Satellite Detected Surface Waters Extent and Evolution around Chimuara and Caia, Zambezia province, Mozambique (Imagery analysis: 05 February 2017 | Published 6 February 2017 | Version 1.0)


This map illustrates satellite-detected flood waters around Chimuara city, Zambezia province, Mozambique as observed from the Radarsat-2 image acquired on 05 February 2017 and Sentinel-1 image acquired on11 December 2014. A relative stability of surface water extent was observed in the 05 February 2017 image compared to the 11 December 2014 image. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks and within built-up urban areas because of the special characteristics of the satellite data used. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.
