Build long time series with Landsat 8 and Sentinel 2

I am wondering how to use both Landsat-8 Time series and Sentinel 2 with iota2 to construct long time series ?

I have sample points shapefile for which I would like to extract the reflectance time series from 2014 to 2020. I need to merge Landsat 8 and S2 time series.

I found an old issues regarding the documentation (#114 (closed)) but there is no documentation. As far I understand, I need to

  • define last_step as "sampling" since I just need the reflectance for some points in a shapefile
  • define S2 mandatory information (s2_path, list_tile, s2_output_path, start_date, end_date, temporal_resolution)
  • define Landsat 8 mandatory information (l8_path, start_date, end_date, temporal_resolution)
  • define the spatial_resolution (e.g. 10 m)
  • define the sensors_data_interpolation mandatory parameter.

I also wondering if it possible to define non-overlapping temporal gap-filling features: e.g. Ask to reconstruct landsat-8 between 2015 and 2017 and S2 between 2017 and 2021 by playing with the star_date and end_date of the config file for each sensor.
