sentinel-2 acolite products appear to process the wrong tile #438

Open ra-tolson opened 6 years ago

ra-tolson commented 6 years ago

It looks like there's an off-by-one error in the acolite products, regardless of whether or not the limit=lat,lon,lat,lon optimization is in place: I told it to produce acolite products for 17TKG but it produced them for TLG, pretty much exactly aligned with the wrong tile one step to the East; in the attached, the dark red area is the intended tile and band 3 of the associated asset, while the black area to the right is the erroneous product; the date for the scene is 2015-226. Similar bad behavior was observed for 2015-216, except the wrong tile was one step to the West.

It'd be a good idea to test non-acolite products, and new-style assets too both with acolite and non-acolite products, to see if they misbehave in the same way.

@ags-tolson do you have a branch pushed where you implemented the limit=lat,lon,lat,lon business?

Nevermind, I found it: acolite-roi-for-s2
