The strategy will be to reclassify the values of each of these rasters. We'll make the value “one” if the
zone meets the requirement, and zero or NODATA otherwise.
For Landuse_rr2m, this means changing all the values to “0,” except for landuse type code
“300,” which we change to “1.”
For Soils_rr2m, we will change values of “0” and “1” (both of which indicate unsuitability) to
“0.” We will change the values “2” and “3” to “1.”
For Sewer_buf_rr2m, we will replace the numbers of meters within which building is allowed
(300) with “1,” leaving NODATA alone.
