Developer Kernel Editions The TatukGIS Developer Kernel (DK) is a set of GIS libraries, each compiled natively for a particular development platform, enabling custom GIS application development for just about any operating system and the web. Each library (i.e., DK product edition) features essentially the same object-oriented API, logic, and comprehensive geospatial functionality, with differences only as required by the different technologies. Highly similar application source code across development platforms enables relatively easy migration between platforms, operating systems, and the web.
