Unmasking Africa with
Data and Intelligence.
Building Africa's largest and most centralized environmental GIS database. We fuse satellite-grade observation with the lived African context to solve real geospatial challenges.
Satellite-grade
observation.
Our GIS datasets are carefully geoprocessed from NASA, ESA, USGS, HydroSHEDS, among others. These are the same data sources powering global environmental research.
Built for the
African context.
Innovation strives in Chaos. Our datasets are used to fight floods, drainage failure, air pollution, among others, directly confronting chaos with solid Innovation.
