<p>Hi Grant:</p>
<p>Based on the other comments, I tested a shapefile and the
following GDAL command works</p>
<p>gdal_contour -b 1 -a ELEV -i 10.0 -f "ESRI Shapefile"
"K:/Work2/McCallum Environmental/Wedgeport/Land Clearing/CHM
Clearing.sdat" K:/Temp/contour_test.shp</p>
<p>The only difference is that in your example you have
/vsimem/xxx.tif. There are no double quotes so I do not know if
you are using a path variable or similar. I would try an actual
path to the tif dem file.</p>
