Survey markers in the Linville Gorge area are included as part of the LGMAPS Google Earth Collection. [2], Survey markers in Nagoya, Japan, which bear stylized images of shachihoko, are noted for their elaborate design.[3]. In the U.S., even though surveys carried out primarily by GPS are becoming more common, the network of physical survey markers continues to provide an important check on the accuracy of GPS-based methods, and one that is not dependent on satellites orbiting the earth. GPS Sites provide only GPS satellite signals Non-Operational Sites are not expected to provide data (no data last 30 days) accuracy, and availability are beyond the control of this application.
