UTM Universal Transverse Mercator Coordinates UTM Exercise Locating the Grid UTM Guide USNG Sheet This 1km square is located at 706km E 4344km N Usually we need to be a bit more precise about a location! Using UTM

  1. UTM Universal Transverse Mercator Coordinates UTM Exercise Locating the Grid UTM Guide USNG Sheet

  2. 
 • This 1km square is located at 
 706km E 4344km N • Usually we need to be a bit more precise about a location!

  3. 
 Using UTM is Easy • Take a look at the “UTM Practice Map” handout. • Can you quickly determine what map feature is at: 
 755.2 km E 4255.4 km N

  4. 100m square example

  7. Using a 
 distance scale, 
 marked in meters, to measure 
 UTM coordinates

  8. There are many ways to write the same position... P r Kilometers Meters e c 755km E 4255km N 755000m E 4255000m N i s 755.2km E 4255.4km N 755200m E 4255400m N i 755.23km E 4255.48km N 755230m E 4255480m N o n 755.234km E 4255.483km N 755234m E 4255483m N | | V 755.200km 755 200m

  18. More about UTM

  19. Transverse Mercator Projection • Central meridian is selected by the map maker and touches the cylinder. • Maps using the projection can show the whole Earth, but directions, distances, and areas are reasonably accurate only within 15° of the central meridian.

  20. UTM Zones • World is divided into 60 zones. • Each zone is 6° of longitude wide. • Zones are numbered 1 to 60, starting at 
 180° and progressing to the east.

  24. Converting Lat/Lon to UTM

  25. Converting UTM to Lat/Lon

  26. Converting between 
 Lat/Lon and UTM • Save a waypoint in the position format you have the coordinate in. • Switch to the position format you want to convert to. • Recall the waypoint
