Our company is well known for processing high quality data and so we have decided that we could get involved in the analytical town planning data process right in the preparatory phase of the ATPD process, which consists of digitally processing data from data providers. The providers are obliged by Law No. 183/2006 Coll. on town planning and construction rules of procedure, to provide data: “primarily in digital form …, technical infrastructure approved after the construction law becomes effective in the coordinate system Unified Cadastral Trigonometric Network at the cadastral map scale or at a more detailed scale. For technical infrastructure completed and approved before this law becomes effective planimetric data must be provided in an accessible system…“. The law-makers have done it again! This particularly concerns data on technical infrastructure, environmental protection, etc.
For a relatively long time now we have worked on the question of how to process the unbelievable amount of information and documentation drawn with a blunt crayon, written on a typewriter, digitally processed data without any form of signature, digitally processed data that is printed off and then scanned … and so on. There is obviously a need for a conceptual means of dealing with geodata at a national level. Municipalities have not been given any rules as to how to unify this data or, primarily, how to manage and update it. The only support has come from the Regional Authorities and they have joined forces with the municipalities as far as they are able. The individual regions have recommended their municipalities to use data models, so that the data can be shared at least on a regional basis.
GEODIS BRNO creates the data part of the ATPD for the following municipalities with extended authority: Boskovice, Hodonín, Veselí nad Moravou, and Znojmo. Before the data is processed it always undergoes a thorough analysis, which gives a detailed description of the data sets from each provider; only after this has been done is the data actually processed. This gives a detailed description of each file (metadata), which is then worked on by our team; however, what is far more crucial is that the official in charge of administering the data must be able to find his way around the data and must be prepared to act if he is required on the spot to provide data about a particular territory or if he wants, according to the law,: “to publish and update analytical town planning data by means that allow remote access”. All communication related to the individual data sets is also logged on a continual basis.
Throughout this project we have placed great emphasis on clearly identifying each feature that crops up. Each provider guarantees the quality of the data they submit, and are thus responsible for the consequences of any decisions involving such data. The data model of the Region of South Bohemia prescribes the data structure, which in many cases we have supplemented or made more precise in collaboration with the Regional Authority. The Regional Authority has put us in the ATPD working group to that we can do our utmost to help optimise the data acquisition process for ATPD.
