Blue Marble Geographics released GeoCalc 6.3. This fully object-oriented, cross platform coordinate conversion library is now completely interoperable with most major GIS software tools available today. GeoCalc 6.3 supports a direct match to all ESRI coordinate system definitions and a direct data source match to Autodesk, Safe Software, MapInfo and others. The ability to import a coordinate system from a GML file using GML v3.1 allows for the addition of new geometries, making GeoCalc-dependent software more compliant with ISO (International Organization for Standardization) standards. GeoCalc’s built-in ability to manage coordinate system metadata also increases the flexibility and scalability of the tool. (Blue Marble Geographics, Gardiner, Maine)
