Mesh Generation for Geological Applications: Los Alamos National Laboratory
Geologic applications for computational grids produced with
LaGriT are
utilized for modeling subsurface porous flow and reactive chemical
transport by finite element and finite difference methods. LaGriT is
also used as the first step in quality analysis of geometric data. The
grid may be the first time data is visualized and errors may be seen.
Projects in which LaGriT is utilized include: Yucca Mountain Site
Characterization Project (YMP), Environmental Restoration at Los Alamos
and Savannah River, Oil and Gas Reservoir Modeling, Semiconductor Design
Modeling, and High Speed Hydrodynamics.
Three-Dimensional Geological Model of Manitoba
Gaywood Matile and Greg Keller of Manitoba Geological Survey have a new
Web site up and running to make available some of the 3D work that was
presented in Denver. It is the first in a series of phases. Part of it
works o nly with Internet Explorer. Remember to scroll down for
instructions on the 2D view page. Comments are welcome!
USGS 3D Geologic Mapping In East-Central Illinois
Through a collaborative effort between the Illinois State Geological
Survey (ISGS) and the U.S. Geological Survey (USGS), the surficial,
glacial deposits have been mapped using newly developed 3-D mapping
methods.
3D Model of the United Kingdom
This 3D model of subsurface Britain was constructed from the 1:625,000
scale geological map, drilling, and deep geophysical investigations. It
represents ten layers from the Moho (at a depth of around 30KM) up to
the base of Quaternary deposits (at a depth of a few meters). Despite
its national coverage, the model is consistent with the most detailed
interpretations of the shallow geology.

The Pacific Northwest Center for Geologic Studies
The Pacific Northwest Center for Geologic Mapping Studies at the
Department of Earth and Space Sciences, University of Washington
(formerly the Seattle-Area Geologic Mapping Project), develops geologic
datasets and maps to support hazard asessments and land use applications
for the Puget Lowland.
Turku Region Water Ltd.
is responsible for planning, conducting, and supervising 3-D geological
mapping and groundwater investigations for an Artificial Recharge
Project of the Virttaankangas Aquifer in southwestern Finland.
Systematic modelling of the shallow subsurface in the British Geological Survey
This page describes the methodology and software tool GSI3D used to
systematically model the shallow subsurface (upper hundreds of metres)
at resolutions equivalent to our 1:50,000 and 1:10,000.
GEO SUM3D
A university based working group GEOSUM3D, based in Germany, was formed
to develop integrated scientific 3D modelling concepts and applied best
practice guidelines. GEOSUM3D uses the GSI3D (Geological Surveying and
Investigation in 3D) methodology and software to integrate and visualize
available 1D, 2D and 3D geo-scientific records. The site provides
several examples of 3D mapping, as well as a forum to discuss maps,
models, and procedures.
