With a unique center passthrough design, this GCP can be used on already established survey points, which enables mapping to be performed after a surveyor has already taken coordinates. Simply place the survey marker through the 3" x 3" center cutout of the GCP to perform precise aerial mapping with pre established coordinates. The GCP can
