Why is mosaic of rasters big, black rectangle in ArcGIS Desktop?


I downloaded NED rasters from USGS, and I now want to mosaic all of the rasters into one. I used the Mosaic to New Raster tool, but the output is a big, black rectangle. Am I missing something? I feel like I might be making a rookie mistake.




Answer



If you have not recalculated the statistics, you can do this by right clicking on the raster and selecting "Calculate Statistics"
