I have uploaded an image data overlying a DTM data set, carried out a viewshed analysis but eventually I got a black background. Cannot understand what's going on. Can someone explain please?

I recommend that you contact Blue Marble Support directly via email (email@example.com). Please provide a detailed description of your workflow, including screen captures of your viewshed options and the results, and sample data that can be used to reproduce the issue. Thank you.
