This map illustrates satellite-detected areas of standing water observed on Mahe Island, Seychelles, in 12 separate GeoEye-1 images collected on 5 February, 13 February, and 16 February 2013. Though these images were very cloudy UNITAR/UNOSAT reviewed them all for indications of standing water and also produced a cumulative cloud mask to indicate which portions of the island were completely cloud obscured. A total of 28 separate standing water bodies were identified, totalling 41,025 square meters and averaging 1,465 square meters in size.
