Features

• Implementation of the program is object-oriented. This includes type-checking and vector algebra for Cartesian objects.
• Units of measure are in linear and angular units.
• Supports common cartographic projections, including Mercator and Transverse Mercator.
• Provides access to a collection of 24 reference ellipsoids and 18 geodetic datums, which can be user-supplemented.
• Geodetic coordinate systems include geodetic curvilinear (latitude, longitude, ellipsoid height); Earth-centered, Earth-fixed, 3D Cartesian; and local geodetic Cartesian (ENU).
• Performs transformations among coordinate systems and datums.
• Includes common geodesy computations such as the forward and inverse problems and coordinate manipulations.
• Uses Oblique Mercator, Lambert conformal conic, orthographic, and stereographic projections, which are conformal projections for both ellipsoid and spherical implementations.
