A computer system for semi-automatic detection of specific 2-D objects in digital images of cartographic maps is presentad. The system design combines image analysis methods with computer graphics and data base technologies. The purpose of this application system is to speed up the work of human specialist, to increase its efficiency and to transform cartographic maps into a symbolic, vector-based shape, i. e. to represent them in a general purpose data base. The system consists of three main modules: image analysis, graphic editor and data base administration. Up to now the object types being detected are: roads, cities, textured areas and some characteristic signs.
