[Qgis-user] Georeferencing Vector Files

[Springfield Harrison]

Hello Alex,

         This sounds promising, but then so did the other plug-ins.

         Where do I find the OGR2OGR functionality?  I found some 
help information referring to it but nothing about how it is accessed.

         Not sure why I would need to create the control points from 
the raster georeferencing as I already have them from fieldwork or 
other sources.  What I do need is a function or tool to rubber sheet 
the un-projected coordinate list onto a projected layer containing 
the control points.

         My CAD program is not able to do this.  I tried manually 
shifting and rotating but that is a very sketchy process at best.  My 
testing so far indicates that the transformation to UTM will require 
both scaling and rotating.

                         Thank you, Cheers . . . . . . . . Spring Harrison
