I am trying to add some forest elevations to a DEM using an ArcView (Basic) level license of ArcGIS Desktop. I have converted a polygon feature class of a forest into a raster with the same resolution as my DEM. Then I reclassed the forest raster to 15 (the height of the forest). This has resulted in a patchy raster with gaps of nothing between.
To get a raster that covers the entire study area I created a constant raster with the extent of the forest polygon and containing the value of 0. when I add the two rasters together I end up with a replica of my forest raster rather than a raster with forest cells of value 15 and 0 values everywhere else.
Any Ideas of how to fill in the gaps between my forest cells?
