This 3D model of Pu‘u ‘Ō‘ō's crater was created from thermal images during an overflight of the cone. The deepest portion of the crater is about 320 meters (1050 feet) below the crater floor that existed prior to April 30.
What is a digital elevation model (DEM)?
A Digital Elevation Model (DEM) is a representation of the bare ground (bare earth) topographic surface of the Earth excluding trees, buildings, and any other surface objects.
DEMs are created from a variety of sources. USGS DEMs used to be derived primarily from topographic maps. Those are being systematically replaced with DEMs derived from high-resolution lidar and IfSAR (Alaska only) data.

What is the difference between lidar data and a digital elevation model (DEM)?
Light detection and ranging (lidar ) data are collected from aircraft using sensors that detect the reflections of a pulsed laser beam. The reflections are recorded as millions of individual points, collectively called a “point cloud,” that represent the 3D positions of objects on the surface including buildings, vegetation, and the ground. Digital elevation models ( DEMs ) are one of many...
What data sources are used to produce the 3D Elevation Program (3DEP) DEMs?
The USGS 3D Elevation Program (3DEP) is in the process of collecting high-quality lidar and IfSAR (for Alaska) coverage for all of the United States and its territories. As this new data becomes available, legacy Digital Elevation Models (DEMs) are being systematically replaced with high-resolution DEMs produced almost entirely from the lidar and ifsar data. Legacy DEMs were produced from...
What is the vertical accuracy of the 3D Elevation Program (3DEP) DEMs?
As of 2022, the absolute vertical accuracy of the 3D Elevation Program (3DEP) 1/3 arc-second seamless DEM product within the conterminous United States is approximately 0.82 meters root mean square error (RMSE), based on a comparison to almost 25,000 NOAA National Geodetic Survey OPUS points . Accuracy has improved from a RMSE of 1.55 meters tested in 2013, due to the addition of lidar projects...

Majuro Atoll — Topobathymetric Model
This video is of is a three-dimensional (3D) view of the Majuro Atoll, Republic of the Marshall Islands topobathymetric model which consists of topography (land elevation) and bathymetry (water depth). This video shows the importance of high-resolution, detailed topobathymetric models because the highest natural elevation for the Majuro Atoll is only three meters.
