    About the Universal Transverse Mercator (UTM) family

    Nord Sahara 1959 / UTM zone 32N is a Universal Transverse Mercator zone — a 6°-wide belt of the worldwide UTM system, in metres, centred on a meridian carefully chosen so distortion stays low across the zone. It is the everyday working grid for GPS-derived surveying in Algeria.

    The classic field mistake with UTM is using the wrong zone: a point one zone away is easily hundreds of kilometres off. Always confirm the zone number (and the hemisphere) before importing coordinates, and remember that UTM eastings are offset by a 500 km false easting so they never go negative.
