations (Public/Private) to provide
wider scope of data and services, of size and
complexity that is beyond their individual
capacity. - The development of such SDI requires an
integrated platform to support the chaining of
services across participating SI-organisations.
