藍伯特投影(Lambert Conformal Conic) 圓錐投影(Conic Projection) 等積投影 (Equal Area ): 形狀正確, 面積正確

麥卡托投影(Mercator projection) 正形投影(conformal): 角度正確, 方向正確 圓柱形投影(Cylindrical Projection)

The Universal Transverse Mercator (UTM) Projection Transverse Mercator because the cylinder is wrapped around the Poles, not the Equator A type of cylindrical projection Implemented as an internationally standard coordinate system Initially devised as a military standard. Uses a system of 60 zones Maximum distortion is 0. 04%

Universal Transverse Mercator (UTM) Projection 國際橫麥卡托投影

UTM Coordinates In the N Hemisphere define the Equator as 0 m. N The central meridian (中央經線) of the zone is given a false Easting of 500, 000 m. E Eastings and northings are both in meters allowing easy estimation of distance on the projection A UTM georeference consists of a zone number, a six-digit easting and a sevendigit northing E. g. , 14, 468324 E, 5362789 N
