Intergraph Corp is in final beta testing with a universal geographic information systems client that it says will be able to read data from just about any commonly used data format where geographic information is stored. Intergraph is hoping to have the GeoMedia client, now in the hands of about 400 independent software vendors and end users, in final shape by the end of the month. The interface, which will work with any Windows-based operating system, can be built into custom applications written in Visual Basic, Visual C++, PowerBuilder, Delphi, Excel, FoxPro and Access.
