Survey Earth in a Day


Remeasuring Planet Earth as a Community in a Single Day

On the day of the solstice June 21st, 2018, geospatial professionals around the world and members of Land Surveyors United (a global support network for land surveyors) will be simultaneously recording survey grade GNSS/GPS data from thousands of points around the globe, in order to promote awareness of and a better public understanding of the surveying profession. Measurements made on this day will serve as comparative data from prior events and to expand upon the database of logged points.

Who Participates in SEIAD?

Record Your Point at Noon on Thursday, June 21st

A Global Day of celebration for the Land Surveying Industry. Land Surveyors simultaneously record thousands of points around earth and submit the data to the community. This happens at Noon everywhere on the planet on the longest day of the year- the solstice. On June 20th@Noon, we will Survey Earth in a Day for the 6th time in history. We layer the data from each year on top of previous years to monitor small changes in the surface of the earth, not measurable from satellites or with cell phone accuracy. Only a professional land surveyor can produce such accuracy. #SEIAD7
