Educate The Public! Together! June 21st @Noon

Survey Earth in a Day is a social surveying education experiment, hosted by Land Surveyors United network.  On the summer solstice June 2015, members of Land Surveyors United(a global support network for land surveyors)  will be simultaneously taking  GPS readings around the globe, in order to correct errors in Google Earth Data.  Our results will change the knowledge we currently have of the shape of the earth and thus provide new information about our planet's surface for the benefit of all man-kind.  Read More
