Improvement of the exchange format of the digital cadastral plan

Abstract. The digital cadastral plan as a collective graphic representation of data on cadastral parcels, buildings, methods of use and addresses is created with CAD tools in DXF exchange format. The content, form and method of creating a digital cadastral plan is defined by regulations and specifications. Maintenance and implementation of changes to the digital cadastral plan takes place in the spatial database of the Joint Information System of Land Registry and Cadastre. To migrate the data of the digital cadastral plan to the spatial database, the shapefile exchange format is used, so it is necessary to convert the digital cadastral plan from DXF to the shapefile exchange format beforehand. In this paper, the compatibility of the data structure of exchange formats and the conditions and limitations in fulfilling the domain consistency and topological consistency for the simplified maintenance of all geometric and attribute relationships on the digital cadastral plan were considered.
