2. Presentation Overview
• Introduction
• Spatial Data Development in Trinidad and
Tobago
• Open Spatial Data Access – Issues and
Prospects
• UWI’s role
• Conclusions
3. Introduction
• From its initial development in Canada in the
1960s, GIS has grown significantly to become
pervasive in almost all societies
• Globally, spatial data development is a multi-
billion dollar industry
5. Introduction
• With changes in ICT, spatial data have
become much more accessible to
users
• Initially most spatial data were not
accessible to the public.
• There has been a gradual move by
many countries from cost-recovery
policies to open access policies
• Move to develop the public
commons for Geospatial Data

19. Open Spatial Data: Issues
• Lack of Metadata
• No Metadata Standards
• Lack of Data Sharing Policies
• Lack of Accuracy Specifications
20. Open Spatial Data: Prospects
• Significant effort being made to develop
Enterprise GIS by government agencies
• Government moving towards the
development of national policy on Spatial
Data Infrastructure
• Technology becoming more available for the
sharing of spatial data in Trinidad and
Tobago
21. A Role for the DGELM
The UWI has had significant input in GIS
Development in Trinidad and Tobago
– The UWI has designed and delivered over
60 training courses in GIS to industry in the
last 15 years
– Certificate in GIS and a MSc Geo-
informatics programs delivered by UWI
– Provided consulting services for the design
and development of several enterprise
GIS for Government and Private
Sector organizations
– Set up the GIS Society of Trinidad
and Tobago
22. A Role for the DGELM
• Provide support and advice to stakeholder
with respect to policies, standards, and
technical requirements
• Conduct relevant research and develop
appropriate solutions
• Develop and make available spatial data
sets where possible
• Advocate for policy changes
• Support training needs of
stakeholders
23. Conclusions
• While extensive work has been done in the
development of spatial data sets most are not
available for open access to the public
• There is some movement by government
towards setting up a NSDI but this is still at a
very early stage of development
• There is much work to be done to convince
government to adopt open access policies
• The UWI has played a significant role in
making spatial data openly available
