Abstract

Data from official statistics always have a spatial reference, often given by an administrative unit which the data are related to. Therefore statistical offices are concerned by INSPIRE, the more so as the theme “population distribution – demography” refers to one of the classical tasks of official statistics. At the same time as regards to data modeling this theme defines the prototype for official statistics. It is recommended to model data from any other statistical domain to the pattern of this prototype. Besides data on demography the official statistics of Germany currently provides data on buildings and housing as well as data of education, health and social statistics for INSPIRE. The theme “statistical units”, which for statistical purposes extends “administrative units”, takes a special role. On this issue the official statistics cooperates with the National Mapping and Cadastral Agency. The statistical offices of the federation and the federal states have decided, to tackle the challenges of INSPIRE in common. The implementation is based on the following principles: - Data supply for INSPIRE is completely integrated within data supply for the German SDI (GDI-DE), whose architecture takes account of INSPIRE. - The INSPIRE discovery service is centrally realised by the spatial data catalogue of the GDI-DE. - The information databases GENESIS-Online and Regional Database (RDB) are the primary data sources for the publication of regional statistics. Each so-called publicised table provided by these databases is defined as a spatial data set. Selected tables from the RDB are classified as INSPIRE relevant. - View and download services as well as metadata on data and services are in principle generated for each publicised table in a generic way. The metadata are provided in a daily update for the periodic transfer into the central spatial data catalogue of the GDI-DE. A web-based map application for the cartographic visualisation of GENESIS-data has already been in use at the FSO since 2010. This technology was adopted for the delivery of view services in 2013. To fulfill the performance-requirements of INSPIRE the necessary resources are preprocessed and weekly checked for actuality. Download services are realised as pre-defined atom feeds in a daily update. The name spaces defined for official statistics are recorded within a registry, run by the GDI-DE, supplying also a re-direct functionality for standardised and stable URIs.
