Warp tool requires CRS of extent when no extent set

Description

Since updating to QGIS 2.16 in Ubuntu, there is a new field: CRS of raster extent. This field is mandatory even when no extent is specified. Specifying a CRS in this field, for example the same CRS as the Destination CRS, creates a -te value in the GDAL command.

When the raster extent field is blank, the Extent CRS should not be required, and no -te flag should be included in the gdalwarp command.

Should be fixed in master

#3 Updated by Evan Derickson over 7 years ago

As of 2.18.5, the GDAL warp tool will always add a -te parameter to the gdalwarp command, no matter if the user inputs something to the extent field. If the user does not select a CRS for the extent, the tool will fail with the message:

ERROR 1: Attempt to create 0x0 dataset is illegal,sizes must be larger than zero. 
Creating output file that is 0P x 0L.

The user must still designate an extent CRS to proceed. I would therefore still consider this bug still open, though its nature has changed.

agree, I must address this -te parameter.
