Project overview
This MapSwipe project aims to identify building footprints in the Bijni Pt-Chirang district.
In 2025, the Bengtol revenue circle in the Chirang district of Assam experienced significant flooding, particularly during the first week of June. This was part of a major wave of monsoon-driven deluges that affected over 19 districts in the state
By mapping buildings in these areas, volunteers will help create essential baseline data on settlements and infrastructure. This information will support climate resilience efforts by improving preparedness and enabling faster damage assessments and more effective response if similar floods occur again in the future

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.

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
0.3 MB
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.
