Thanks again, trying to understand how it works too.
This data is sampled at different lat and long points, still don't understand if I have a data comprising say 5 degrees latitude and 5 degrees longitude, then this data is square as an image but if you translate the angles into distance it means that different pixels will have different distance equivalents. So I don't know yet how microdem handles that, also I don't know how il2 handle it's maps data (the world is round also in Olegworld hehe)
