Study Notes
UTM System
- The UTM system is a grid system.
- In the UTM system, the Earth's surface is projected onto a cylinder that touches the Earth along a specific meridian.
- Meridians are circles that pass through both the North and South poles.
- Meridians converge towards the North Pole, which means they don't create a rectangular grid.
- The UTM system uses a rectangular grid.
- The northerly direction of the UTM grid is defined by a specific meridian, called "Grid North".
- Only on that specific meridian does "Grid North" align with "True North".
