Toolbox should output contributing area in sq km, not fractional area

[cherkaue]

I have posted an issue to the repository to update the ArcGIS toolbox next time I am in the office, so that the tool will produce a fraction file with contributing area, rather than fractional area, directly from the spatial analysis process.

Toolset now outputs raster files with both fractional area and total area in what is assumed to be square kilometers (works if high-res processing is completed in projection with meters are the spatial unit). Should be able to add a pull down menu for the input units (or perhaps select the source layer from a pull down list). Either option would better ensure that output files used for the routing model are in the correct units.
