Title
Satellite detected water extent over Sambava and Vohemar Districts, Sava Region, Madagascar as of 01 April 2024
Description
**UNOSAT code: TC20240328MDG, GDACS ID: 1001057** This map illustrates satellite-detected water extent in Sambava and Vohemar Districts, Sava Region, Madagascar as observed from a TanDEM-X satellite image acquired on 01 April 2024 at 18:09 local time (15:09 UTC). Within the analysed area of about 850 km², a total of about 10 km² of lands appear to be affected with flood waters. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT). Important note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to backscattering properties of the radar signal.
