ACOLITE forum

Hi Quinten, I read the issue here: https://odnature.naturalsciences.be/remsem/acolite-forum/viewtopic.php?t=266 however can not solve my problem and since the last comments turned into another topic (i.e., cloud shadow), I open a new topic here for PlanetScope. I cloned the latest ACOLITE version fr...

Thank you very much. That's all I need.

Have a good day.

Hi Quinten, Could you please clarify the name of Rrs band and the corresponding band name of Landsat 8? It seems a bit different in wavelength between the Rrs products and the original Landsat 8 band name. From the processing notes: 2021-07-22 08:15:23: Computing surface reflectance 2021-07-22 08:15...

Yes, you are right. It is a bit different when measuring the pixel size in QGIS and SNAP. Zoom in the pixel in SNAP, we see the "sub-pixels" in one pixel

Many thanks to your feedback.

Hi Quiten, Thank you for your detail explanation. However, the Rrs_443 is still in 60 m (please see attached image). Also attached the Rrs 443 in GTiff format if you need to check the file. File Rrs_443 60 m: https://drive.google.com/file/d/1NyK5wccLB-zIf5WJ11qzO92ACBD1wZQU/view?usp=sharing Many tha...

Hi Quinten, Sorry for a late reply. I had field trips recently :D :D Yes, the exported NC format keep all bands at the spatial resolution of 10 m. Unfortunately, the exported GTiff format only keep 10 m of spatial resolution in the bands 490, 556, and 665. You designed the GTiff like that or do I mi...

Hi Quinten, I processed a Sentinel - 2 scene with the desired outputs as: ## output l2w parameters l2w_parameters=Rrs_*, a442_qaasw, a492_qaasw, a559_qaasw, a665_qaasw, bbp442_qaasw, bbp492_qaasw, bbp559_qaasw, bbp665_qaasw, kd442_qaasw, kd492_qaasw, kd559_qaasw, kd665_qaasw but there is only Rrs_* ...

Hi, Could I raise the issue of ancillary data downloading from ACOLITE? The credentials were added to /config/acolite_config.txt as guided, however ACOLITE can not automatically retrieve the ancillary data from https://urs.earthdata.nasa.gov/?

Hi Quinten, We intend to use this WV2 scene for vegetation classification (11 classes). Since we are not looking for an absolute reflectance value, the image itself may be used somehow. I will compare this corrected scene with one corrected using FLAASH in ENVI from my college. So, what do you think...

Sorry, 2 images can not attached due to their size.
