Upload .ers file

@newexco-kv please attach/link a sample

Here you go... Unfortunately could only post through a zip folder. Lachlan_SRTM3.zip

@newexco-kv I cannot load this dataset on Windows and Linux


gdalinfo Desktop/Lachlan_SRTM3.ers 
ERROR 4: `Desktop/Lachlan_SRTM3.ers' not recognized as a supported file format.
gdalinfo failed - unable to open 'Desktop/Lachlan_SRTM3.ers'.

but support for this format is evailable by default on GDAL

https://gdal.org/drivers/raster/index.html

so maybe the attachment is corrupted?

@newexco-kv in fact the file only contains

Maybe try these two files together?

Maybe try these two files together?

the dataset has no CRS

gdalinfo Lachlan_SRTM3.ers 
Driver: ERS/ERMapper .ers Labelled
Files: Lachlan_SRTM3.ers
       Lachlan_SRTM3
Size is 2079, 2487
Origin = (499905.000000000000000,6348825.000000000000000)
Pixel Size = (90.000000000000000,-90.000000000000000)
Corner Coordinates:

Lower Left  (  499905.000, 6124995.000) 
Upper Right (  687015.000, 6348825.000) 
Lower Right (  687015.000, 6124995.000)

Band 1 Block=2079x1 Type=Float32, ColorInterp=Undefined
  NoData Value=-999999

when you add it in QGIS you must specify the correct CRS manually (in the layer properties, not the project ones).
