Tomnod Teams up with UC San Francisco

July 22, 2015 - 20:53 -- William Shaw

Tomnod has teamed up with the University of California San Francisco's Malaria Elimination Initiative to develop a population map of Swaziland to assist in planning and implementing malaria elimination activities.

Tomnod uses DigitalGlobe satellite imagery to engage online volunteers to scan small portions of a large area. The volunteers scan the imagery and mark locations of interest to that particular survey. In this case the survey is looking for villages across Swaziland. When buildings are spotted by a volunteer in a polygon, that polygon is marked.

Multiple volunteers are assigned the same area to increase the accuracy of the marking and cut down on ambiguous or inaccurate results.

This particular search is labelled "Mapping Swaziland" and the URL is : http://www.tomnod.com/campaign/swaziland_validation_2015.
