Solving the Situation of Airport Bled by Digital Terrain Modeling Using the Software Package Rinoceros

Abstract

In the paper, we conducted an examination of topographical conditions of the airport Bled location, using the digital terrain modeling. A detailed analysis of the ambience around the airport is done in relation to natural and artificial obstacles (already built facilities). The ambience is defined by the imaginary surfaces (the taxiways, takeoff surface, the access surface, the internal horizontal surface, conical surface and transitional surface of the takeoff-landing track) through which can not or should not penetrate obstacles. Using the software package Rhinoceros, we modeled out the terrain at the foot of the mountain massif of the Savinjske Alps and the imaginary surfaces of the airport object, whereat possible obstacles were found. This method of 3D modeling gives a better visualization (display conditions on the ground) than previously applied methods of horizontal projection (2D) and methods of cross and transverse profiles
