1) In creating the RAINBOOL Image, I also needed an rain elevation model which I created using the vector file with mean annual precipitation contours (RAINCON).
2) With the RAINCON line vector file, I converted it into a point vector file (RAINPT) wich the LINTOPNT function.
3) The TIN interpolation was applied to RAINPT to create a rain tin surface vector image (RAINTIN).
4) Using the TINSURF operation on RAINTIN produced the rain elavation model (RAINDEM) raster image.
5) By reclassing the RAINDEM image, I created the rain boolean image (RAINBOOL) showing areas with mean annual precipitation greater than 20 inches.
