Flood waters were identified through an analysis of ENVISAT ASAR satellite data recorded on 17 February 2011 with a medium degree of confidence. The pre-flood water extent was extracted from ENVISAT ASAR data collected on 19 February 2004. This flood detection is a preliminary analysis & has not yet been validated in the field. It is possible that flood waters have been significantly underestimated in certain vegetated areas along the Limpopo and Incomati rivers because of water signature confusion in the radar data. Flood waters shown in this map thus likely represent minimum estimates. The rainfall data was derived from the Tropical Rainfall Monitoring Mission (TRMM) precipitation dataset at a spatial resolution of approximately 25km for this region. It is possible that precipitation levels may have been underestimated for local areas, and is not a substitute for ground station measurements. The depiction and use of boundaries, geographic names and related data shown here are not warranted to be error-free nor do they imply official endorsement or acceptance by the United Nations. This map was produced by the United Nations Institute for Training and Research (UNITAR) Operational Satellite Applications Program (UNOSAT). UNOSAT provides satellite imagery and related geographic information to UN humanitarian and development agencies and their implementing partners.
