So here's the problem. I have two rasters containing bathymetry data: one containing the bathymetry of the sea floor, we'll call this raster1, and another containing the difference between two previous scans of the same area, we'll call this raster2. I have to query raster2 such that any areas where the value is >10% of raster1's value will be highlighted. I tried to do this through the Extract by Attribute in ArcGIS but could not figure out the SQL statement. Any ideas on what the SQL query would look like?
