I’ve searched high and low to no avail looking for any existing tools, scripts, ArcGIS geoprocessing steps that will output an adjacency table something like this:

VALUE,ADJ_VALUE,LENGTH_EDGE (m)

1,2,45

1,3,90

1,9,30

1,14,150

2,1,45

2,11,30

2,16,45

2,3,90

3,1,90

3,2,90

based on a region grouped raster layer. I’m aware of existing tools and methodologies out there to accomplish this in vector, but my dataset is massive and would require that I break into smaller chunks if I convert to polygon. I would like to avoid having to do this, if possible, by generating an adjacency table straight from the region grouped raster.

Thanks
