Does anyone have a solution on how to add the legend from a raster catalog?
It does not show up, either in version 10.1 or 10.2.1. It only shows the name "Legend".

I'm not entirely clear on what you are trying to do. Do you want a legend that lists the rasters in the catalog, one that just shows the raster catalog layer, or one that shows value ranges/classification that is common to all rasters in the catalog?
This ESRI Knowledge Base article covers getting the catalog layer to show in the legend.
This article assumes that the legend has already been created and exists in the layout, and is a workaround for the Legend Wizard which does not allow for this modification.
- Select the legend item in the layout and right click it.
- Select Properties from the context menu.
- Select the Items tab.
- Right click the raster catalog name in the Legend Items list.
- Select Properties.
- Select the General tab.
- Select Show Item Name.
- Select OK in the Legend Item Properties.
- Select OK in the Legend Properties.
To show the value ranges/classification in a legend, this ERSI forum post has a workaround that selects one example raster to create and show a legend that applies to all rasters in the catalog. It relies on all of those rasters having a common classification scale. There is also an ArcGIS Idea to add that functionality natively into the program for raster catalogs.
