Questions on georeferencing are some of the most common questions that we get in Support. These conversations range from basic how to questions all the way to questions like “Why are the buttons grayed out?”
Have you ever added a raster image to your map document only to find that some of the georeferencing tools are not available? You know you’ve done this many times in the past, but what’s different this time?
A quick test to identify any issues is to add the image to a new blank map document instead of an existing map document. If the tools are available in the new map document, then one of the reasons for the problem may be that your data frame in the existing map document is rotated. ArcMap can’t apply a double-transformation to the raster.
Here are the only functions available when the data frame is rotated:
- Update Georeferencing*
- Reset Transformation*
- Flip or Rotate functions
*Available once image has been modified.
Simply clearing the data frame rotation will activate the following functions:
- Fit to Display
- Auto Adjust
- Add Control Points
- View Link Table
