April 25, 2019, 2:00 - 3:00 pm, Eastern Time
Presenter:
Dr. Michael Dennis, National Geodetic Survey
Webinar Description:
Since 1959, the U.S. has used two types of feet, the “international foot” and the “U.S. survey foot.” They differ by only 0.01 foot per mile, but having both in use creates problems with real costs. This webinar discusses the history of the foot, the importance of standards, and shows how NGS can help move the U.S. to a single foot definition in 2022.
Technical Content Rating:
Technical Content Rating: Beginner: No prior knowledge is necessary.
Watch a short video explaining the difference between the U.S. survey foot and the international survey foot, and the importance of this distinction when working with map projections.
As a reminder, the NGS Webinar Series hosts presentations on various topics related to NGS programs, projects, products and services to educate constituents about NGS activities.
