Images to Analyse

Within the scope of this project, necessary images those are sensed and produced by Landsat 5(TM) are obtained from USGS Earth Explorer.

• Acquisition Date of Image: 11.09.2011
• WRS Path= 180
• WRS Row= 031

Normalized Difference Salinity Index(NDSI)

Normalized Difference Salinity Index is used to determine the salinity situation of soil. NDSI is calculated by the formula:

• (SWIR1-SWIR2)/(SWIR1+SWIR2) for Landsat 4-5 images.
