This libary exports a subset of package:geobase/geobase.dart.
Usage: import package:geobase/geodesy.dart
Classes
- Ellipsoidal
- The base class for calculations related to the Earth surface modeled by ellipsoidal reference frames.
- EllipsoidalVincenty
- Distances & bearings between points, and destination points given start points & initial bearings, calculated on an ellipsoidal earth model using ‘direct and inverse solutions of geodesics on the ellipsoid’ devised by Thaddeus Vincenty.
- GeodeticArcSegment
- A geodetic (geographic) arc segment between the origin position and the destination position along a geodesic.
- SphericalGreatCircle
- Latitude/longitude points on a spherical model earth, and methods for calculating distances, bearings, destinations, etc on (orthodromic) great-circle paths.
- SphericalGreatCircleLineString
- Calculations for line strings (as an iterable of geographic positions) on a spherical model earth (great-circle paths).
- SphericalRhumbLine
- Latitude/longitude points on a spherical model earth, and methods for calculating distances, bearings, destinations, etc on (loxodromic) rhumb lines.
