摘要：Project of building country wide DTM for Serbia and Montenegro is coming to its final phase. The project is based on scanning and vectorization of contours from existing 1:25000 topographic maps. Supplementing contour data with additional data sets available on map layers, such as hydrography and spot heights, is also planned within the project. Procedures and software tools for data acquisition, verification and processing were developed and implemented. Special attention was dedicated to the problem of high quality terrain surface modeling using contour data and all the other available information. The main concern was reconstruction and usage of all implicit information contained in contour data. Procedures based on TIN data structure were designed and implemented. Also, procedures and initial tests for the evaluation of the DTM quality are designed and started within the project. The paper reviews applied procedures, algorithms , current project status and some results
