Acknowledgment of the USGS Coastal and Marine Geology Program as a data source would be appreciated in products developed from these data, and such acknowledgment as is standard for citation and legal practices for data source is expected.
These points provide the calculated XYZ (horizontal and vertical) coordinates and RGB (red-green-blue) values of the land surface during a mid-day low-tide on 18 March, 2016. The product was created to demonstrate the use of structure-from-motion for coastal research and may be used to develop further datasets, such as the digital elevation models, geomorphic feature mapping, and land cover classification.
* Reconstruction uncertainty - 10 (no units) * Projection accuracy - 6 (no units) * Reprojection error - 0.45 (pixels)The marker error for the ground control points was reduced to 0.083 m (0.43 pixels) from 0.094 m (0.58 pixels).
Are there legal restrictions on access or use of the data?
