The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth.Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.However, it differs from global latitude/longitude in that it divides earth ...

2024年6月22日 · In conclusion, UTM zone letters play a vital role in the UTM coordinate system, providing a unique identifier for specific locations on Earth’s surface. By combining the zone number, zone letter, and easting and northing values, accurate and precise mapping, surveying, and navigation can be achieved.

UTM zones extend from a latitude of 80° S to 84° N. In the polar regions the Universal Polar Stereographic (UPS) grid system is used. ... , south to north, beginning at 80° S with the letter C and ending with the letter X at 84° N. The letters I and O are skipped to avoid confusion with the numbers one and zero. The band lettered X spans 12 ...

2024年10月21日 · Click anywhere on the map to find out the UTM zone for that location. The UTM system divides the Earth into 60 zones, each 6° of longitude wide. The zones are numbered from 1 to 60, starting at 180° West and increasing eastward. Each UTM zone is also divided into latitude bands, labeled from C to X (omitting I and O).

2025年2月5日 · The Universal Transverse Mercator (UTM) system is a coordinate system that divides the world into a grid, allowing for precise location identification. Within this system, locations are described not just by numbers but also by letters. So, what exactly do these letters in a UTM zone mean? The letters in UTM zones specifically denote ...

2024年6月18日 · UTM coordinates are typically accurate to within a millimeter within a range of 3,000 kilometers from the central meridian. However, the accuracy can vary depending on the specific UTM zone and the methods used for measurement. What are the letters in UTM zone? UTM zones are identified by letters that range from C to X, excluding the letters I ...

Universal Transverse Mercator (UTM) is a coordinate system that maps the Earth's round surface onto a relatively accurate flat two dimensional surface. ... Band Letter (eg. 12U) In this convention, a Zone Number is followed by a Band Letter and is used to identify each 6 x 8 grid. They are working with maps of this size.

While the USNG is referred to as an alpha-numeric reference system for the UTM coordinate system, it is actually much more. The lettering scheme for the 100,000-meter Square Identification is designed such that any two-letter combination will not repeat itself but every 18° of longitude and a similar area in latitude.
