The closest thing I've seen in qgsAffine plugin which should let you stretch and rotate your layer to match a better base layer, though it's by hand/vision.

Enjoy,

I don't think Qgis has vector warping tools. The Georeferencer plugin

GCPs use GDAL directly, which itself implements warping for rasters only.

I think that writing a warping plugin for vectors woudn't be too hard, but
it's not what you were looking for ;)

Hi!

We have a vector layer that has been digitized over a raster with
wrong settings (wrong pixel resolution).
Is there any way to correct the geometry of the vector layer by
defining control points with the new coordinates and apply
a warping in qgis?
