This is related to the field activity 2024-016-FA and a collaboration with the National Park Service at Cape Cod National Seashore to monitor the region that falls within the field of view of two video cameras aimed at the beach (CoastCam CACO-02). In March and April 2024, U.S. Geological Survey and Woods Hole Oceanographic Institution (WHOI) scientists conducted field surveys to collect topographic and bathymetric data. A camera (Ricoh GRII) attached to a helium filled balloon-kite (Helikite) took images of the beach for use in structure from motion. High-precision GPS targets (AeroPoints V2) were used as ground control points. Bathymetry was collected in the nearshore using a single-beam echosounder mounted on a surf capable self-righting electric autonomous surface vehicle. Agisoft Metashape (v. 2.1.0) was used to create a digital surface model and orthomosaic with the collected imagery. Purpose: Ground control points (GCPs) are used in the structure from motion (SfM) workflow to produce the high-resolution elevation and true-color dataset, which can be used to observe conditions and change over time and to validate the CoastCam CACO-02.

Online_Linkage: https://doi.org/10.3133/ofr20211039 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: GCP error in the Metashape project is used to assess overall error in the products. Products are also compared to previous surveys to make sure stable points still align. Additional sources of error such as poor image-to-image point matching due to vegetation or uniform substrate texture or moving objects resulting in poor surface reconstruction may cause localized errors in some portions of the DSM to exceed accuracy estimates. Logical_Consistency_Report: The orthomosaic and digital surface model (DSM) are created from GCPs and imagery (see the larger work citation). The extent of the orthomosaic is greater than the DSM because it includes water and edges that do not photogrammetrically reconstruct. All data fall into expected elevation ranges except for points near buildings, the edges, and near water, where the data return is often sparse, noisy, and erroneous. GeoTIFFs are cloud optimized. Completeness_Report: The DSM provided is not interpolated between data holes. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The GCPs (n=10) have a theoretical accuracy of 1-2 cm. The horizontal RMSE of the GCPs was xy: 0.008, 0.014 (m). The final products were compared to the previous survey (see cross-reference) and the orthos and DSMs align at stable features. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The GCPs (n=10) have a theoretical accuracy of 1-2 cm. The vertical RMSE of the GCPs was z: 0.006 (m). The final products were compared to the previous survey at Head of the Meadow (see cross-reference) and orthos and DSMs align at stable features. Lineage: Process_Step: Process_Description: The ground control points were processed with the following steps: 1. Ten AeroPoint 2s were deployed evenly spaced across the survey area. AeroPoint 2s were left on for ~3 hours to collect GNSS data. 2. Once connected to Wifi, the AeroPoint 2 data were uploaded and run through a post-processing kinematic algorithm of the CORS network to get a global accuracy. The data were exported with xyz variances in the horizontal datum NAD83(2011) to produce latitude, longitude, and ellipsoid heights, and then UTM19N and NAVD88 using Geoid 18 was used to produce orthometric heights. These are exported to a CSV file and named 2024-016-FA_Marconi_GCPs.csv. Process_Date: 202403 Process_Step: Process_Description: DSM and orthomosaic was created in Agisoft Metashape Pro v. 2.1.0 using the following general steps (see Over and others, 2021 for details): 1. Metashape project was created with imagery (located in larger work citation 2024-016-FA_Marconi_imagery.zip). Photos were aligned at a low accuracy and then GCPs were automatically detected in the point cloud. The ten GCPs were located and location information added using the CSV file from the previous step. 2. GCP horizontal and vertical accuracy was set to 0.01/0.02 m. The photos were re-aligned with high accuracy (the pixels are not subsampled for increased processing speed) using a keypoint limit of 40,000 and unlimited tie points. 3. Metashape software refined and optimized, using least squares, the camera positions, GCPs, and lens model using gradual selection and optimization parameters of: Reprojection uncertainty = 20, Projection accuracy = 5, and Reprojection error = 0.3 to minimize the distance between the measured points and the software created points (see Over and others, (2021) for a detailed discussion on these parameters). 4. A dense point cloud was generated using high-quality (images are not subsampled) and a low frequency filtering algorithm. The dense point cloud was then edited by hand to remove erroneous points before generating a DSM with interpolation disabled. 5. The DSM was then exported (2024-016-FA_Marconi_DSM_UTM19N_NAVD88_5cm.tif). 6. A second DSM with interpolation enabled was created and from that surface an orthomosaic using the RGB averaged method was created. The orthomosiac was then exported (2024-011-FA_HOM_RGBavg_UTM19N_5cm.tif). 7. Products were Adobe deflate compressed and cloud optimized using gdal_translate with the following command: for %i in (.\*.tif) do gdal_translate %i .\%~ni_cog.tif -of COG -stats -co BLOCKSIZE=256 -co COMPRESS=DEFLATE -co PREDICTOR=YES -co NUM_THREADS=ALL_CPUS -co BIGTIFF=YES (v. 3.1.4 accessed October 20, 2020 https://gdal.org/), where i is the name of each GeoTIFF.
