a vector of longitudes. |
From Wikipedia[1]:
The UTM system divides the Earth between 80S and 84N latitude into 60 zones, each 6 degrees of longitude in width. Zone 1 covers longitude 180W to 174W; zone numbering increases eastward to zone 60 that covers longitude 174 to 180E.
We take each interval to include the starting longitude and exclude the ending one, so e.g. Zone 1 is [-180, -174); Zone 2 is [-174, -168); ..., Zone 60 is [174, 180).
a vector of the same length as 'long' with the zone the longitude is in.
