Mosaic Creation Using the Geomedian Product

Documentation

Masks clouds from imagery using the median valued cloud-free pixels in the time series while maintaining the spectral band relationships.

 

This algorithm was developed by Geoscience Australia and produces excellent cloud-filtered mosaic products for further analysis.

Tutorial

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

  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. Review the number of tiles that will be downloaded and click "Query Cube". Less than 100 will run quickly.
  6. Run block [3], 'band_indices_aws_landsat8', and calculate the median for a small region inside your previous bounds.
