Integrated Geodesy概要1.doc

Integrated Geodesy GIS Mathematica 7 adds support for advanced high-precision geodesy, providing a modern foundation for accurate geospatial information and computation. With comprehensive support for all standard reference ellipsoids, datums and projections, Mathematica 7 streamlines the process of importing, combining and computing with geospatial data from varied sources—as well as supporting symbolic geodesy, fully integrated with Mathematicas broad mathematical computation capabilities. Import of all common terrain and map file formats. ? Comprehensive built-in database of geodetic datums and reference ellipsoids. ? Geodetic forward and inverse problems. ? Geographic, ECEF, and local tangential ENU coordinate systems. ? Full 14-parameter datum transforms, including time dependence. ? Extensive built-in library of cartographic projections. ? Spherical and high-precision ellipsoidal projections supported. Arbitrary conversions between geodetic and grid coordinates. Fully customizable reference ellipsoids, datum and projections. Arbitrary precision geodetic computations. Exact symbolic and algebraic geodetic computations when possible. Integration with built-in city, country and astronomical data. Convenient support for DMS and decimal angles. ? GeoIP-based default location-finding service. ?
