You'll need some GIS software to do this, as well as some reference data. The actual process will depend on the actual software you have, but in general it should be something like this:
- Import your reference data
- Import the data you got out of Corel Draw
- Identify control points (these are points that you can find in the Corel Draw data as well as in the reference data)

Some things to keep in mind are the projection (it's highly recommended that your reference data is in the same projection as your Corel Draw data) and the number of control points (the more you pick, the better the result is going to be).

Hope this helps.

This can be accomplished in ArcMap using the Spatial Adjust toolbar.

You can also do this in MapInfo using the Register Vector tool.
