[GRASSLIST:507] Rubber Sheeting (or Rectification) of Vector Data

[Daniel Fuka]

Hello All,
I am having problems with a local data set. Seems as if our county started
off a digitization project sober, and ended it drunk. With this in mind,
does anyone have any advice on an easy way to rubber sheet or rectify a
vector dataset. All areas look good locally, and the center and eastern
portion of the dataset are correct. As the data goes west, (and the beers
started flowing???) the data starts getting pretty consitantly skewed. 

Is there an easy way to rectify, or rubber sheet vector data in grass that
I am missing? If not, and recommendations?

Thanks,
Daniel Fuka
