![]() ( More info on format for developers).Ī gridfile with "country mask" indicates that the areas outside the selected country are masked out. From DIVA-GIS they can be exported to a number of other grid formats including IDRISI and Arc or to shapefiles. Shapefiles contain a single class of "vector" data such as points, lines, or polygons. It can be imported to most other GIS programs. This is a commonly used format that can be directly used in Arc-anything, DIVA-GIS, and many other programs. Grid (raster) data are stored as DIVA gridfilesĮach "shapefile" consist of at least three actual files. Vector data are stored as ESRI shapefiles ![]() You can use programs such as 7-zip, PKZIP or StuffIt to decompress the files. The files have been compressed and grouped in ZIP files.
