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).
Head to the ODC Sandbox (click here) and login with GitHub Open Authorization.
Open the /examples folder.
Open and run the /examples/Landing_Page.ipynb notebook block by block.
In block , use the map interface to draw a small area of interest, and select a time frame.
Click "Query Cube" and review the number of tiles that will be accessed. Less than 100 will run quickly.
Run block , 'band_indices_aws_landsat8', click on the NDBI button, and calculate NDBI for anywhere inside your previous bounds.
