The Data Source Index map shows areas which have been updated for all resolutions of the NED and is viewable at the NED Data Source Index within The National Map Viewer. Spatial metadata shapefiles showing the updated areas for each resolution are also available for download from the NED Metadata download page. Once the customer identifies a specific area of interest that has been updated, the data can be acquired through the USGS The National Map Viewer or through a bulk data request (send e-mail to firstname.lastname@example.org for more information on bulk data delivery).
