How are UTM coordinates measured on USGS topographic maps? (2024)

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). The UTM system consists of 60 zones, each 6-degrees of longitude in width. The zones are numbered 1-60, beginning at 180-degrees longitude and increasing to the east. The military uses their own implementation of the UTM system, called the...

The Universal Transverse Mercator (UTM) grid is not used on the Forest Service Visitor Map series because of the maps’ small scale and intended use. The more detailed Wilderness maps and Special Area maps published by the Forest Service might have UTM grid ticks. UTM grids are included on all US Topo maps (7.5-minute, 1:24,000-scale) published by the USGS after 2010. Order paper maps for...

Historical Topographic Map Collection (1884-2006) : The USGS policy about putting a full UTM grid on 7.5-minute (1:24,000-scale) topographic maps has changed over time. Beginning in the mid-1950s, the grid was indicated by blue ticks around the map at 1,000-meter spacing. In 1979, the ticks were replaced with a full-line black UTM grid. This decision was reversed in 1992, then reversed again in...

The State Plane Coordinate System (SPCS), which is only used in the United States, is a plane coordinate system (north-south and east-west lines are perpendicular) in which each individual state has between one to six zones, depending on the state's size and shape. This coordinate system’s high level of accuracy is achieved through the use of relatively small zones. The State Plane Coordinate...

Within the conterminous 48 states, the North American Datum of 1927 (NAD 27) to the North American Datum of 1983 (NAD 83) shift of the latitude/longitude graticule (lines showing parallels of latitude and meridians of longitude for the earth) is in the range of 10-100 ground meters. Changes to UTM values are generally larger, around 200 meters, and changes for other coordinate systems are...

The old coordinates were not wrong, just different. Positions obtained using the North American Datums of 1927 ( NAD 27 ) and 1983 ( NAD 83 ) are based on different earth shapes--or ellipsoids--and used the best technology available at the time. Mathematically, NAD 83 is a stronger datum because all previously existing horizontal stations and newer GPS surveyed stations were adjusted...

The U.S. Geological Survey (USGS) has been the primary civilian mapping agency of the United States since 1879. Some of the most well-known USGS maps are the 1:24,000-scale topographic maps, also called 7.5-minute  quadrangles . In 2009, the USGS transitioned from our hand scribed historical topographic maps to US Topos , which are computer-generated on a regular schedule using national databases...

The method used to portray a part of the spherical Earth on a flat surface, whether a paper map or a computer screen, is called a map projection. No flat map can rival a globe in truly representing the surface of the entire Earth, so every flat map misrepresents the surface of the Earth in some way. A flat map can show one or more--but never all--of the following: True directions True distances...
