UTM, or Universal Transverse Mercator, is a global map projection system that divides the world into a series of zones. Each zone is projected using a transverse Mercator projection, which minimizes distortion in that specific area. This system is widely used in mapping and navigation, allowing for accurate representation of geographic locations. The UTM system uses a grid of coordinates, measured in meters, to pinpoint locations within each zone. Each zone is identified by a number and a letter, making it easier for users to find and communicate specific locations. This method is particularly useful for activities like GPS navigation and land surveying.
