In the face of disasters, timely access to accurate geospatial data is critical for effective response efforts. This presentation explores the pivotal role of OpenAerialMap (OAM) in enhancing open maps and facilitating swift disaster response. We delve into the evolution of OAM, from its inception to the latest advancements, highlighting its use as a comprehensive repository of openly licensed satellite and UAV imagery. The session will showcase OAM Mosaic Map's features. Join us to discover how OAM, through collaboration with the Humanitarian OpenStreetMap Team, is shaping the future of open maps and geospatial response in times of crisis.
