In this tutorial, you are going to learn how to calculate Normalized Difference Vegetative Index to know the level of vegetation in your area. Furthermore, Normalized Difference Buildup Index indicates the urbanization trends with the help of buildup index. In both formulas Raster Calculator tool has been utilized and indicates the values from +1 to -1. Moreover for both processes Landsat Images has been used.

In Landsat 4-7, NDVI = (Band 4 – Band 3) / (Band 4 + Band 3).
In Landsat 8,  NDVI = (Band 5 – Band 4) / (Band 5 + Band 4).

For Landsat 7 data, NDBI = (Band 5 – Band 4) / (Band 5 + Band 4)

For Landsat 8 data, NDBI = (Band 6 – Band 5) / (Band 6 + Band 5)
