Each has advantages anddisadvantages. These have been entirely superseded by Charles F. ArmyTechnical Manual TM 5-241-8 (complete citations below). GeologicalSurvey Professional Paper 1395 and U. Previously, the two basic references for converting UTM and geographic coordinates wereU.S. Also, old World War II era maps of Europe apparently used a single gridfor all of Europe and grids in some areas are wildly tilted with respect tolatitude and longitude. I saw US military maps of Germanyshift their UTM grids by about 300 meters when a more modern datum was used forthe maps. This means that different maps will have different grids depending on thedatum used (model of the shape of the earth). UTM grids, on the other hand, are created by laying a square grid on theearth. But there is no way to determine your UTM coordinatesexcept by calculation. If you can see the stars andhave a sextant and a good clock set to Greenwich time, you can find yourlatitude and longitude. Latitude is determined by the earth's polar axis.Longitude is determined by the earth's rotation. I get enough inquiries on this subject that I decided to create a page forit.Ĭaution! Unlike latitude and longitude, there is no physical frame ofreference for UTM grids.
