SCRAMJET is an online tool that allows business travellers to connect and plan to meet in any of the airports included in their trip. To successfully deliver, SCRAMJET needs accurate and up-to-date worldwide airport mapping information. This paper describes an assessment of the use of Earth Observation (EO) products, in particular the Sentinel program, for improving airport mapping and monitoring its changes. The first step is to verify the data availability of Sentinel-1 and Sentinel-2 at a global scale, and then evaluate its adequacy for airport mapping. For monitoring airport changes, the analysis tested multispectral change detection methods and interferometry processing techniques. The main conclusion was that the acquisition frequency of both Sentinels is a great benefit to assure up-to-date information at a global scale. The recommended approach for a target of 200 airports is to do the airport mapping, assisted by Sentinels data for validation and improvements, and monitoring changes by integrating a Sentinel-2 change detection chain (using NIR/SWIR bands), in parallel with OpenstreetMap change detection processing.
