Abstract

This paper describes the basic logical data model from the central geospatial database (CGD) which is applicable to the structure of a digital topographic map of the largest scale – 1:25,000 made in the Military Geographical Institute (MGI), Belgrade, Serbia. CGD analysis of the road infrastructure quality, done according to the ISO 19157 standard, led to a layering of elements and sub-elements of quality which were analysed separately. ISO 19157 standard defines a procedure of quality assessment which depicts the results of the analysis for each element.

Key words: Geospatial database, digital topographic map, road infrastructure, data quality
