'Singleband gray' render where 'No-Data' #275

Closed shapley closed 10 months ago

shapley commented 11 months ago

Hi,

Some bands are imported with a 'Min' value of '-3.40282e+38' (No-Data). If I change the value in QGIS Properties... > Symbology to '0.0001' the band is displayed. My question is whether this is a QGIS 'no value' symbol error and if so is this the correct action to take to give a min/max values to the imported bands (sentinel-2) in my case or should I re-download again?

Hi @shapley , it is an issue related to the NoData value of the raster. It is correct to set the minimum value for the visualization. It shouldn't affect classifications however.

Thank you for explaining that.
