Do all USGS 7.5 minute topographic maps show the UTM grid?
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 1994, but the 7.5-minute topographic program was winding down by this time and relatively few maps were affected. Maps published over National Forests in cooperation with the U.S. Forest Service do not show the full grid regardless of their vintage.
US Topo maps (2010-present): All US Topo maps published after 2009 have a full UTM grid that is implemented in conformance with the U.S. National Grid standard. US Topo maps in the GeoPDF format are layered documents, giving users the option to turn the grid off.

How are UTM coordinates measured on USGS topographic maps?
The UTM ( Universal Transverse Mercator) coordinate system divides the world into sixty north-south zones, each 6 degrees of longitude wide. UTM zones are numbered consecutively beginning with Zone 1, which includes the westernmost point of Alaska, and progress eastward to Zone 19, which includes Maine. If UTM ticks are shown on a USGS topographic map, the zone is indicated in the credit legend in...
What does the term UTM mean? Is UTM better or more accurate than latitude/longitude?
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...
Why do Landsat scenes in the Southern Hemisphere display negative UTM values?
Traditional Universal Transverse Mercator (UTM) convention distinguishes between the Northern and Southern Hemispheres. In the Northern Hemisphere, the UTM zone is a positive value or identified as UTM North. In the Southern Hemisphere, the UTM zone is a negative value or identified as UTM South. UTM North scenes in this convention have a false northing value of 0, while UTM South scenes have a...
Why don't U.S. Forest Service Visitor maps have Universal Transverse Mercator (UTM) grids?
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...
