What does the term UTM mean? Is UTM better or more accurate than latitude/longitude?

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...

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...

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...
