I have a problem.
- I used the mosaic to raster tool to form one large raster of the study area.
- Using the clip tool, I clipped the boundary of the study area to this large raster map.
BUT! There is now a black rectangular box outside the study area boundary that I cannot remove.
This black area is showing as 'nodata', so I cannot remove it using the symbology function.
How can I remove the black background using ArcGIS Desktop?
