Gardiner, Maine - Blue Marble Geographics has announced that Microsoft Corporation has licensed its GeoCalc.NET software developer toolkit to enhance and expand the data processing capabilities required to create Virtual Earth.
GeoCalc 6.2 is an object-oriented, cross-platform software developer tool kit designed for complex coordinate system definition and conversion. The tool uses an XML data source and provides support for well-known text (WKT) coordinate system definitions per the Open GIS Consortium specifications. The human readable capabilities of the XML data source in GeoCalc are important for ease of use in geodetic development projects.
GeoCalc’s coordinate system datasource offers more than 3200 predefined coordinate systems, more than 1100 datum shifts, 50-plus mathematic projections, local and global vertical datums, and the full and current EPSG coordinate system datasource.
GeoCalc’s dialogs enable the user to define custom systems, ellipsoids, datums, datum shifts, and units without having to edit a text file. The tool also supports coordinate system definition directly from TAB or PRJ files.
