Developement Of Digital Model Of Terrain (Dmt) Using Autocad And Surfing Software Packages

Abstract

This paper considers a problem of developing a digital model of topographic surface (terrain) which, as an empirical surface, requires a specific approach in 3D modeling. The solution is found by using two software packages: AutoCAD, used in classes of Computational Geometry, and Surfing, used as an educational tool in several subjects at the department of Survey, on the Faculty of Civil Engineering in Belgrade. We compared these two techniques of DTM development, in order to determine the advantages and deficiencies of both. Through creating different digital models and comparing the obtained results, our goal was to contribute upgrading the techniques of processing topographic surfaces, as an important segment of planning that connects Computational Geometry and Surveying
