The TTKGP file type is primarily associated with 'TatukGIS' by TatukGIS. The TatukGIS Project File organizes a set of map layer files (such as SHP, MIF, DXF, TIFF, etc.), and the visual layer properties for each layer, into a single map project. This file type is associated with TatukGIS software products, e.g., free desktop GIS Viewer, desktop GIS Editor, the GIS Developer Kernel (SDK), and any custom application developed from the TatukGIS Developer Kernel.
