  • 1. Opportunities forOpen Spatial Data Bheshem Ramlal, Ph.D. Department of Geomatics Engineering and Land Management The University of the West Indies St. Augustine
  • 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
  • 4. GIS Worth -Global Estimates
  • 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

  • 14. Open Spatial Data: Issues• Lack of Metadata• No Metadata Standards• Lack of Data Sharing Policies• Lack of Accuracy Specifications
  • 15. 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
  • 16. A Role for the DGELMThe UWI has had significant input in GISDevelopment 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
  • 17. 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
  • 18. 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
