I have been attempting to create a total cover map of a 4x4 km target area.
I clipped the target area to my desired size and used the create polygon feature of ArcGIS to define all of the areas as 'meadow', 'roadside', 'uninhabitable' and 'wooded' ( I was very careful to make sure that all of my vertices on my multiple polygon layers connected so that there was no undefined space) .
I am trying to convert this entire 4x4 section into a seamless ASCII grid file so that it can be run by the program Circuitscape.
I have tried converting all of the polygons into individual rasters and running the mosaic rasters tool provided by ArcGIS, but this results in a huge mess.
any advice that can be offered?
