Support to Landsat 5 and 7

Post by rafael.simao »

Hi everyone

I was wondering if there are any plans to include support for processing Landsat 5/TM and Landsat 7/ETM+ with Polymer, considering that these two combined allow for a very long time series and are part of the Landsat Collection 2. I have been trying to do this by modifying the Landsat 8 and params scripts, but have had no success so far :(

Are there any plans to support scenes from these satellites on further releases? Or any hints on how to do this by myself?

Thank you

Dear Rafael,

There is no plan to support these sensors, because they have a limited number number of spectral bands, and the applicability of Polymer in these conditions would require not only the implementation of a dedicated reader, but also an evaluation of how Polymer behaves in these restricted conditions.
The implementation of the readers require writing a module in the same way as level1_landsat8.py, providing TOA radiometry, angles, temporal information, central wavelengths for each band, etc.
Cheers, François
