Entering specific x,y coordinates when georeferencing
Steps:
-
In ArcMap, add the layers residing in map coordinates and the raster dataset you want to georeference.
Adding the data with the map coordinate system first is a good workflow so that you do not need to set the data frame coordinate system.
If you do not have a dataset with map coordinates, then you must set the data frame coordinate system before continuing.
- To display the Georeferencing toolbar, click the Customize menu, point to Toolbars, then click Georeferencing.
- In the table of contents, right-click a target layer (the referenced dataset) and click Zoom to Layer.
-
Click the View Link Table button
on the Georeferencing toolbar.
-
Click the Add Control Points tool
.
-
Click a known location in the unreferenced image to add the first coordinate in the link.
Tip:
Press ESC to remove a link while you're in the middle of creating it. - Right-click the image and click Input X and Y.
- Type the reference coordinates on the Enter Coordinates dialog box.
- Click OK.

You can delete an unwanted link from the Link Table dialog box.

You can permanently transform your raster dataset after georeferencing by using the Rectify command; click Georeferencing and click Rectify or use the Warp tool.
