Global Mapper's rectify function

Recommended Posts

I've been using Zero's GM tut on road shapes and rectifying..........

loaded up the png and shape file in GM went into rectify, added 20 points and applied

this is what I get

It's like it just moved the 20 points and left the rest of the shapefile where it was. Did I miss a step? Has

anybody else run into this problem?

**Nevermind, got it sorted out. :)

I didn't realize that I also had a box shape drawn around the outside of my shapefile, so it

was causing the stretch effect. Once I removed the box and added a few more points, it lined up.

I did go back and ended up adding about 125 points of reference to get the shape to line up close to the actual road.
