Ben / Howard,

First, I'm not sure that GeoTIFF even has a mechanism to represent
geocentric coordinate systems.  Second, if it did, OGRSpatialReference
and GDAL don't support them so there would be no translation get from
the WKT to geotiff keys.

I think we will need to depend on the WKT VLR in LAS to represent
geocentric coordinates though I will look into geotiff tags too.

I'm starting on GEOCCS support this afternoon.

Best regards,
