Accuracy Defined?
Underwater GPS meets Photogrammetry For a while we have been using GPS located cameras to construct highly accurate models of defensive structures known as pillboxes. Fixing a camera position above the waves is straightforward enough and you can build representative models without additional scale bars or measurements if the GPS signal is accurate. The problems Read more about Accuracy Defined?[…]
