The Global GIS Data Bundle contains:
- A set of 506 US military 1:500,000 scale TPCs (Tactical Pilotage Charts–scanned topographic/aeronautical maps), GeoTiff file format, Geo WGS84 (a small number of far-North sheets are natively Polar Stereographic)
- SRTM (Shuttle Radar Topography Mission) 3 arc second (approx. 90m) DEM (Digital Elevation Model), covers the World from Latitude 57 South – 61 North, .bil file format, Geo WGS84 (also includes hydrology vectors used for editing of the DEM data)
- SRTM 30 arc second (approx. 1km) global DEM made from SRTM and GTOPO30
- Landsat 7 ETM 15m 7-4-2 GeoCover 2000 (1999 – 2003) worldwide satellite imagery, MrSID wavelett compressed file format, UTM WGS84
- Landsat 4/5 TM 30m 7-4-2 GeoCover 1990 (1988 – 1992) near-worldwide worldwide satellite imagery, MrSID wavelett compressed file format, UTM WGS84
- VMAP0 worldwide 1:1,000,000 scale vector data (near-worldwide coverage, varies by layer), ESRI .shp and MapInfo .TAB file formats, Geo WGS84.
This is the update of the DCW.
- World Vector Shoreline Plus 1:250,000 scale vector data of the World’s coastlines and international borders boundaries, ESRI .shp file format, Geo WGS84
These sets are not in their raw form and have been converted to SHP or other formats that can readily be used in ArcView and other common GIS programs. All datasets include .shp indexes except VMAP0 and WVS, which aren’t tiled, and SRTM30 which is organized by large lat / long blocks.
