[gdal-dev] Georeferencing vector layers

[Karen M]

Hi All,

I'm trying to use Gdal to replicate the ArcGIS Rubbersheet Spatial
Adjustment (Transform) capability for georeferencing vector layers.  I've
been trying to do this using ogr2ogr with the thin plate spline option and
with GCPs to define the start/end points for the "links" .  In ArcGIS you
also have the option to use "anchor points" to hold features in place that
you don't want to move as part of the georeferencing.  I've tried using
GCPs with the same point for the ungeoreferenced and georeferenced points
to replicate the anchors.

This methodology is giving me some very strange results and I was wondering
if anyone has any suggestions for a better way to do this.

Thanks in advance for your help.
