Development of cadastral metadata service (cadastral metadata database)
Cetl, Vlado, Miodrag Roic and Mario Mader
Cadastre as the large-scale spatial data is the basis of spatial data infrastructure. This is illustrated by various countries which have the cadastre as part of the basic spatial data set. Coordinated management is of special importance in the case of cadastral data, since their processing is significantly more expensive than with any other type of data. One of the most efficient tools for managing spatial data in digital and analog form is metadata. Digitization of the cadastral data in Croatia has been going on for a longer period of time. Its dynamics is closely linked to the development of computer technologies. The descriptive (alphanumerical) part of the data was digitized first, resulting in the cadastral records databases, and the introduction of the CAD program and first digitizers led to digitization of the technical (collection of map sheets) data. The cadastral records are mostly in digital form, while digitization of the cadastral maps is still going on. The result of new cadastral surveying, which have been intensified over the last few years, is a digital cadastre. This paper describes the approach to the records and the transformation of the Land Cadastre into a Real Estate Cadastre, as well as the development of accompanying services. The existing state and types of the cadastral data in Croatia were analyzed, and the standard for metadata was chosen. Based on the standard, a prototype of the cadastral meta-database was created and developed, in order to monitor and manage transformation of the Land Cadastre into a Real Estate Cadastre. The paper describes the systematic computer watch of the transformation and the access granted to a wider user group through the metadata system. The service provides insight into the current state, and various dynamic analyses. These facilitate project planning and cost assessment.
