Hi,
I have a geological map in a pair of files called USGS.tif and
USGS.tif.aux.xml
The XML seems to have ground control points (<SourceGCPs>) and a geographic
coordinate system (<SpatialReference>)
GDAL .aux.xml files do no have <SourceGCPs> or <SpatialReference> elements,
so it looks like this .aux.xml file is a USGS specific one (yikes!)
An .aux.xml file with <SourceGCPs> and <SpatialReference> elements
has come up before, as output from ArcGIS; see
http://osgeo-org.1560.x6.nabble.com/gdal-dev-convert-tif-tfwx-aux-xml-to-a-geotiff-td4981730.html#a4982138
The names understood by GDAL are <GCPList> and the SRS is stored
as a Projection attribute of <GCPList>
