Hi Martin, thanks for your reply.
The point is that it is difficult to get the elevation value..., it´s easier for the azimuth angle using a compass image overlay. I´ve been trying with the viewshed tool in GE Pro, but it´s a tedious process.
I think there must be an easier and simple way to obtain that data, so if someone else have an idea about it, it would be an excellent share.
I leave some images from GE.
Best regards,
Boris.
