Geotiff visualization creates strange artifacts and does not handle correctly NaN #70
Description
Hi,
I created a series of collections where it is possible to visualise the geotiff but I'm experiencing strange behaviour in certain cases.
If you look here, for example, you can find a geotiff that is correctly displayed.
This geotiff has -999 as no data.
In other cases, my geotiff has NaN as no data value. In this case, the geotiff creates the artefacts as in this example
I tried using gdal to substitute the NaN with -999 with this command:
gdal_calc.py -A $tiff --outfile=$output_folder$output_tif_nan --calc="A*(A>0)" --NoDataValue=-999 --overwrite
and with gdalinfo it results that the image has -999 as no data but if I try using this new image it results in a black image like here
What is strange is that if I open the image with QGIS it is clear and the values are correct.
Could you please tell me if I'm doing something wrong or if it is a possible bug in the browser?
The images are all stored in an Amazon S3 bucket
