I have DEMs with "-3.40282e+38" values that are supposed to be the NoData values. However, if the rasters are loaded into QGIS (3.4.11), the value can not get assigned with "add additional no data value" via the transparency tab.
When this value is assigned with
gdal_translate -a_nodata -3.40282e+38 input.tif output.tif the output.tif shows this value as NoData but QGIS still does not recognize it.
However, if the NoData value is computed in the tif properties in ArcCatalog and then exportet as a new tif, the assigned NoData value of the exported tif is recognized in QGIS.
How can I assign such large float values as NoData in QGIS (or GDAL)?
I am using QGIS 3.4.11 LTR on a Linux Mint 19.2 operating system. Edit: GDAL version 2.2.3 is used
