# 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.
• gives the list of available cartographic projections.
• 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 or parallels {1, 2} "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:
 long central meridian {lat,long} central parallel lat and meridian long {{lat,long},} point on center line and azimuth (Oblique Mercator) {{lat1,long1},{lat2,long2}} two points on center line (Oblique Mercator)
• Valid settings for "ReferenceModel":
 r radius 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
• Available projections include:
 "Albers" Albers equal-area conic "Bonne" Bonne "Cassini" Cassini "CylindricalEqualArea" cylindrical equal-area "CylindricalEquidistant" cylindrical equidistant "EckertIV" Eckert IV "EckertIV" Eckert VI "Equirectangular" simple cylindrical equirectangular "Gnomonic" gnonomic "LambertAzimuthal" Lambert azimuthal equal-area "LambertConformalConic" Lambert conformal conic "LambertConformalConicNGS" Lambert conformal conic (NGS) "LambertCylindrical" Lambert cylindrical "Mercator" Mercator "MillerCylindrical" Miller cylindrical "Mollweide" Mollweide "ObliqueMercator" oblique Mercator "ObliqueMercatorNGS" oblique Mercator (NGS) "Orthographic" orthographic "Stereographic" stereographic "TransverseMercator" transverse Mercator "Polyconic" polyconic "Robinson" Robinson "Sinusoidal" sinusoidal "VanDerGrinten" van der Grinten "WinkelTripel" Winkel tripel
