How to georeference a raster
 Georeferencing a raster
Add the layers residing in map coordinates (target data) and the raster you want to georeference.
In the table of contents, right-click a target layer and click Zoom to Layer.
From the Georeferencing toolbar, click the Layer dropdown arrow and click the raster layer you want to georeference.
Click Georeferencing and click Fit to Display.
This will display the raster in the same area as the target layers. You can also use the Shift and Rotate tools to move the raster as needed.

Click the Control Points button to add control points.
To add a link, click the mouse pointer over a known location on the raster, then over a known location on the target data.
You may find it useful to use a Magnification window to add your links in.

Add enough links for the transformation order. You need a minimum of three links for a first-order transformation, six links for a second order, and 10 links for a third order.
Click View Link Table to evaluate the transformation.
You can examine the residual error for each link and the RMS error. If you’re satisfied with the registration, you can stop entering links.

Click Georeferencing and click Update Georeferencing to save the transformation information with the raster.
This creates a new file with the same name as the raster but with an .aux file extension.

Tips
To display the Georeferencing toolbar, right-click the Tools menu, point to Toolbars, and click Georeferencing.
You can delete an unwanted link from the Link Table dialog box.
Press the Esc key to remove a link while you’re in the process of creating it.
You can permanently transform your raster after georeferencing by using the Rectify command. Click Georeferencing and click Rectify. This creates a new raster dataset in GRID, TIFF, or ERDAS IMAGINE format.
