GRD Mosaic Issues

Hey everyone,

I am very new to this and I was trying to get a Mosaic of 20 GRD files of a river in Taiwan.
I’m able to to merge up to 4 horizontally but when I start merging vertically it keeps either resulting in a one height product or
giving me this message

Hopefully the image uploaded. Any help is greatly appreciated. Thanks!

@tsayduck You might want to try asking this question in GDAL chat channel irc Kiwi IRC or https://matrix.to/#/#gdal:osgeo.org or QGIS https://matrix.to/#/#qgis:osgeo.org or mailing list QGIS-User Info Page (or chat - https://matrix.to/#/#qgis:osgeo.org)

How large are your images? Can you post a screenshot of your settings, in particular of the “GDAL/OGR console call” box?
