Re: [gdal-dev] Noise at the top of NOAA19 (L1B) image

Do you suggest the image itself might be corrupt? I can see the top of the image without noise if I extract the individual bands using pygac and then I create a TCI with GDAL: https://i.imgur.com/OspvQi7.png El 21/8/2024 a las 10:49, Andrew Brooks escribió: That's completely normal for data w

Re: [gdal-dev] Overview resampling generating non-existant values

For COG format, you should use -co RESAMPLING=mode. gdalwarp's -r switch only applies to the full resolution warper resampling, not the overviews. TB Le mer. 21 août 2024, 18:09, Justin Terry via gdal-dev < gdal-dev@lists.osgeo.org> a écrit : > Hi, > > > > I'm experiencing a strange issue I've ne

[gdal-dev] Overview resampling generating non-existant values

Hi, I'm experiencing a strange issue I've never seen before where certain resampling methods that should only include values in the original dataset, like mode and nearest, are adding new values in the overviews. For example, the original raster contains the following values: [0, 1, 2, 4,

Re: [gdal-dev] Noise at the top of NOAA19 (L1B) image

That's completely normal for data which has been received from satellites that do not have on-board error detection/correction such as NOAA-n (n<20) On Tue, 20 Aug 2024 at 22:05, Francisco Vicent via gdal-dev < gdal-dev@lists.osgeo.org> wrote: > Hello there, GDAL community! > > I'm experiencing s
