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: These images were collected at Madeira Beach, Florida, from July 2017 to June 2018, with sufficient resolution and endlap/sidelap to produce SfM products in order to observe seasonal and storm-induced changes in beach topography.

Publication_Date: 2020 Title: Time Series of Structure-from-Motion Products – Orthomosaics, Digital Elevation Models, and Point Clouds: Madeira Beach, Florida, July 2017 to June 2018 Series_Information: Series_Name: U.S. Geological Survey Data Release Issue_Identification: doi:10.5066/P9L474WC Online_Linkage: https://doi.org/10.5066/P9L474WC Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The Global Navigation Satellite System (GNSS) receiver used on the UAS has a stated horizontal accuracy of 2.5 meters (m) Circular Error Probable (CEP). However, the uncertainty of the location values stored in the Exchangeable Image File Format (EXIF) header of the images is dominated by error attributable to the geotagging process and uncertainty associated with the precision of the internal camera clock. 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: Horizontal positions recorded in the UAS flight logs and later applied to the EXIF header of the images were derived from a mRobotics GPS (u-Blox Neo-M8N / 3DR SOLO Upgrade), which receives signals from Global Positioning System (GPS) and Global Navigation Satellite System (GLONASS) satellites in WGS84 (G1150) EPSG:7660, but is otherwise uncorrected. Receiver horizontal locations are considered accurate to approximately 2.5 m CEP, but photo locations may be off by as much as 20 m due to uncertainty associated with internal clock precision and the geotagging process. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical positions recorded in the UAS flight logs and later applied to the EXIF header of the images are heights above ground level (AGL) and were derived from a mRobotics GPS (u-Blox Neo-M8N/3DR SOLO Upgrade), which receives signals from GPS and GLONASS satellites, but is otherwise uncorrected. Vertical uncertainty in photo locations was calculated to be in the range of +/-5 m. Lineage: Process_Step: Process_Description: During the surveys, low-altitude (60 m AGL) digital aerial imagery was acquired over an approximately 700-m-long and 100-m-wide stretch of coastline. A 3DR Solo UAS quadcopter equipped with a 16.2 megapixel Ricoh GR II digital camera flew shore-parallel lines at approximately 8 meters per second (m/s), collecting true color imagery at a frequency of 1 Hertz (Hz), resulting in image footprints with 80% endlap/sidelap and 1.6 centimeter (cm) ground sample distance (GSD).

Navigational data recorded by an internal GNSS receiver on-board the UAS were downloaded from the telemetry log of the UAS and approximate camera positions at the time of each image capture were interpolated and assigned to each photo. Photos were then converted from DNG to Joint Photographic Experts Group (JPEG) format using IrfanView (version 4.53) and geospatial positions were added to the EXIF headers using Phil Harvey's ExifTool. Image file names represent capture date and time stamp using the following convention: yyyy_mmdd_hhmmss.jpg where yyyy_mmdd represents the year (yyyy), month (mm) and day (dd) of capture and hhmmss the time of capture as hours (hh), minutes (mm), and seconds(ss). If necessary, some JPEGs were altered to the minimum degree possible, in order to remove personally identifiable information (PII). To extract the information from the image headers using ExifTool, the following command can be used (tested with ExifTool version 11.88): exiftool -csv -f -filename -GPSDateStamp -GPSTimeStamp -GPSLongitude -GPSLatitude -n -Artist -Credit -comment -keywords -Caption -Copyright -CopyrightNotice -Caption-Abstract -ImageDescription directoryname/*.jpg > out.csv The -csv flag writes the information out in a comma-delimited format. The -n option formats the latitude and longitude as signed decimal degrees. Process_Date: 20180701 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Christine J.
