Decimal Degrees UTM Conversion
Decimal degrees (DD) UTM Conversion express latitude and longitude geographic coordinates as decimal fractions and are used in many Geographic Information Systems (GIS), web function applications such as Google Maps, and GPS devices. Decimal degrees are an alternative to using degrees, minutes, and seconds (DMS). As with latitude and longitude, Decimal degrees UTM Conversion is the values are bounced by ±90° and ±180° each.
Positive latitudes are north of the equator, negative latitudes are south of the equator. Positive longitudes are east of Prime Meridian; negative longitudes are west of the Prime Meridian. Latitude and longitude are usually carried in that determine, latitude before longitude. UTM grids, on the other hand, are created by laying a square grid on the earth. This means that different maps will have different grids depending upon the datum used (model of the shape of the earth). I saw US military maps of Germany shift their UTM grids by about 300 meters when a more modern datum was used for the maps. Also, old World War II era maps of Europe apparently used a single grid for all of Europe and grids in some areas are wildly tilted with respect to range and longitude.
