Digitizing large volumes of historic information and interpretation by OCR
Wouters, Rik
Since a long time the Dutch Land Registry, Cadastre and Mapping Agency (in short Kadaster) delivers digital information to customers. Already in the early 90-ties information to public notaries was disseminated through IBM-global network. In 2002 Kadaster opened the internet shop KOL (Kadaster-on-line), through which legal ownership information on real estate was provided. At present Kadaster is scanning old paper documents: field sketches and historic cadastre maps. In total some 9 million documents are scanned. In 2010 this kind of historical information can be made available through the internet. An other project deals with the retrieval of information concerning encumbrances, restrictions, servitudes, and the like. By means of text recognition tools more then 95 of this information is extracted form old deeds. Also this information is available on the internet. The paper describes what procedures, approach and techniques have been used to make a next step in e-services provided by Kadaster.
