I'm working in the development of an user interface in which the user should be able to enter a UTM coordinate in the following format:
I don't know much about these type of systems, but I do want to provide a good user interface with client side validation. I know that the zone will be 1-60 with a plus or minus sign to determine the hemisphere. I would like to know what would be the valid range to input for easting and northing field. Currently I'm just checking if 'Double' number is provided, but I know the valid range should be more narrow.
