Urban Visualization
TerraVision can render
VRML and/or GeoVRML models over the terrain. This screenshot
shows TerraVision flying around a complex VRML model of the Washington
DC mall area. Frame rates of 15-20 Hz were achieved
using an NVIDIA GeForce2 card on a PII 450 MHz PC.
Models by Planet 9 Studios.

System Overview
This screenshot shows a number of TerraVisionTM
II windows. There is the main window in the top-left, the Map view
to the left showing part of the Yosemite Valley, a 3-D Viewer in the
top-right with an overhead view of the Yosemite dataset, and another
3-D Viewer showing the earth with the Yosemite dataset embedded within
it. [947x831 pixels]

Monterey Bathymetry Visualization
This image shows TerraVisionTM
positioned over the Monterey Bay, CA, with a bathymetric
(elevation below sea level) model displayed. This shows
the deep underwater valley systems of the bay. 20 m bathymetric
data are provided by the Monterey Bay Aquarium Research
Institute (MBARI).

Datasets Everywhere!
This screenshot shows TerraVisionTM
with 8 different datasets loaded, all of different resolutions, e.g.
1 minute resolution for the globe, 25 m for the Bay Area, 1 m for
Ft Irwin, and 15 cm for Ft Benning. All of these datasets can be stored
on different servers and accessed over the web by TerraVisionTM.

Multiple Datasets
Here we can see TerraVisionTM with
3 datasets. A low-resolution model of the earth, with a higher-resolution
inset for the San Francisco Bay Area, and an even higher-resolution
inset within that for the Palo Alto area. [580x518 pixels]

VRML Model of the SRI campus
In this screenshot we have 1 m USGS
imagery and elevation for the Menlo Park area. We have produced a
3-D VRML model of the SRI Campus, with texture-maps automatically
extracted from aerial imagery. This model is accurately overlayed
over the terrain model. [654x543 pixels]

VRML Clear Air Turbulence Model
This view shows a close-up of a clear
air turbulence model that was generated in VRML and overlayed on a
model of the Colorado Rockies. Clear air turblence model produced
by Don Middleton of the National Center for Atmospheric Research.

VRML Wind Vector Overlay
This view shows an area of Southern California
with a high resolution insert around the Camp Pendleton area and a
VRML model of wind conditions for that region. The wind vectors were
generated by David Cole of the Naval Oceanographic Office. [579x519

High Resolution Data
This screenshot shows TerraVisionTM
browsing a dataset with 15 cm resolution aerial imagery. At this resolution,
cars are clearly distinguishable as well as windows in the buildings.
