Using Arc 10.2.2 with the Spatial Analyst extension, I have a single band, signed integer, 8-bit raster. I need to reclassify cells within that raster based on their Euclidean distance to other cells within that same raster.
For example, if a cell with value 2 is within 100 meters of any cell containing value 5, then reclassify the value 2 cell to value 3. And so on.
I considered FocalStatistics, but none of that tool's statistic types (mean, majority, etc) met my needs.
A search on the topic turns up examples where the proximity is to features within a separate vector layer, but nothing on proximity within the same raster.
