ABSTRACT
The article presents a computational model to conform an aerodrome geometry to the ICAO Annex 14 standards. These standards impose geometric characteristics to runways, taxiways and aprons, as well as protection surfaces free of interferences according to the project aircraft. The model generates a KML file that can be read in a virtual globe such as Google Earth or in a GIS desktop as QGIS. It encompasses both CAD and GIS routines written in Python language. It allows automatic analysis of possible aerodrome geometry conflicts. Model functionality has been verified for both hypothetic and real world instances. The paper shows results of its application to the Viracopos Airport in Campinas, Brazil (SBKP). A DTM (Digital Terrain Model) of the SBKP site was achieved with subsequent generation of the runway and of the associated OFZ (Obstacle Free Zone) surfaces using SRTM (Shuttle Radar Topography Mission) data.
