| May 14, 2021 at 4:50 | comment | added | hbk | I tried to create a fishnet grid of 10x10 of the study area but got the error “ERROR 001018: Number of output features exceeds OID limit (2,147,483,647)“. I then tried a 100x100 grid and that ran for 20 mins before I stopped it. I then ran a 500x500 fishnet (took about 10 mins) and intersected it with the boundary polygon, ran the Euclidean distance with the intersection result as the mask and it worked! Another solution is to create the distance raster with the polygon as extent (not mask), the use the extract by mask tool using the boundary polygon as the mask. This took a few minutes. | |
