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 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 products...
Why don't the elevations on your maps agree with those provided by my GPS system? Which are correct?
Elevations provided by your GPS receiver might disagree with elevations on a USGS map, but they could both be correct if they reference different vertical and/or horizontal datums. The default horizontal datum setting on most GPS receivers is the World Geodetic System of 1984 (WGS84) and the elevations are based on the NAD83 ellipsoid. USGS topographic maps published after 2009 are georeferenced...
Are 3D Elevation Program (3DEP) contour lines updated and what sources were used to create them?
When significant changes in the landscape have occurred, contours will be updated on an as-needed basis. The 100-foot contours were derived from 3DEP (formerly National Elevation Dataset) one arc-second resolution data that was sub-sampled to a cell size of three arc-second. The 50-foot contours were also derived from one arc-second data. Large-scale contours were derived from 1/3 arc-second...

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.

Cartographers in the Field
This Depression-era oil painting was created by USGS field man Hal Shelton in 1940. The painting depicts mapping techniques used in the early days of cartography, including an alidade and stadia rod for determining distances and elevations and a plane-table for sketching contour lines. A USGS benchmark is visible near the top.
