Location Component Schema. This is a location that is expressed in terms of 2D coordinates. In order that the location be understood, the coordinate reference system (CRS) must be known. The survey location is given by a pair of tagged values. The pairs may be: (1) latitude/longitude, (2) easting/northing, (3) westing/southing, (4) projectedX/projectedY, or (5) localX/localY. The appropriate pair must be chosen for the data.
