Supported Coordinate Reference Systems

There are two common types of coordinate reference systems (CRS) used in engineering:

  • A geographical coordinate reference system uses latitude–longitude coordinates to map the earth’s spherical surface. More information on geographic coordinate reference systems is provided here.
  • A projected coordinate reference system uses X-Y coordinates (commonly called Northing and Easting) to project maps of the earth’s spherical surface onto a two-dimensional Cartesian coordinate plane. More information on projected coordinate reference systems is provided here.

Because an engineering project model utilizes X-Y coordinates to define elements of the model, only projected coordinate reference systems can be used. However, CivilGEO’s software will automatically reproject data sets that use geographical coordinate reference systems to the assigned Map View projected coordinate reference system if the data lies within the projected CRS bounds.
