Geodetic Surveying Basics
A precise location isn't very useful if it's also inaccurate. Surveyors can use the National Spatial Reference System to obtain measurements that are both precise and accurate. Learn more about how the National Geodetic Survey provides the framework for all positioning activities in the US: https://geodesy.noaa.gov/ #GeoWeek | National Ocean Service

Sky High Bull's-Eye on Instagram: "What is a GCP (Ground Control Point)?◼️◽️ If you rely on drone mapping for construction, land surveys, or agriculture, Ground Control Points (GCPs) are a key part of creating accurate aerial maps. A GCP is a specific point on the ground with known coordinates, and in order to see the location of these coordinates from a drone photo, physical markers are placed on the ground with the coordinates directly in the center of the marker. Using the visible markers and
