Remote Access to Active Spatial Data Repositories

Due to the vast variety of geo-scientific tasks it is hardly imaginable that all of them could be solved within a single GIS. There will be always a need for special-purpose applications which could solve tasks not good enough covered by established GISs. It is natural for such application to benefit from general geoscientific data already accumulated in standard GISs. However, these data are not always available without significant losses inevitable during data conversions. Even in a larger degree it is true for data processing services provided by GISs.
