Instrument Survey Workshop

19 November 2005


The goal of the Instrument Survey Workshop was to continue collecting field data begun in April 2005 for the making of a site topographic map of the potential Civil War Camp in the Bentley Springs area of Baltimore County, Maryland.

The Workshop was also used to review what a transit does and what Archeologists do with transits. The participants had an opportunity to try each of the necessary tasks associated with using a transit:

  • Instrument set up
  • Turning angles
  • Reading the rod
  • Establishing elevation
  • Calculating distances
  • Setting up control points

A Mapping Workshop, in January 2006, will complete a topographical map of the potential Civil War Site.



CAT members use a transit to measure distances and elevations.
