Função de convesão LatLong para UTM grid: longitude-vertical zones vs latitude-horizontal bands,
UTM zones are numbered (UTM Zone Number) from 1
to 60
starting from 180° longitude at the International Date Line and proceeding eastward. Each zone is 6° longitude wide. Therefore Zone 1
lies between 180°W to 174°W longitude lines, Zone 2
is between 174°W and 168°W longitude lines, and Zone 60
lies between 174°E and 180° (International Date Line) longitude lines. Ver também Wikipedia/UTM Zone.
Each zone is divided into horizontal bands, 8° of latitude wide. The 20 bands are labeled with letters (UTM Zone Designators), beginning with C
and ending with X
from south to north. Letters I and O are omitted to prevent confusion. Note that letter N
designates the first latitude band above the equator (so any letter after N
refers to northern hemisphere and any N
refers to a southern). Ver também Wikipedia/UTM Latitude bands.
Overlap problem: somente entre UTM zones (as UTM bands dentro de uma zona não apresentam problema de sobreposição).
