WebThis is a combination of a GCS + a Projection. The GCS tells your data where to draw on the earth, and the projection tells the map how to distort the earth onto a flat surface. Every PCS contains a GCS. Here’s the … WebGCS employs the Gauss–Kruger coordinate on the XOY plane and altitude on the Z-axis. The origin of GCS is the intersection of the Greenwich Meridian and the Equator. Parallel to NCS, the X-axis pointing to the north, the Y-axis pointing to the east, and the Z-axis pointing upward, a left-handed coordinate system is formed, as shown in Figure 2.

WebFeb 27, 2016 · The difference is that WGS 84 is a geographic coordinate system, and UTM is a projected coordinate system. Geographic coordinate systems are based on a spheroid and utilize angular units (degrees). Projected coordinate systems are based on a plane (the spheroid projected onto a 2D surface) and utilize linear units (feet, meters, etc.). WebOct 6, 2024 · Geographic Coordinate System.
