010160608 - Ebrar HİÇYILMAZ

Within the scope of this project, a baseline has been created for the determination of watery regions using NDWI (Normalized Difference Water Index). This index was also used to examine the changes in water bodies such as floods. In this Project some libraries imported. These are;

• numpy
• rasterio
• matplotlib
• notebook

  import rasterio
  from rasterio import plot
  import matplotlib.pyplot as plt
  import numpy as np
  %matplotlib inline

The NDWI Formula is shown below:

NDWI=(Band3-Band5)/(Band3+Band5)

Band 3=Green , Band 5=NIR

Inputs

Landsat 8 satellite image for B3(Green)

Landsat 8 satellite image for B5(NIR)

Outputs

ndwi_ebrar_010160608

Used index in project

Normalized Difference Water Index (NDWI)
