WebThe type main classes of CRS are geographic or projection. A geographic CRS uses a 3D model of the Earth and ‘drapes’ the data over it. A projected CRS has the geographic CRS plus a map projection that has co-ordinates on a 2D plane. On the previous page, you explored the basic concept of a coordinate reference system. You looked at two different types of Coordinate Reference Systems: 1. Geographic coordinate systems:coordinate systems that span the entire globe (e.g. latitude / longitude). 2. Projected coordinate Systems:coordinate … See more Geographic coordinate systems (which are often but not always in decimal degree units) are often optimal when you need to locate places on the Earth. Or when you need to create global maps. However, latitude and … See more A geographic CRS uses a grid that wraps around the entire globe. This means that each point on the globe is defined using the SAME coordinate system and the same units as defined within that particular geographic CRS. … See more As you learned above, geographic coordinate systems are ideal for creating global maps. However, they are prone to error when quantifying distance. In contrast, various … See more

It can consist of a simple arbitrary reference system such as a 10 m x 10 m sampling grid in a wood lot or, the boundaries of a soccer field or, it can consist of a geographic reference system, i.e. one where the spatial features are mapped to an earth based reference system. market comps for real estate
