landsat coreg product

[ircwaves]

Add a product option to coregister landsat onto Sentinel-2

[ircwaves]

Earlier estimate of timing was off. Current ballpark for coregistration is over an hour.
Need to determine where/why it is taking so long. I suggest adding verbose_outs that include a time delta from the start of the process function.

Probably better to use sentinel2Data.inventory(...) here, because this fetches the file but doesn't update the database inventory: https://github.com/Applied-GeoSolutions/gips/blob/5f0dcf9d69ac16591a0ba95049dedeedd38b722f/gips/data/landsat/landsat.py#L1406-L1411

12 minutes of converting jp2 to tif:

• replace with VRT

1 hour 10 minutes for CookieCutter:

• need to look into this

(side note: we need to replace lots of stuff in the sentinel2 driver with VRTs)

[ircwaves]

For the CookieCutter, set crop=True in the call. That should make the resulting file significantly smaller.

[naterubin]

Instead of using CookieCutter at all, all relevant are gdal_merged together, which only takes a few minutes, reducing the processing of a coreg product to about 4 minutes.

And in the event that you've coregistered a product for a given tile+date previously, additional products require very minimal (seconds) of additional processing time.
