FAQ
VFK to CG4 Conversion
What are VFK files?
VFK is the exchange format of the Czech real estate cadastre, the official register of land parcels, buildings, and ownership rights in the Czech Republic. A file of this type is a text file with the cadastral data of one cadastral area, published by the Czech Office for Surveying, Mapping and Cadastre. It lists the parcels and buildings together with their boundaries, the points that define them, the types of land use, and the legal relations such as rights of ownership and easements. Surveyors, municipalities, and software companies use it to receive cadastral data and to load them into their own systems. Since the introduction of the data protection rules in 2018, personal information about owners has been removed from the files that are issued.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
