Aerial Survey

January 21, 2010 8:41:37 am

Great River’s surveyors have been in the field preparing for the aerial survey of the project.  You may have noticed large white crosses pinned to the ground in the surrounding area.  These crosses serve as targets that are visible from the plane and are used in aligning the aerial photographs collected during the flight.  These targets will only be in place for a short period of time.  Our survey staff will remove them as soon as the aerial survey is complete.
