Exploring the US Interagency Elevation Inventory

The US Interagency Elevation Inventory offers the ability to display and download topographic and bathymetric data for the USA.  A collaborative effort from NOAA, USGS, and FEMA, the resource contains DEM, Lidar, IFSAR, hydrographic surveys, and multibeam and Lidar bathymetric data.

The site hosts have done a decent job populating the metadata, including vertical accuracy, point spacing, and data collection, and the inventory contains a good variety of data types and formats.  To get started, visit the link above and then “Launch the Viewer.”

In my case illustrated below, I was searching for Lidar data for the area around Meteor Crater, Arizona.  After finding it, I was then placed on Open Topography’s site at SDSC for the whole country, requiring me to select my desired area in Arizona again on this new map.  Oddities like this are common to federal data portals, as we document in our book.  Despite this, the US Interagency Elevation Inventory is a useful resource for elevation data.
