Hoping someone can help me with this one, as I'm at a loss!
I'm using the Tabulate Area 2 tool (similar to Tabulate Area, except that it can handle overlapping polygons, of which there are many in my data). I have two shapefile feature classes (EW_buff3 and ES_buff2) that were made by buffering points in my map area. The "class" raster is a statewide land use raster. (In brief, I'm trying to tabulate the amount of each type of land use in each circle of EW_buff3 and ES_buff2).
Here's the issue: when I run the tool comparing either EW_buff3 or ES_buff2 to the lower peninsula land use raster, I only get 693 cases in the output table. (EW_buff3 contains 2007 cases, and ES_buff2 contains 3454, so it doesn't seem to be anything about those files that is resulting in the 693-case result.)
The geostatistical analysis environment is set to include all coincident points, so it doesn't seem to be flattening the overlapping points into a single layer.
I'd just carried out this same function successfully with two other shapefile feature classes (R1_buff and R2_buff) that were created in the same manner as EW_buff3 and ES_buff2, using the same land cover raster, so I know it's not a basic problem with my process (though I will note, that those two feature classes both contain fewer than 693 cases, so if there's something causing an upper limit to the number of cases processed, that issue wouldn't have shown up with them).
I've examined the Tabulate Area 2 output table to identify some of the missing cases (seeing with FID numbers aren't listed) and going back to the EW_buff3 and ES_buff2 tables, but there doesn't seem to be anything unique about those records not being tabulated.
I'm using ArcGIS 10.3.1 for Desktop.
What might I be missing?? I'll check any suggestions you think might be causing this! Thanks!
