This project presents a custom GIS solution to aid in the production of electronic terrain and obstacle data sets (eTOD) for the world’s airports. The eTOD mandates underlie the International Civil Aviation Organization’s (ICAO) effort to modernize world air traffic control. ICAO has set a deadline of November, 2010 for nations to assemble eTOD sets for all their airports. The project client, ESRI, sought a custom eTOD solution for users, with limited GIS experience, to assess the quality of their terrain and obstacle data and plan for further data acquisition. A file geodatabase was developed to organize the user’s existing aeronautical data and manage these data for project application use. The eTOD rules establish data quality standards for four Coverage Area designations, each represented by specifically shaped and sized boundaries around airports. Methods were developed to generate these boundaries using tools assembled with ArcGIS Model Builder in ArcView. The models simultaneously select the obstacles within the generated boundaries for data quality assessment. With limited training, a user can easily organize their data, automatically generate the eTOD Coverage Areas, and produce data quality assessment reports in support of their preliminary efforts towards reaching eTOD compliance.
