The TatukGIS Project File stores a map design:
- references to layers files
- coordinate system setup
- visual design such as colors, styles, labels, fonts, symbols, etc.
A project can be stored in a:
- new .ttkproject file introduced in Developer Kernel 11 and Editor/Viewer 5
- old and obsolete .ttkgp file
Only the new .ttkproject format supports all new product features and is, therefore, the recommended storage. If maintaining compatibility with older product versions is a priority, the latest Developer Kernel and Editor/Viewer versions can still also save to the old .ttkgp format.
Starting with version 5.3, the Editor/Viewer seamlessly upgrades old projects to the new .ttkproject format.
