Survey Earth in a Day 8 is a great opportunity to come together once again as a global surveying community to gather data and increase public awareness of the surveying profession. It also provides a forum for teaching others about the significant contribution Survey Grade GPS is making in their lives and communities each day. Those new to GPS/GNSS and the surveying profession will have an opportunity to observe local surveyors in action and learn more about the importance of the profession.

When was the last time the Earth was measured with great precision- in its entirety- by surveyors and geospatial professionals, simultaneously, during the course of a single day? Survey Earth Day 5 2017, of course. the geospatial professionals of the world will have another opportunity to re-visit this monumental first-of-its-kind event in Survey Earth in a Day 7. Thank you to all who participated last year, and welcome to you and all new registrants for the 2019 event!
