Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

ANIMATED GIF: This animated image file (GIF) includes a series of thermal maps—ranging from daily to several weeks apart—made from helicopter overflight thermal imagery of Halema‘uma‘u crater, Kīlauea summit.
Halema‘uma‘u eruption sequence Digital Elevation Models
HVO uses regular Kīlauea summit helicopter overflights of Halema‘uma‘u crater to create digital elevation models (DEMs) of the crater.
Lava Lake Depth March 4th
Data from a Kīlauea summit helicopter overflight on March 4th allowed for the calculation of the depth of the lava in Halema‘uma‘u crater.
