GeoProjection

GeoProjection
is an option for GeoGraphics that specifies the cartographic projection to use for the map.

DetailsDetails

  • GeoProjection can use any projection "proj" or {"proj",params}, where "proj" is any of the entities of GeoProjectionData and params are parameter rules like "StandardParallels"->{33,60}. GeoProjectionData["proj"] gives the default values of the parameters for the projection "proj".
  • GeoGraphics[,GeoProjection->Automatic] chooses a projection automatically. It will be "Mercator" for small scales, "LambertAzimuthal" for intermediate scales, and "Equirectangular" for large scales. It also chooses the "Centering" and "GridOrigin" parameters automatically.
  • The projection is applied to the geo background of the GeoGraphics map, as well as to its geo primitives, like GeoPath or GeoDisk.
  • AbsoluteOptions can be used to give explicit projection information for a GeoProjection with Automatic setting.
