Project overview
On 28 March 2025 at 6:20 UTC a 7.7 earthquake struck the Sagaing Region of Myanmar, with an epicentre close to Mandalay, the country's second largest city. It is the most powerful earthquake to strike Myanmar since 1912. It has resulted in more than 2,000 deaths. As of 28 March, authorities declared an emergency, and expect the death toll to rise.
**Please help to identify newly damaged buildings caused by the earthquake by comparing "Before" earthquake and "After" earthquake images to support the ongoing humanitarian efforts in the affected areas.**

Download the data
Below you'll find the data downloads for this MapSwipe project, including a GeoJSON file that can be imported into the HOT Tasking Manager for more detailed mapping of the area. If you need more information or if you have a special request related to MapSwipe data get in contact with the team at the Heidelberg Institute for Geoinformation Technology
Aggregated Results
Aggregated Results. This gives you the unfiltered MapSwipe results aggregated on the task level. This is most suited if you want to apply some custom data processing with the MapSwipe data, e.g. select only specific tasks. Check our documentation for more details. (Note that you need to unzip this .gz file before you can use it.)

HOT Tasking Manager Geometries
This dataset contains shapes that are ready to use in the HOT Tasking Manager. Currently, the geometries consist of maximum 15 MapSwipe Tasks, where at least 35% of all users indicated the presence of a building by classifying as "yes" or "maybe"
GEOJSON
19 kB
Moderate to High Agreement Yes Maybe Geometries
This dataset contains all results where at least 35% of users submitted a "yes" or "maybe" classification. The output dataset depicts the union of all selected results.
