EVS-Standard is C Tech's baseline
customizable 3D analysis and visualization system. EVS-Standard includes
all of the capabilities of EVS for ArcView and adds a modular,
customizable environment for geologists and environmental engineers.
Some of its additional features include: finite difference and finite
element modeling grid generation; 3D fence diagrams; multiple analyte
data analysis; and arbitrary slicing & cutting. In addition it
provides pre- and post-processing for MODFLOW, MT3D and CFEST. EVS-Standard
is tightly integrated with ESI’s Groundwater Vistas.
The diagram to the left is a network of
modules in EVS-Standard that was used to produce the figure at the
bottom of this page. EVS-Standard is a truly modular software package in
which the user graphically interconnects modules to produce customized
applications to meet any need. This modular paradigm is the key to the
flexibility and power of EVS. The ability to create custom applications
and a host of other powerful modules separates EVS-Standard from the
more limited EVS for ArcView.
This model and visualization of a benzene
plume beneath a gas station demonstrates the power of EVS even on a site
with very few sample data locations.
The above model shows the
trichloroethylene groundwater plume below the Vickers site. Monitoring
well screens colored by TCE level are combined with the 40 ppb plume.
Transparent surfaces show ground level, the water table and the bottom
of the aquifer. Three-dimensional buildings were added to provide
spatial references.
