Georeferencing Part 1

Georeferencing Part 1
Using the View drop down and going to Toolbars- Georeferencing toolbar. This allows us to assign real world coordinates to our raster data, to a image that does not have real world coordinates, using control points.
Starting in the display window layer of our real world coordinates we ‘fit to display’ our new data to display an overlap. Here we can reference non real world to real world starting with the unknown using control points. You have to use more control points if your map is not very accurate.
We create a world file by Updating Georeferencing
