FAQ
ITF to CAL Conversion
What are ITF files?
ITF is a text file with geographic data in the INTERLIS 1 transfer format, a Swiss standard for passing data between land information systems. It is the delivery that goes together with a model file with the .ili extension: the model says what kinds of objects exist and what their attributes mean, and the ITF file holds the objects themselves, such as parcels, buildings, boundary lines, and survey points, with their coordinates and attributes. The format was created by the Swiss Federal Directorate for Cadastral Surveying in the 1990s and is still used for official surveying data in Switzerland. Because the data and the model are kept apart, one model can be used for many deliveries, and new deliveries are checked against it.
What are CAL files?
A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
