Abstract: High Resolution
Imagery
and 3D Terrain Modeling for Seismic Surveying Planning
Marino, Dewey W. - Space Imaging EOSAT
Field based operations whose goal is
the efficient extraction of ground based information have found utility
in the recent advances in 3D visualization. Progressive seismic planning
and surveying companies are using these new techniques to help efficiently
plan surveys while simultaneously reducing overhead associated with logistical
uncertainties. Virtual helicopter surveys through high- resolution
digital
terrain and imagery give the planner the above ground, site-specific information
necessary to streamline ground operations and minimize access-related expenditures
on exploration targets. Similarly if the survey work is being performed
under contract, the construction of cost models for submitting a bid can
be accurately assessed. Through interpretive techniques, the 3D data set
can be correlated to subsurface structure and modeled to optimize shot
line and bore hole placements.
This technique involves the integration of high
resolution
satellite imagery with engineering quality digital terrain models
and virtual reality software previously developed for military planning
and simulations. This desktop tool allows the user to conduct "real-time"
interactive fly-throughs of "real world" data sets with GIS tools to extract
survey quality geo-referenced information.
Space Imaging EOSAT is making this information commercially. These tools give the virtual surveying capability to all commercial operations planners and put the geo-referenced, global land information on the desktop.
