Are you experienced?

My archaeological experience has been in Field Archaeology mostly as a technician. I have experience as an infrared transit operator and I am familiar with creating data from field sightings to illustrate the archaeological and other landform data through a CAD program, once familiar with, what has become an industry standard, AutoCAD. I have represented remote-sensing data from magnetometers in it and other software and assisted the surveys of land, marsh and one underwater near shore survey. I have used field data for site recording with a close-range photogrammetric system then in development by the Rollei camera company of Germany, working with Canadians of Prometric, Inc. while at Grossman and Associates, Inc. The camera system was used at Mead Hall, Drew University, Madison, NJ, the West Point Foundry site in Cold Spring, NY, an EPA National Priority Superfund cleanup of heavy metals in Foundry Cove marsh, and on another EPA site also using a magnetometer survey, in Saratoga Springs, NY. The idea was that levels of probable contamination would not be overly contacted, and photogrammetrically recorded and so plans and profiles could and were "drawn" back at the "office" after some relatively quick camera setups, Rollei procedure and camera exposures. Photos were developed, 8"x10" prints dot-taped to a large digitizing tablet and software registered, then three dimensional data gathered in software from the photos, and plans and profiles were hand-traced from the multiple photos on the tablet with a magnifying "puck" with buttons once within computed "error ellipses" around control points. I have scanned and integrated traditional field hand-drawn plans and profiles into interim and final reports using graphics software as well as compiling overlays of client supplied GIS CAD maps with historic and archaeological data as required. However, that was over 10 years ago and the desktop computer environment has become better, faster and cheaper. Since, I have been employed in simpler shovel surveys and excavation and look forward to working again in any capacity and I am available.
