Surface Area to Planar Area Arc-Chord Correction Crashes

[ailich]

Surface Area To Planar Area Tool crashes once it has to calculate triangle area. This is on a 2m resolution bathymetry grid with 4908 columns and 13,948 rows. The calculation works on a resampled version of this data at 10 meter resolution.

@ailich thanks for the report, I haven't seen this issue before, but typically something is going wrong with writing the data in cases like this. Could you report what the earlier message "Set scratch workspace to" line reads? Could you confirm how much free space you have on the disk where the scratch workspace is located? Another possibility is that this operation is consuming too much memory, I'll see if I can reproduce locally with a similarly large raster.

I reran it using a tif and set it to my external hard drive which has 500GB free so there should be enough space there. I still get the same error however.

It ran using a .asc file instead of a .tif or a geodatabase file and although it took much longer (51 minutes), it did run. Calculating BPI also seems not to work for tifs but works for .asc files.
