Study Notes
UTM System
- The Universal Transverse Mercator (UTM) system is an example of a grid system.
- The UTM system uses a transverse Mercator projection, where the Earth's surface is wrapped around a cylinder that touches the spheroid along a chosen meridian.
- A meridian is a circle running around the Earth passing through both the North and South geographic poles.
- The UTM system's grid lines form a rectangular grid system, with north determined by a specified meridian of longitude.
- "Grid North" is aligned with true north only on the specified meridian.
