Title
Satellite detected water extent in Manja, Morombe & Ankazoabo Districts, Madagascar as of 03 January 2024
Description
**UNOSAT code: TC20240102MDG, GDACS ID: 1001040** This map illustrates cumulative satellite-detected water extent in Manja, Morombe & Ankazoabo Districts, Madagascar as of 03 January 2024 as observed from a Sentinel-1 image acquired on 03 January 2024 at 05:36 local time. Within the cloud free analysed area of about 5,500 km², a total of about 670 km² of lands appear to be affected with flood waters. Based on Worldpop population data and the detected surface waters, about 18,000 people are potentially exposed or living close to flooded areas. 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.
