Historic Surveying Webinar

Presented by: Chas Langelan

Description:
Mason & Dixon’s five-year boundary survey, which monuments the lines of Pennsylvania, Maryland and Delaware, remains a remarkable effort in history. Accomplished before the Revolution, using nothing but the stars and three remote legal “bounds” decreed from England, the two surveyor-astronomers brilliantly laid out more than 300-miles of border, settled long colonial disputes and ultimately created the quasi-legal division between free and slave states in pre-Civil War America. It’s a story of pioneering technical achievement--one that all Pennsylvania land surveyors should know and appreciate.

This presentation will cover the ancient disputes and scientific triumphs Mason & Dixon attained in positioning the lines, how their survey was actually conducted, and the exceptional activities planned for Philadelphia this August at Surveyors Rendezvous 2013, which we hope every Pennsylvania surveyor will support and attend.

Special Announcement:
A portion of the profit from this webinar will go to the Surveyors Historic Society.
