virtual reality visualization laboratory uses active stereo eyeware
to make an object rear-projected on a screen look truly three-dimensional.
The lab can be experienced at Bureau headquarters in Austin, or
at remote locations by special arrangement. The content includes
results of Bureau research and presentations of public interest.
Field Trip: Big Bend area: "Fly" over five contiguous
U.S. and Mexican parks to investigate the relationship between vegetation
and topography. In this arid region, water is the limiting factor
in plant growth. We processed a LANDSAT image to mimic color infrared
(so growing plants show in red) and draped it on a 3-D topographic
base derived from a digital elevation model (DEM) so that the mountains
"pop up" in 3-D. Viewing this VR model, students will
discover the relationships between elevation, rainfall, and vegetation.
Plants are found both on mountains and along the Rio Grande river
Edwards aquifer: This VR model will take you on a trip though
the prolific Edwards aquifer, the source of water for many important
public uses: farming, ranching, drinking water for the people of
San Antonio and many more. You'll see the aquifer's connection to
the beautiful San Marcos, Comal, and Barton Springs, and the habitat
of many living things. Students see the aquifer from both above
and below the ground surface and understand how the aquifer connects
all these users together.
Exploring for Oil: Students will see the results of Bureau
research in oil and gas exploration. They will see underground using
seismic, and watch an oil reservoir be depleted through time. We
always have a great new model of a reservoir that we are currently
working on to see.
The Bureau's state of the art equipment uses a laser to make very
detailed maps of the land surface elevation. Take an online
field trip with the LIDAR team to their most recently visited
exotic locale, and learn how new maps are made.
