Some map datum define zero altitude, some don't. For those > that don't, we define mean low tide. Like the datum, what's wrong with providing an indication of the unit of the measurement? I think it is generally a bad idea to assume that all parties along a chain of transmission know what the data meant initially. This only adds a modest number of bits to the format, given that the number of choices appears to be on the order of two. _______________________________________________ dhcwg mailing list dhcwg@ietf.org https://www1.ietf.org/mailman/listinfo/dhcwg
