Saint Vincent and the Grenadines



This Landslide inventory map was generated by Cees van Westen (ITC) in 2015 for the Charim project.

The land cover map was generated by the British Geological Survey based on Object-Oriented Image Classification using recent high resolution satellite images. Additional thematic information on roads, built-up areas, landfill sites, quarries, airport and oil terminal were added using GIS.

SVG Topographic map

This map was generated using a hillshading map generated from the Digital Elevation Model, which was made from a LiDAR survey. Unfortuantely the original LiDAR data were not available, and the DEM had a missing part in the top of the island, which was subsequently masked using a DEM from SRTM Elevation was also represented in colour, so that the combination of hillshading and elevation gives the best indication of the topography of the country. The available road map was adjusted based on a very high resolution satellite image (Pleiades, with spatial resolution of 2 meters multi spectral and 0.5 meter panchromatic). Screen digitizing was done to map the road and make a road classification. Building information was available for the entire island. Drainage lines were generated from the Digital Elevation Model and through editing. Place names in Grenada were obtained from an existing dataset, and through available maps and Google Earth. Airports, and other landmarks were digitized using the very high resolution images. Quarries were also mapped from these images. The generation of the individual thematic layers was carried out using the ILWIS software. Final map production was carried out using ArcGIS.
