Reclamation-Wide Site Investigation Data on Tessel
The new version of Reclamation's web-based GIS system, Tessel, is now Reclamation-wide.
Tessel allows us to view and publish dynamic maps rich with geospatial data for efficient and
standardized geographical information to be shared between regions, local and area offices.
This powerful mapping application may be the best tool to assemble Reclamation site
investigation data in an effort to make the data readily discoverable, accessible, and usable to all
Site investigation data is defined as any field data Reclamation has obtained for aid in planning,
decision making and designing such as groundwater wells, aquifer wells, piezometers, test pits,
direct push, standard penetration, and cone penetrometer test locations, cross-hole shear wave
and soil resistivity surveys, and physical borehole logging.
This research seeks to:
Determine best practices for efficient and effective methods of developing non-project specific
databases for comprehensive use within Reclamation's GIS system. This centralized database will
allow for transparent dissemination of investigation information across regional, local and area
offices, as well as the capability to perform detailed query searches and spatial statistical
Need and Benefit
Currently all site investigation data is project specific, and generally also region or office specific,
meaning that everyone is responsible for managing and storing their own data. This
departmentalization creates a confusing workplace whereby the stakeholders are not clear on
the comprehensive picture. Field investigations are often requested without the knowledge of
prior investigations. Often stakeholders are harboring multiple versions of interim data unsure if
its quality and/or validity. Because of this lack of centralization, design assumptions are often
made without reviewing all available and/or pertinent data.
The ability to have all site investigation information in one place will alleviate the issues
discussed above. In addition, the comprehensive database will provide a great decision making
tool where multiple aspects of the site investigation can be considered. The comprehensive
database will also become a great research tool in potentially relaying historical data for forensic
studies, as well as illuminating problem areas.
