Classes
- Angle
- Represents an angle.
- Boundary
- Earth
- Represents Earth planet.
- EarthCenteredEarthFixed
- Earth-centered, Earth-fixed is a cartesian spatial reference system that represents locations in the vicinity of the Planet (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass.
- EarthCenteredInertial
- Earth-centered inertial (ECI) coordinate frames have their origins at the center of mass of Planet and are fixed with respect to the stars.
- EPSG4326
- The Mercator projection is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because of its unique property of representing any course of constant bearing as a straight segment.
