I have a multipolygon shapefile of species distributions containing data in the attribute table on the threats each species face according to the IUCN threat categories. The distributions of some species naturally overlap. I also have a grid, in the form of a shapefile, with a set cell size (30 Arc Seconds). I am interested in creating a raster containing threat frequency using the grid for defining cell size. In other words, a raster where each cell (as defined by the grid) will have data such as Threat A = 3; Threat B = 0; Threat C = 4 etc.
Is this possible? I am currently working in ARC Pro but am also comfortable working within r studio.
