Abstract

This paper has compared the effectivenesses of different water body indices which are applied to

identify water bodies based on the MODIS data. The results show that the Combined Index of NDVI and MIR for Water

Body Identification (CIWI) is the most effective index for water body identification when the MODIS data are used.

In calculating CIWI by using the MODIS reflectance data with 0 as the distinguishing value, the constant in the

expression of CIWI is -0.85. It is also shown that the MODIS data are unsuitable for small water body

identification because their spatial resolution is not very high.
