. Emphasis with the Corps of Engineers and the Port Authority was placed on using GPS for accurate positioning while conducting hydrographic surveys and positioning dredging equipment on the waterways of Boston, MA, and Portsmouth, NH, harbors. Authored several training manuals, power point presentations, and quick reference guides on the correct use of the various GPS receivers.
Instrumental in establishing the MTS Woburn Cooperative Continuously Operating Reference Station, (CORS), site with the capabilities of broadcasting "Real Time Kinematic" (RTK) corrections via the internet and cellular communications.
1999 to 2002. Chief of State's Mapping and Operations with the South Carolina Geodetic Survey
Plan and Coordinate countywide Geodetic Surveys using GPS. Helped initiate the use of the NGS's height modernization methodologies to establish true three-dimensional geodetic control. Introduced real time kinematic surveying to support the state boundary program. Helped establish CORS sites in
Columbia, Florence, and Greenville, SC. Provided coordination for the purchase of equipment, which included the sonar, echogram, GPS receivers, and boat used for hydrographic surveying.
Trimble certified to train with Trimble Navigation's Mapping and GIS programs that include: Asset Surveyor and GPS Pathfinder Office.
Served as Co-Chair of the Foundation Committee of the SC State Mapping and Advisory Commission, SC State Mapping Advisory Committee (SMAC).
1989 to 1999. Planner with the South Carolina Geodetic Survey, Columbia, SC
Fundamental in creating and maintaining a network of Trimble Navigation's Pathfinder Community Base stations in
Columbia, Greenville, and Charleston, SC.
Post-processed, adjusted, blue-booked, and submitted to the NGS for placement into the National Spatial Reference System (NSRS), several GPS projects. Served as interim Information Technology Manager and Co-Chaired the SC SMAC geodetic control sub-committee.
1984 to 1989. NOAA Corps
First billet the NOAA Ship WHITING. Duties included: the Side-Scan Sonar officer, data collected with the side scan sonar was used to provide 100% bottom coverage for confirmation and verification of reported wrecks and obstructions, Horizontal Control Officer, set control used for hydrographic surveys on Cat Island, Bahamas, with the Magnavox 1502 Transit satellite receiver. Horizontal control work also included the use of the Wild T-2 theodolite and the Hewlett Packard. Other responsibilities included: Navigation Officer, Officer of the Deck, and Dive Master.
Second billet - Assigned to NOAA's NGS. Performed the duties of Mark Maintenance, Reconnaissance, Computer and Observer for several of the NGS GPS field units. Last assignment before resigning commission was to serve as Chief of Party for the first Kinematic GPS field unit.
