Locations of small-scale diamond and gold dredges detected using Synthetic Aperture Radar on the Kadéï (Sangha) River, Central African Republic
February 9, 2023
This data release catalogs the locations of small-scale diamond and gold mining dredges on the Kadéï (Sangha) River, Central African Republic from the years 2015 to 2019. The Kadéï river flows through the Nola prefecture in the CAR and is known to host placer diamond deposits. The dataset was developed through visual interpretation of 387 Synthetic Aperture Radar (SAR) scenes. The point shapefile contains 1,747 locations of vessels, identified by type as either a dredge, idle vessel, or ferry.

Detection and monitoring of small-scale diamond and gold mining dredges using synthetic aperture radar on the Kadéï (Sangha) River, Central African Republic
Diamond and gold mining has been practiced by artisanal miners in the Central African Republic (CAR) for decades. The recent introduction of riverine dredges indicates a transition from artisanal/manual digging and sorting techniques to small-scale mining methods. This study implements a remote sensing analysis of Synthetic Aperture Radar (SAR) data to map gold and diamond dredges operating on the
