This dataset, prepared by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC), provides UAS survey data consisting of aerial imagery and GCP positions and elevations collected at Madeira Beach, Florida, monthly from July 2017 to June 2018 in order to observe seasonal and storm-induced changes in beach topography. Purpose: Surveyed GCPs were collected along with aerial imagery at Madeira Beach, Florida, from July 2017 to June 2018, to produce SfM products in order to observe seasonal and storm-induced changes in beach topography. Points labeled “Control Points” were used in SfM processing, and points labeled “Check Points” can be used for validating the SfM products; it is recommended for SfM processing to use a marker accuracy of 5 centimeters (cm), horizontal and vertical, for non-groin GCPs, and 10 cm horizontal and 5 cm vertical for groin GCPs.

Logical_Consistency_Report: All data fall within expected ranges. Completeness_Report: This dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the entire metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The maximum horizontal standard deviation of all repeatedly surveyed, permanent, GCPs is 3 cm. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The maximum vertical standard deviation of all repeatedly surveyed, permanent, GCPs is 5.5 cm. Lineage: Process_Step: Process_Description: A number of permanent features (for example, parking lot stripes or concrete groin blocks) and temporary targets (black and white, 4-square checked pattern), distributed uniformly throughout the UAS flight operations area, were used as GCPs and were surveyed using a Spectra Precision SP80 GNSS receiver connected to a Continuously Operating Reference Station (CORS) in the Florida Permanent Reference Network (FPRN). Real-time kinematic (RTK) corrections were sampled for 60 seconds and the average positions were recorded, with horizontal position data given in the Universal Transverse Mercator (UTM) projected coordinate system, Zone 17 North (17N), referenced to the North American Datum of 1983 (NAD83), and elevation data referenced to the North American Vertical Datum of 1988 (NAVD88), GEOID12B. The GPS antenna height (2 meters) was entered into the receiver and was accounted for in real time.
