A collection of vector and raster layers was created for the QGIS demo dataset. The vector layers were derived from VMAP0 data. The raster layer is the gtopo30 layer described in item 1). 9) GML layer A polygon type GML layer of the alaska lakes. The vector layer was derived from VMAP0 data. 10) Shape layer with Climate Data. Download GTOPO30 c/c++ function library for free. A collection of portable functions, written in c, (compiles in c++) for using the GTOPO30 digital elevation model (GTOPO30 DEM). Including a comprehensive terminal client, height using bilinear interpolation, create DEM bitmaps, RLE tile combined data. GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer). GTOPO30 was derived from several raster and vector sources of topographic information. For easier distribution, GTOPO30 has been divided into tiles which can be selected from the map shown above.

GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer). The DEM was derived from several raster and vector sources of topographic information. Completed in late , GTOPO30 was developed over a three-year period through a collaborative effort led by . Download free global elevation data developed a global topographic elevation model designated as GTOPO30 at a horizontal resolution of 30 arc-seconds for the.
