Sažetak
Due to the unequal development of cities and drainage systems, non-compliance of the natural drainage basins and the creation of artificial basins, there is a growing demand for the rapid geodetic maps, that can be used for the preparation of project documentation of the water drainage system construction. The reason for the inability of creating geodetic maps only for a specific critical location is that the reconstruction of a single weak link violates the conditions of the infrastructure in the surrounding area. The study and the project documentation cannot be resolved within the limits of the intervention without previously established conditions of the surrounding areas. The goal of this paper is to present the results of the use of the official digital terrain model of the Republic of Croatia combined with cadastral polygon points in the preparation of project documentation for water drainage system construction. The research and the analysis will be carried out for the area of the City of Pula. Since the development in vertical sense is higher in the centre of the city compared to the parts of the city with lower development intensity, the accuracy of the model within the centre will be presented. It will also be shown, whether the model accuracy depends on the higher coverage of vegetation compared to the places with low vegetation and construction. The paper will present whether the DTM accuracy meets the requirements in areas with a small slope, where the focus is in the preparation of project documentation for water drainage system construction.
