GeoProjectionData

GeoProjectionData["projection", "property"]
gives the value of the specified property for the specified cartographic projection.
GeoProjectionData["projection"]
gives the complete options for the default form of the specified projection.
  • GeoProjectionData["projection", "Name"] gives the full name of projection "projection".
  • GeoProjectionData["Spherical"] gives the list of all projections that refer to a spherical model.
  • GeoProjectionData["Ellipsoidal"] gives the list of all projections that refer to an ellipsoidal model.
  • GeoProjectionData["projection", "Properties"] gives the names of all parameters and properties available for the projection specified by "name".
  • GeoProjectionData["projection"] gives a result of the form {"projection", opt1->val1, ...} where common options opti include:
"Centering"latitude and longitude defining the origin of the projection
"StandardParallels"standard parallel Phi or parallels {Phi1, Phi2}
"CentralScaleFactor"scale factor at the central meridian or center of projection
"GridOrigin"grid coordinates {e, n} of the central parallel and meridian
"ReferenceModel"what reference sphere or ellipsoid to use
  • Typical settings for "Centering" include:
longcentral meridian
{lat,long}central parallel lat and meridian long
{{lat,long},Alpha}point on center line and azimuth (Oblique Mercator)
{{lat1,long1},{lat2,long2}}two points on center line (Oblique Mercator)
  • Valid settings for "ReferenceModel":
rradius of reference sphere
{a,b}semimajor and semiminor axis of reference ellipsoid
{a,{invf}}semimajor axes and inverse flattening
"name"name of the geodetic datum or reference ellipsoid
