The inventory is a nationwide listing of known publicly
available high-accuracy topographic and bathymetric source elevation data for
the United States and its territories. The inventory provides a single resource
for information about all known completed and in-progress broad-area public
domain elevation data.
The United States Interagency Elevation Inventory raises
awareness of and increases access to existing elevation data, thereby reducing
data duplication efforts. It helps to identify data gaps and informs and
encourages collaboration on future data collection efforts. The inventory
displays data set boundaries and provides information about the elevation data
but does not host the data itself. If available, links to access the data,
metadata, and reports are included.
The information in the inventory may also
be accessed via map services, and the terrestrial information is available as a
GIS layer for download. The United States Interagency Elevation Inventory is a
dynamic catalogue maintained by a partnership of federal agencies and supports
the federal elevation theme.
