How to get the Radius of the displayed map area. The map is being rendered using ViewByScale & the image height = 400 & width = 450.
1. map scale = 5000000;
2. Image height = 400;
3. Image widht = 450;
4. Default dpi. (should this be taken into account).
What woud be the radius of the visible area of the map?
Any ideas appreciated.
thanks in advance.
