[Qgis-us-user] Shape File in Wrong Location

Good morning - my gut says it was digitized in a local grid vs something 
useful. Which means you'll probably have to re-digitize it.

There are some tools in GRASS that might help - granted I've not used 
them but v.transform might give you the chance to warp it back to the 
right location. You'd have to know a few things like the 
shift/scale/rotation to get it to where you need it to be. Which - 
hopefully it's all digitized in CAD correctly scaled.

They had an engineer provide an AutoCAD drawing several years back that have a lot of the system intact, but along with a lot of other info I don’t need. I imported the whole thing into QGIS and exported various layers I need as shapefiles. I then added the shapefiles to a QGIS project that includes an OpenStreetMap layer. Nothing showed when zoomed in to the community, so I “zoomed” out and out and finally found found the shapefiles rendered completely outside the OpenStreetMap layer (i.e. its a little rectangle) and to the right (east) also about 4-5 times the size of the entire OpenStreetMap layer showing the whole world.
