Each country has a UTM zone to establish the coordinates of its cities. Each UTM zone comprises 20 bands that are represented by the letters C through X. There are 60 UTM zones on the planet.
The main characteristics of UTM coordinates are:
- Use cylindrical projection: the globe on a cylindrical surface.
- Use transverse projection: the axis of the cylinder coincides with the equatorial axis.
- Preserves the value of the angles.
- It is very easy to measure distances with this coordinate system.
- Grids are used to represent parallels and meridians.
- It cannot represent the poles.
- The distances depend on the knowledge of the sphere-cylinder points of tangency, in a direction perpendicular to the cylinder.
