Project overview
The government of Karnataka has provided subsidies to farmers to build ponds for rainwater harvesting. Many farmers who have built these ponds use it for additional purpose like inland fish farming. Due to being new to fish farming the yield is not good. Having a better yield would mean better economic conditions for these farmers and also better nutrition with the increased protein intake in their diet. Hasiru Aqua is a aquaculture startup helping these farmers by providing them with services like water health monitoring and selling them fish-lings and feeds. They have helped few of these farmers to improve the fish farming yield. In order for Hasiru Aqua to support these farmers they need to know where the ponds are so that they can reach out to farmers in these 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.

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.)
