Geo data

Official data - position

Positional accuracy - what does that mean?

Anyone who has always wondered how fiber optic expansion works may find the answer here. Official data plays a central role here.



The prioritization of areas to be connected is crucial for the development of a roll-out plan. Knowing the potential of the households and companies to be supplied is essential. Without this knowledge, a solid cost estimate of such a project is not possible. Georeferenced information about the location of the buildings to be connected is therefore a sensible and valuable investment, as every meter of fibre optic expansion costs money. Obviously, the more accurate this information is, the better.



What information is this? The answer is simple: precise coordinates and house perimeters.


Nexiga generates new and independent products from official data such as coordinates and house perimeters from the ZSHH* (Central Office of the Official Land Surveying Offices). The approx. 21.5 million Nexiga house coordinates and approx. 53.5 million Nexiga house per imeters are generated nationwide via geo-processes. These can be used for a wide variety of analyses - always precisely where maximum accuracy, determination of potential and expansion are required.



The attractive price model is based on the following components.

Areas of use and applications


We are currently working on the Nexiga building blocks to expand our geodata pool. Building blocks are created using geo-processes based on data from the Federal Agency for Cartography and Geodesy (BKG). The approx. 3 million Nexiga building blocks are generated nationwide for settlement areas and can be a useful unit of analysis for many applications.

Still important to know!

*ZSHH = The "Central Office for House Coordinates and House Envelopes " (ZSHH) set up at the Bavarian State Office for Digitization, Broadband and Surveying bundles selected follow-up products based on the real estate cadastre of the surveying administrations of the federal states and provides these centrally to customers on behalf of the states at uniform fee and licensing models and in uniform nationwide data formats. The ZSHH becomes active whenever users wish to license data from more than one Federal state .
