This project presents a custom-built GIS solution to assist in the production of obstruction identification surfaces (OIS) for the world’s airports. OIS is one of the key elements in providing a safe environment for air travel as many airports process a huge number of flight operations every day. The Federal Aviation Administration (FAA) and the International Civil Aviation Organization (ICAO) have put great effort into improving world air safety. FAA published Federal Aviation Regulations (FAR) and ICAO published Annexes. These regulations and annexes govern all aviation activities in order to improve the safety of air travel. In particular, a complete OIS specification is described in both regulations and annexes.

The project client, ESRI Aeronautical Solution, sought a custom-built GIS solution for users to generate the OIS in an effective way and to plan for further obstacle analysis. A file geodatabase was developed to both manage the aeronautical data and store the generated OIS feature data. A geoprocessing tool was developed to generate the OIS combined with the required aeronautical data and OIS specifications from FAA and ICAO. With the help of this innovative GIS solution, users can easily generate the OIS in seconds and maintain them in a more globalized and generalized format, thereby supporting their preliminary efforts towards creating a safer air travel environment.
