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.
Thanks

For the northings about 10,000,000m max For the eastings, 0ish to 1,000,000ish meters since the central meridian of every zone is 500,000 m and you will never get to 0 or 1,000,000 Remember the equator has a false northing of 0m in the northern hemisphere, increasing poleward and 10,000,000m in the southern hemisphere decreasing to the South Pole
