I'm totally a newbie with geo tools. I'm using Sharpmap as I'm working with C#.
I have a map where I can put an item on a UTM Location with E,N Zone and number. So the item appears on the desired position.
The problem comes when I want to move the item to a new position. So, for example, I want to increase easting by 2000 meters.
How can I calculate if my item has crossed to a new zone? The easting ranges differ from equator to the poles, am I right? Is there a way to calculate easting ranges of a certain zone?
What is the best way to work with location points in different zones -- for example, to calculate distance between them?
