Nineteen temporary ground control points (GCPs) were distributed throughout each survey area to establish survey control. The GCPs consisted of a combination of small square tarps with black-and-white cross patterns and "X" marks placed on the ground using temporary chalk. The GCP positions were measured using post-processed kinematic (PPK) GPS, using corrections from a GPS base station located approximately 5 kilometers from the study area. The GCP positions are presented in a comma-delimited text file. Purpose: These data were collected to characterize the morphology, substrate composition and roughness of intertidal areas to support modeling of coastal storm and wave impacts with sea-level rise as part of the USGS Puget Sound Coastal Storm Modeling System (PS-CoSMoS). The data are also intended to be used to model and evaluate sediment transport and its effects on coastal habitats, a focus of the USGS Coastal Habitats in Puget Sound Project (CHIPS) and its partners to inform resource management and adaptive planning for our Nation's coasts.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: No formal attribute accuracy tests were conducted. Logical_Consistency_Report: No formal logical accuracy tests were conducted. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: GCP positions were measured using survey-grade dual-frequency GPS receivers operating in post-processed-kinematic (PPK) mode. The GPS receivers were placed on short fixed-height tripods and set to occupy each GCP for a minimum occupation time of one minute. The PPK corrections were referenced to a Continuously Operating Reference Stations (CORS) operated by the Washington State Reference Network (WSRN) located approximately 5 kilometers from the study area ('BELI'). The mean reported horizontal precision of these measurements was 0.019 meters, (standard deviation of 0.004), suggesting a total horizontal accuracy of about 0.020 meters. Uncertainty in the horizontal positions associated with tripod centering, antenna height measurement errors, and errors from the weight of the tripod settling onto the GCP tarp during data collection, and possible subsequent rebound of the center of the tarp after removal is unknown. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: GCP positions were measured using survey-grade dual-frequency GPS receivers operating in post-processed-kinematic (PPK) mode. The GPS receivers were placed on short fixed-height tripods and set to occupy each GCP for a minimum occupation time of one minute. The PPK corrections were referenced to a Continuously Operating Reference Stations (CORS) operated by the Washington State Reference Network (WSRN) located approximately 5 kilometers from the study area ('BELI'). The mean reported horizontal precision of these measurements was 0.026 meters, (standard deviation of 0.005), suggesting a total vertical accuracy of about 0.030 meters. Uncertainty in the vertical positions associated with the weight of the tripod settling onto the GCP tarp during data collection, and possible subsequent vertical rebound of the center of the tarp after removal is unknown.
