Hi,

I think there is a problem calculating the angles (start and swept) of transmitter between viewshed runned throught GUI and viewshed executed throught scripting language. Seem that the swept angle calculated with script is counterclockwise and the start angle start at 90° rather than 0° (North). This the difference using Global Mapper 23.1.0 (b030322) and same parameters for GUI e Script:
