I have a shapefile that is composed of multiple overlapping polygons that represent extent of habitats of certain species. Here is a 1 MB example of such file from International Union for the Conservation of Nature website. I would like to convert the shapefile into multiple GeoTIFFs such that each file contains range map of a single species. How can I do that?
In ArcGIS Info I tried "polygon to raster", but the resulting raster is composed of a single band and multiple values (so that pixel values range from 0 to N, where N is number of species). This way information about overlap is lost. If I could convert my shapefile to multiband (such that each band represents a single species), the perhaps I could use the solution from this post. It would be best if my output images had 1 bit per pixel, since the range map should be essentially composed of zeros (species not present) and ones (species present).
Unless you know better options than ArcGIS? I also have at my disposal QGIS, GRASS and command-line GDAL tools.
