|ground elevation in typical system|
|Status:||Proposed (under way)|
|Definition:||Ground elevation expressed in the regionally common reference system (as found on signs)|
A tag for the ground elevation in the regionally common reference system. It works similar to ele=* with the only difference that ele refers to WGS84, while ele:regional is in whatever reference locally would be expected to be used. Therefore you can copy elevation numbers from signs without having to bother with the conversion or the reference used.
Units are the ones that are used on the sign. If you want you can add units to the value but it isn’t required and if no units are tagged the value is supposed to be given in regionally common units.
