GIS data exchange problems, solutions

Abstract

The present situation in Hungary in the field of GIS data exchange is introduced in this paper. Most of the data exchanges concentrate on map data (graphical data) without attributes. The new Hungarian standard DAT1 (MSz 7772-1) has changed the situation. It involves map, topology and attribute data as well and is the official data exchange format for Land Offices. The new standard probably effects most of the GIS community as the existing digital maps should be converted to DAT1 data exchange format. A solution is given in this paper. Finally the demand of a more general data exchange format is discussed.
