Abstract
It is widely accepted that cadastral data are one of the main pillars of national information systems. A good number of administrative and legal services are provided on the basis of cadastral plans and land registry. One of the geographic data layers used in INSPIRE (Infrastructure for Spatial Information in the European Union) is that of cadastre or land registry. It has recently become a common practice to use open source and interoperability technologies supported by XML (Extensible Markup Language). The Geography Markup Language (GML 3.2.1) is the XML grammar developed by the Open Geospatial Consortium (OGC) and supported by INSPIRE for encoding spatial and non-spatial data. The storage of available land registry and cadastral information only does not meet the multiple needs arising today. This paper outlines the development of a GML application schema for setting up cadastral information systems including real estate valuation and geological information.
