We have been using the TatukGIS Developer Kernel (ActiveX edition) for our severe weather and storm tracking solution for over 4 years now and we have evaluated many other GIS engines since. This latest DK version is the most efficient, most capable GIS engine we have ever seen. It blows away everything else on the market.
