Questions & Answers

There is currently no mechanism to do this, every scene gets used. We will certainly be adding methods for filtering scenes in the future.

The main benefits of Spaceborne for InSAR vs. Airborne are:

  1. There are more studies and validations for spaceborne
  2. Satellites are more stable than airplanes so there are less errors in the measurements
  3. Spaceborne has a larger footprint so you can cover a larger area
  4. Satellite is more readily available and cost effective (for example Sentinel-1 data is free)

Yes. It will be available shortly on https://sdk.up42.com/examples

UP42 does not have a program for academic institutions currently but would be happy to discuss it on a case-by-case basis. 

It depends on the area of interest and how many Sentinel pairs are included in your stack. For example, for a very large AOI of around 18,000km2, the computational part of the notebook can take around 4 hours to run.

For our UP42 job we don’t want to overload users with options because we are marketing and designing this for use by non-experts. For more experienced users, we recommend¬† investigating our CATALYST Professional package, which has both DInSAR and PSI workflows and provides the flexibility to play with many different parameters.
