![]() #UTM COORDINATES FULL#Most UTM users and GPS (Global Positioning System) units use the full value of the UTM coordinates. The military implementation of UTM (Military Grid Reference System or MGRS) drops the small digits and indicates the 100,000 meter square by a two letter identifier. The zones are numbered 1-60, beginning at 180-degrees longitude and increasing to the east. The UTM system consists of 60 zones, each 6-degrees of longitude in width. The millions and hundreds of thousands of meters are shown with small numbers and are sometimes dropped when giving UTM coordinate positions. UTM is the acronym for Universal Transverse Mercator, a plane coordinate grid system named for the map projection on which it is based (Transverse Mercator). Note that the large numbers adjacent to the tick marks around the perimeter of the map represent tens of thousands and thousands of meters. How do I read my UTM coordinates When reading a UTM coordinate, your reading should state latitude and then. Measurements can be made using a gridded mylar overlay, a paper scale, or a coordinate reader. Standing at the center of the marker shown on the map below, a GPS unit set to display position in UTM/UPS format. Type out the coordinates into the search bar using either the degrees, minutes, and seconds (DMS) format, the degrees and decimal minutes (DMM) format, or decimal degrees (DD) format then hit enter or click on the search icon. This narrows down the coordinate to a 100 meter or 10 meter square. Decimal degrees (DDD.DDDDDD) - GPS Format (DDD MM.MMM) - Sexagesimal (DDD MM SS) Extra functions: - You can locate yourself and convert these coordinates. You can convert your coordinates into 4 formats: - UTM. To make UTM measurements, subdivide the 1,000-meter grid squares into tenths or hundredths. UTM Coordinates Tool is a great tool to convert your coordinates into different formats. Some maps, including all those produced after 2009 ( US Topo maps) include full UTM grid lines. The UTM grid is a widely-used type of geospatial plane coordinate system in which positions are specified as eastings (distances, in meters, east of an origin) and northings (distances north of the origin). Likewise, the eastern (right) zone boundaries will have coordinates of 834 km at the equator and 515 km at 84 degrees north. A position defined by the coordinates (1,1) is located one unit to the right, and one unit up from the origin (0,0). At 84 degrees north latitude it is 465 km. As one moves away from the equator, the UTM east coordinate at the zone's western edge has larger and larger values. US Topo map showing latitude and longitude of the corner (38°N, -115.8750°W) and brown UTM gridlines (4,206,000 meters northing and 599,000 meters easting)Īlmost all USGS topographic maps produced after 1977 show UTM tick marks on the sides of the map (or a full-line grid) every 1,000 meters. The smallest value is 160 km and it is at the equator. ![]()
