The purpose of this SCUREF (South Carolina Universities
Research and Educational Foundation) task (#157) is to develop and implement a
multi-purpose geographic information system (GIS) for storage, retrieval, and
analysis of geologic data at the Savannah River Site (SRS). By the completion
of this project, personnel at SRS will have access to a single system capable
of furnishing a variety of data available for specific areas, sites, and wells
within SRS and adjacent areas. This GIS will decrease time expenditures by
site and contractor personnel for researching existing data and reduce
redundancy of data collection. Data involved include new information obtained
by other ongoing SCUREF projects, as well as the enormous volume of data
already generated and stored in separate facilities and departments at SRS.
Specific objectives of this task include: 1) conversion of
existing surface and subsurface geologic maps, well logs, seismic and other
related hard copy data into a standard GIS format (ARCVIEW, ARC/INFO); 2)
conversion of existing digital geologic data into a standard GIS format; and
(3) conversion and standardization of relevant data generated from other
concurrent SCUREF tasks. This project is being conducted in close coordination
with the Site Characterization Task Team (SCTT) of the Westinghouse Savannah
River Corporation. The SCTT assists in the design of the GIS data base and is
supplying much of the data entered into the data base.
Geological data is collected in a Oracle database. This
database is linked to the Arc/View user interface, allowing the user to
generated SQL based within the GIS which , in turn, refers to data located in
the database. This data may include well parameters, seismic data, data
locations, lithology, etc. In addition to specific geological parameters, the
locations of associated files such as images, spreadsheets, documents and
geophysical log data is also stored in the Oracle database. This allows the
GIS graphical interface to retrieve all the the data associated with a point
or polygon by selection on the GIS generated map or from a tabular view.
