Title
Satellite detected water extent in Manakara Atsimo District, Vatovavy Fitovinany Region, Madagascar as of 05 January 2024
Description
**UNOSAT code: TC20240102MDG, GDACS ID: 1001040** This map illustrates satellite-detected water extent in Manakara Atsimo District, Vatovavy Fitovinany Region as observed from a Sentinel-1 image acquired on 05 January 2024 at 05:20 local time. Within the extent of this map of about 300 km², a total of about 20 km² of lands appear to be affected with flood waters. Based on Worldpop population data and the detected surface waters, about 6,300 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.
