Project overview
This special MapSwipe project involves looking at before and after imagery to check for the development of settlements - it uses low resolution imagery (20 times less sharp than the imagery we typically use on MapSwipe). We are not looking for individual buildings here, in fact it will not be possible to see these, instead we're looking for new clusters of buildings.
Millions of individuals living in informal refugee and IDP settlements are estimated to be missing from national surveys, yet they are the world’s most vulnerable populations - displaced and resettled due to disaster, development and/or conflict and violence. The Missing Millions research project in collaboration with Oregon State University and funded by NASA is looking to identify new and expanding informal settlements. The use of low resolution but high-frequency open Sentinel imagery in this project allows for monitoring and identification of settlements quickly on a large scale.

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"
