  1. GISas an informer for critical decision making By Jose’ C B de Castro Department of Disaster Management , BVI

  2. GIS- Geographic Information System • “Layers of information about a place” www.gis.com

  3. Hardware and Software Needs • Hardware • PCs/Macs • Server • GPS • Handheld • Digitizer • Software • ESRI—industry standard Arcview • Other manufacturers

  4. The System • Collect Info • Feed info to central database • Info at your finger tips • All decisions should be advised by central database • Inform public and private developments • Result: “Sustainable Development” • Continuous updating and input of new data

  5. 1st step—Collect Info • Two Parts • First establish an accurate base • Lower layers of information • Info later collected are overlaid on base • Set the protocols for how info is collected, stored and used • Also collect associated metadata—cataloging • use Intl standards • Crucial in sharing info

  6. Base maps & Assoc. data • Contours • Ht above sea level • Roads • Road Names • Start and End points • Coastal Resources • Mangroves • Coral Reefs • Other costal organisms • Cadastral • Ownership • Land use/Zoning • Size (Acreage) • Buildings • Building Use • No. of Floors

  7. Metadata—Catalogue • A Separate database that describes the data • Some metadata fields: • Title • Creator • Description • Date of data • Coverage • Format • Degree of accuracy • Source

  8. Who should collect the data? • All stakeholders should collect and share all data • Some data is “confidential” • eg. Turtle Nesting Sites

  9. What data should to be collected? • As much data should be inputted and cataloged according to standards set • Each department must prioritize the input of data

  10. Examples of datasets • Department of Disaster Management • Hazard maps • Disasters • Critical Facilities • Emergency Shelters • Survey Dept • Cadastre • Conservation & Fisheries • Coastal Resources • Oil Spills

  11. Examples cont’d • Police • Crime sites—by type • Criminals’ residence • Fire & Rescue • Instances of Fire—by type • Non-fire calls—by type • Health • Potential Health risks • Sites of outbreaks • Hazardous material locations • Businesses that require a health certificate for operations

  12. Where should the data be stored? • The central GIS database and associated meta-database should be on a remote dedicated server • The BVI has a National GIS Committee • The NGIS committee guides the growth and development of the Govt’s GIS • Each dept, however, is responsible for maintain ace of their data sets

  13. How should the data be used? • Analysis • What critical facilities are at risk to natural hazards? • Where were most of the burglaries last month? • How much forest is in each watershed? • How many oil spills occurs in a specific area per year • How have the coastal resources changed over the last ten years? • Which schools are within 500 feet of a liquor store?

  14. Typical Analysis Map This map shows the potential acoustical impacts on the surrounding area of a particular type of rocket engine.
