Powerful earthquakes hit southern Turkey and Syria on 6 February 2023. These earthquakes in Turkey and Syria caused thousands of casualties and destroyed cities. Geospatial infrastructure is critical to respond to these earthquakes during rescue operations, humanitarian effort as well as planning recovery activities. Yercizenler coordinated mapping activation with the collaboration of Humanitarian OpenStreeMap team to improve open geodata infrastructure in the earthquake affected region and supporting humanitarian response in the scope of mapping.Türkiye Earthquakes Mapping Response aims to complete open map data infrastructure before and after the event in affected areas. This response is structured with following workstreams; Remote Mapping, Post-disaster Field Data Collection, Global Community Activation and Geo-data Integration. In this keynote you will have the chance to see how open data and community activation helped save lives after earthquakes, what challenges were faced and what was learnt during the Türkiye Earthquakes mapping Response effort.
