In virtually alldeveloped countries, the needs of computerized land and geographic information systems (LIS/GIS)has given urgent impetus to computerizing cadastral maps and creating digital cadastral data bases(DCDB). This process is creating many institutional, legal, technical and administrative problems.This desire to establish DCDBs is being given increased impetus due to a new range of enablingtechnologies such as satellite position fixing (GPS), improved spatial data collection techniquessuch as digital theodolites and "soft copy" photogrammetry, as well as a vast range of newinformation and communications technological tools, thus contributing to the advancement andkeep up with the great countries. This paper presents the problem of cadastral maps. The hitherto existing cadastre, consisting ofpaper maps and land registers, is now becoming insufficient. Its shortcomings force developmentsleading to its improvement. One of the ways is the creation of a Land Information System. A digitalcadastral map is the main component of this system. The structure and information content of themap is presented, its differences from analogue maps are shown, and the process of map creation isdescribed. A digital cadastral map can be the basis for additional thematic layers, successivelyconverting it into a complex system for management of administrative units.
