Inundated Area From 1999 To October 2013, Niger

Published on 05 Nov 2013 View Original

This map indicates small temporary water bodies, wetlands, and other humid areas as measured every 10 days between 1999 and the 31 October 2013 by SPOT satellites. Each pixel therefore indicates how many decadal (ten day) periods within the 178 month sampling period experienced some form of inundation or wetland conditions. Darker pixels indicates areas with relatively higher frequency of inundation, while lighter pixels indicate areas with less frequent inundations. The pixel with a value of 535 represent the permanent water bodies (ie lakes, rivers, and ocean), while a pixel value of 0 therefore indicates arid areas with no water ever present during the sampling period. This map is intended to provide information on the likelihood of possible inundation conditions within specific areas and based on satellite remote sensing. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR /UNOSAT
