Hi there,

I want to extract open water surface's using Xu's (2006) MNDWI.

Essentially, for Landsat 8, I have done the TOA correction, this was followed by the MNDWI calculation- using the Ratser Math tool. Everything worked fine, until I got to the point where I needed to extract the cells containing water (i.e. cells with the value >0). To extract the water, I used the Extract by Attribute tool. The results turned out blank. I have no idea what I'm doing wrong.

Please help.

Thanks.

Faeeza
