Obstacle Evaluation Solution (OES)
OES provides a web service with the national Aeronautical Information Services which is in charge of the management, collection, organisation and distribution of aeronautical information.
OES is used to evaluate the potential impact of infrastructure modifications on aerial navigation and provides the necessary data to properly use the associated information (OLS and EZS), in accordance with Appendix 15 of the OACI and in accordance with local regulations (such as Eurocontrol in Europe).
