Universal Transverse Mercator System

Work with the Universal Transverse Mercator (UTM) worldwide coordinate grid

The transverse Mercator and polar stereographic projections are used to organize a worldwide coordinate grid. The Universal Transverse Mercator (UTM) coordinate system is a system of Mercator projections that are designed to limit distortion in each zone of the coordinate system. The UTM system supports many military, scientific, and surveying applications.

The Universal Transverse Mercator System

The Universal Transverse Mercator (UTM) system organizes the world into a regular nonoverlapping coordinate grid of quadrangles, called zones.

Create a UTM Map

This example shows how to create a UTM map that displays a single zone, in a 8-by-6 degree map window.

Set UTM Parameters Interactively

You can interact with a map of the world to select a UTM zone and adjust map settings, such as the limits, origin, parallels, and aspect.

Work in UTM Without a Displayed Map

This example shows how to select a UTM zone by specifying the coordinate of a location. You can then create a UTM coordinate system using the suggested ellipsoid vector of the zone.

Use the Transverse Aspect to Map Across UTM Zones

This example shows how to display areas that extend across more than one UTM zone by using the Mercator projection in a transverse aspect.
