Extending the INSPIRE schemas for administrative purposes on the national level

The Czech Republic has a complex system of databases containing administrative data, such as cadastral zonings, parcels, addresses, polygons of administrative and non-administrative units, polygons and definition points of buildings etc. Data are integrated within the System of Registries, containing four independent registries. Administrative data and data about buildings and addresses for the use in this registry comes from the Registry of Territorial Identification, Addresses and Real Estates. Moreover, cadastral data are originally integrated in the Information System of the Cadastre of the Real Estates, that is not part of the System of the Registries. National and INSPIRE data sets are based on those databases and both of them have advantages and disadvantages. National data set for cadastre of the real estates contains detailed information about cadastral zonings and cadastral parcels, but the data are rather complicated to interpret and also format requires deeper knowledge of problematics. On the other side, INSPIRE data set is using standardized GML 3.2.1 format, but the content of the model is meager compared to the original database. Situation is very similar within the scope of Administrative Units. According to the INSPIRE Specifications, only four levels of hierarchy are required, but there are much more units on different level of hierarchy. Format used for representation of data from the Registry of Territorial Identification, Addresses and Real Estates is based on GML 3.2.1, but after years of enhancing and repairing, differences between pure GML and Exchange Format for the Registry of Territorial Identification, Addresses and Real Estates are way big. Moreover, for the purposes of only administrative and other units, format is a way too complicated. With the experience gained from the creation of extended XSD schemas according to the application schemas for BuildingsExtended, new models and application schemas for the purpose of simplifying the national data sets content and extending the detail of INSPIRE data sets were created. New XSD schemas were created according to the models. The goal of the project is to create new data sets meeting the needs of national authorities, municipalities and citizens with the full INSPIRE compatibility.
