United States Interagency Elevation Inventory
A common question we receive at OpenTopography is "do you know if there is lidar available for location xxx?". Typically, when we get this question I refer people to the OpenTopography Find Data page (an increasingly rich source for lidar data) and this page of links to online sources of lidar. But, there are large amounts of data collected by federal, state, and local agencies that can be hard to track down.
