I have elevation data with .rrd extension. WHat do I do to load it on ArcMap? Thanks
RRD files are "reduced resolution display" files, or in more basic terms, pyramid files that are built to improve performance when viewing imagery at different scales. One doesn't have to load them separately, they should automatically load into ArcMap/ArcCatalog when you load the imagery that they were created from.
ArcGIS Help (10.2, 10.2.1, and 10.2.2)

Thanks Chris Donohue. That explains it. It looks like I am lacking the imagery and I thought rrd was another format for the imagery. I will re-download the data
