Questions fréquentes
When do you use each coordinate system?
Geographic (lat/lon): mapping, GPS. UTM: engineering, accurate distance/area. Projection choice matters.
Why do projections distort?
Can't flatten sphere without distortion. Different projections minimize different distortions (area, shape, distance).
