Wolfram Research released GeometricalGeodesy, a new Mathematica application package for solving fundamental geodesy and analytical cartography problems. Primarily intended for computing coordinates in a variety of datums and coordinate systems, the package combines the core elements of geometrical geodesy into a single, comprehensive framework. Complete integration with Mathematica offers significant advantages for accurate numerical computation, exact symbolic analysis and visual interpretation of results. GeometricalGeodesy is for those needing high-precision computations of distances and directions about the Earth or those wanting to explore the consequences of the shape of the Earth on coordinates and the information derived from them. Features of GeometricalGeodesy include: object-oriented implementation for positions, including type-checking and vector algebra for Cartesian objects; linear and angular units of measure with system conversions; access to a collection of 24 reference ellipsoids and 18 geodetic datums, which can be user-supplemented; use of geodetic curvilinear (latitude, longitude, ellipsoid height), Earth-centered, Earth-fixed, Cartesian (XYZ), and local geodetic Cartesian (ENU) coordinate systems; transformations among coordinate systems and datums; common geodesy computations, such as forward and inverse problems and coordinate manipulations; and cartographic projections, such as Mercator, Transverse Mercator, Oblique Mercator, Lambert conformal conic, orthographic and stereographic, for both ellipsoid and spherical implementations. GeometricalGeodesy can be downloaded from the Wolfram Research web store for Windows, Mac OS X or Linux platforms. The package is designed for use with Mathematica 5.1 or higher. Academic and government discounts are available. (Wolfram Research, Champaign, Ill.)
