U.S. Geological Survey field efforts are part of an interagency agreement with the National Park Service to monitor the recovery of the island from Hurricanes Florence (2018) and Dorian (2019). Three sites of outwash, overwash, and pond formation were targeted for extensive vegetation ground-truthing, sediment samples, bathymetric mapping with a remote-controlled surface vehicle, and uncrewed aerial systems (UAS) flights to collect multispectral imagery. Five semi-permanent ground control points were also installed and surveyed to act as control for additional aerial imagery collects via plane. UAS imagery were processed in Agisoft Metashape (v. 1.8.1) with surveyed temporary ground control points to produce calibrated multispectral (red, blue, green, red edge, near infrared, and panchromatic) orthoimages and digital surface models. Purpose: Multispectral ortho products are to be used for identification of vegetation and other groundcover classifications. The panchromatic band can be used to pan-sharpen the other ortho products.

Online_Linkage: https://doi.org/10.3133/ofr20211039 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The panchromatic ortho and 5-band ortho were produced from the MicaSense Altum-PT. The accuracy of the multispectral 5-band ortho product was determined by comparing the reflective value of two reflectance calibration tarps that are visible in the imagery to their established value. The RGB orthoimage produced by the Ricoh GRII imagery was not checked in this manner. Horizontal accuracy of all orthoimages was assessed using ground control points (GCPs) in the Metashape projects. It should be noted that GCP-based accuracy estimates of the products are for areas of bare ground or low vegetation where GCPs were placed. Additional sources of error such as poor image-to-image point matching due to vegetation or uniform substrate texture or moving objects, may cause localized errors in some portions of the orthoimages to exceed accuracy values. Processing imagery in 4D (see processing steps) aims to keep related products precise within the reported accuracies. Logical_Consistency_Report: Six flights were flown in total for the field activity. Each flight produced images from the Altum-PT and Ricoh GRII. Two flights were flown per site: New Pond 0, New Pond 1, and New Pond 3. At each site an RGB orthoimage from the Ricoh imagery and a 5-band orthoimage and panchromatic orthoimage from the Altum-PT were created. The products may appear blurry or distorted near tall vegetation, areas of poorer image overlap, and near water (waves, ponds, shorelines), where the data return is often sparse, noisy, and erroneous. No color corrections were applied to the Ricoh RGB ortho products or Altum-PT panchromatic raster. The 5-band ortho product was calibrated in Metashape using a Micasense panel but the downwelling sensor was disabled after testing the difference in the final product. Output band values were also divided by 32768 to get the reflectance values for each band instead of digital numbers. Completeness_Report: The 5-band orthoimage products have been cropped on the alongshore edges to exclude low-confidence areas. All orthoimages were created from interpolated digital elevation models in Metashape. GeoTIFFs are cloud-optimized. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal accuracy is affected by the source data and photogrammetry processing and is difficult to quantitatively test, especially as this is the highest resolution dataset currently available in a very dynamic environment with no surveyed stable features. A cursory qualitative analysis of the UAS orthoimages compared against published ortho images with overlapping extent (Ritchie and others, 2022) indicates the products align well as can be discerned between 2.5-10 cm and 1 meter products. The horizontal root mean square error (RMSE) of the GCPs as reported from the Metashape projects for each site are given here. NP0 GCP (n=5) RMSE was xy: 0.013, 0.018 (m), NP1 GCP (n=3) RMSE was xy: 0.028, 0.032, and NP3 GCP (n=5) RMSE was xy: 0.011, 0.004 (m). These values do not represent the absolute horizontal georeferencing accuracy of the product but provide a better sense of the overall processing accuracy. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: There are no vertical positions associated with these data products, rather the encoded reflectance values in the 5-band multispectral ortho product are evaluated here. The two radiometrically calibrated reflectance tarps visible in the ortho image have known values of 0.48 (light) and 0.12 (dark). The average value of each tarp was evaluated by extracting all the values for each band within the area of each tarp in the 5-band products – the lighter tarp values were consistently lower than published and may be partially due to dirt accumulation over time. The average values of the light tarp, from band 1 to 5, at New Pond 0 were 0.461, 0.481, 0.440, 0.427, 0.443, at New Pond 1 were 0.444, 0.459, 0.449, 0.435, 0.440, and at New Pond 3 were 0.450, 0.447, 0.433, 0.419, 0.426, respectively. The average values of the dark tarp, from band 1 to 5, at New Pond 0 were 0.122, 0.133, 0.125, 0.125, at New Pond 1 were 0.128, 0.125, 0.119, 0.118, and 0.121, and at New Pond 3 0.128, 0.125, 0.124, 0.119, 0.124, respectively. Lineage: Process_Step: Process_Description: The ortho products were created in Agisoft Metashape v. 1.8.1 using the following general steps (see Over and others, 2021 for a more detailed methodology explanation): 1. For each site (NP0, NP1, and NP3) a project was created and Ricoh and Altum-PT imagery (located in larger work citation) was imported. 2. Photos were aligned at a low accuracy and then GCPs were automatically detected in the point cloud. Incorrect detections were removed manually. GCP positions (2022034FA_NCB_GCPs.csv located in the larger work citation) were added to the project in the reference systems NAD83(2011)/UTM Zone 18N and NAVD88 (geoid 18). Accuracies for the GCPs were set to 0.05 m and the camera positions for the Altum-PT images were turned off. The photos were then re-aligned with high accuracy (the pixels were not subsampled) using a keypoint limit of 60,000 and unlimited tie points. 3. The alignment process matched pixels between images to create point clouds and put the imagery into a relative spatial context using the GCPs. The resultant point clouds were filtered using one iteration of the 'Reconstruction uncertainty' filter at a level of 12, one iteration of the 'Projection accuracy' filter at a level of 3, and three iterations of the 'Reprojection accuracy' filter to get to a level of 0.3. With each filter, iteration points are selected, deleted, and then the camera model was optimized to refine the focal length, cx, cy, k1, k2, k3, p1, and p2 camera model coefficients. 4. At this point, multiple ‘chunks’ were created so that independent high quality dense clouds with a low-frequency filtering algorithm could be made from the Ricoh images and Altum-PT images. The dense point clouds were then edited by visual inspection and Metashape’s confidence filter to remove points with a low confidence near the edges and near water bodies. 4. Digital elevation model products were built from the dense clouds and then orthomosaics were built from these with refined seamlines. The first Altum-PT ortho product was transformed so that the bands were all divided by the reflectance normalization factor 32768 (half of the available digital number range or 100% reflectance for each band for 16-bit images) and reordered so that bands 1-5 are in wavelength order, Blue, Green, Red, Red edge, and Near-infrared, respectively. The normalization process produces values that are a unitless reflectance value between 0 and 1, where 1 would be 100% reflectance, i.e. lighter. This 5-band product was exported at 10 cm resolution. The second Altum-PT product was just the panchromatic band and was not transformed, the product was exported at 2.5 cm. The Ricoh product is an RGB product with 5 cm resolution. All products are in NAD83(2011)/UTM Zone 18N and region boundaries were rounded to the nearest 5 m interval. West and south bounds were rounded up and east and north bounds were rounded down. 5. All ortho image products were compressed and turned into a cloud-optimized GeoTIFFs (COG) using gdal_translate with the following command: for %i in (.\*.tif) do gdal_translate %i .\cog\%~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/).
