Maine, USA, 16 June 2006: Blue Marble Geographics announced an update to their GeoCalc 6.2 developer tool kit. This object-oriented, cross platform version of Blue Marble’s coordinate conversion libraries is created to meet the accuracy and data conversion needs of GIS and mapping programmers.

GeoCalc 6.2 is an expansion of the existing GeoCalc libraries. The developer kit now supports over 50 projections including Bipolar Oblique Conformal Conic and Oblique Mercator Azimuth. It has over 12 Datum Shifts including Molodensky-Badekas 10 Parameter Shift and the Ordnance Survey National Grid Transform of 2002. Two new height models added are: Colombia Geoid Model of 2004 and Earth Geopotential Model 1996 (EGM 96). Many new objects and methods have been added along with speed optimization for data source load, browsing and querying. Finally, the library supports the latest version of the OGP’s EPSG Geodetic Parameter Dataset, v6.10.

GeoCalc 6.2 relies upon human readable capabilities XML data source and provides support for WKT (well-known text) definitions as per the Open GIS Consortium specifications. This product will support all previous GeoCalc coordinate system classifications, and will support any other coordinate system library definitions.
