Urbanization Detection Using NDBI


Urbanization, or built up areas, can be indicated by the relative proportions of SWIR and NIR bands.

NDBI is a common index for detecting urbanization where NDBI = (SWIR1-NIR) / (SWIR1+NIR).



  1. Head to the ODC Sandbox (click here) and login with GitHub Open Authorization.

  2. Open the /examples folder.

  3. Open and run the /examples/Landing_Page.ipynb notebook block by block.

  4. In block [2], use the map interface to draw a small area of interest, and select a time frame.

  5. Click "Query Cube" and review the number of tiles that will be accessed. Less than 100 will run quickly.

  6. Run block [3], 'band_indices_aws_landsat8', click on the NDBI button, and calculate NDBI for anywhere inside your previous bounds.
