Problem: The georeferencing toolbar is inactive or 'grayed out'

Description

All of the tools and menu options in the Georeferencing toolbar are 'grayed out' even though there is a raster layer in the data frame.

An image of an inactive Georeferencing toolbar, despite the raster added to the map.

Cause

This issue can occur in any version of ArcMap. Assuming there is a raster layer in the data frame, some of the causes include:

  • The raster dataset has a defined projection and is being projected on the fly. ArcMap cannot apply a double-transformation to the raster.
  • The data frame is rotated. ArcMap cannot apply a double-transformation to the raster.
  • The raster was added to the data frame as a graphic object (via Insert > Picture). Graphic objects are not listed in the Table of Contents.
  • The normal.mxt is corrupt.
  • If using ArcGIS 9.0, the name of the coordinate system of the raster may be different from that of the data frame. This is a known issue in ArcGIS 9.0.

Solution or Workaround

To activate the Georeferencing toolbar, use one of the following solutions.

  • Verify the raster coordinate system
    Right-click the map and open the Data Frame Properties. Under Coordinate System, expand the Layers folder > coordinate system, click the name of the raster layer, and click OK. Or, remove any layers with differing datums from the data frame / map. Additional layers can be added to the map after the georeferencing workflows are complete.

    Open the Coordinate System tab in Data Frame Properties, open Layers folder, open coordinate system, select raster file
     
  • Set Data Frame rotation back to 0
    From the data frame toolbar, change the rotation angle to 0. Then georeference the raster. If the data frame must be rotated, use the Rectify option to use a georeferenced version of the raster in the map document.
     
  • Use the Add Data dialog
    To georeference an image in ArcMap, the image must be added as data through the Add Data dialog. Images inserted into the map as pictures cannot be georeferenced because pictures are read as graphic objects and not GIS data. Graphic objects cannot be related to actual data in real-world coordinate space.
     
  • Normal.mxt
    Navigate to the Normal.mxt and rename it. Restart ArcMap. Please note that this removes any changes or customization to the ArcMap interface, but may grant access to the Georeferencing toolbar.
     
  • Wrong Name
    There is a known issue in ArcGIS 9.0 that causes some rasters to appear to ArcGIS as being projected on the fly, when they are not. This happens when the coordinate system of the raster and the dataframe are a State Plane coordinate system that uses feet as the liner unit. The optimal workaround is to change the coordinate system to that of the raster by selecting the coordinate system of the raster in the data frame properties dialog.
