Hi Folks,

I know someone answered this before, but I can't find the e-mail where I had the directions. I want to scan a map and use the image to trace contours. I need to know how to geo refrence the map so the image's corners match there location on the Irish National Grid.

Thanks for your help.

Import into an xy location. Use i.group, i.target, i.points, i.rectify in that order

You are set after that I think.

Good luck,
Ian
