[Qgis-developer] Problem with GDAL_translate. REST Services, QGIS

[Randal Hale]

Do gdal service description files no longer work? I was hoping for an 
XML output.

From:
http://hub.qgis.org/wiki/17/Arcgis_rest:
1. In the QGIS Python console, run this:
|qgis.utils.iface.addRasterLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json&pretty=true","raster")|
2. Create a gdal service description file, e.g. by running this in a 
terminal:
|gdal_translate 
"http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer?f=json&pretty=true" 
s.xml -of WMS|
You can now load this file into QGIS, e.g. by drag-and-drop.

I've used it several times - this morning it wouldn't work - Unless it's 
something I'm doing wrong and I really hope it is. I thought it was odd 
using json but I was just following directions as posted.
