Description:

Abstract:

Digital surface elevation models (DSMs) of the coastline of Barter Island, Alaska derived from aerial photographs collected on July 01 2014, September 07 2014, and July 05 2015. Aerial photographs and coincident elevation data were processed using Structure-from-Motion (SfM) photogrammetric techniques. These files are single-band, 32-bit floating point DSMs (digital surface models) that represent surface elevations of buildings, vegetation, and uncovered ground surfaces in meters with 23 cm ground sample distance (GSD). The No Data value is set to -32767. The file employs Lempel-Ziv-Welch (LZW) compression.

Purpose:

Orthophotomosaics and coincident elevation data were acquired for the purpose of evaluating coastal change along the coast of Barter Island, Alaska.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Accuracies were evaluated using ground surface coordinates collected by USGS using precision GPS surveying techniques in 2014 and 2016. Horizontal accuracy of the DSMs was determined by the accuracy assessment of the orthoimagery used to derive them. Vertical accuracy was determined from comparison of elevations both at fixed, photo-identifiable points and walking survey transects. Values reported are the mean residual between surveyed ground measurements and image/DSM derived values. See Nolan and others (2015), Gibbs and others (2016), and Gibbs and others (2019), for comprehensive discussion of the accuracy, error analysis, and known anomalies.

Logical_Consistency_Report:

Data quality has been assessed relative to ground elevations collected in September of 2014 and 2016.

Completeness_Report:

This 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:

Horizontal accuracy of the DSMs was determined by the accuracy assessment of the orthoimagery used to derive them. The horizontal radial root mean square error (RMSE; ASPRS, 2015) of the orthoimagery data sets are as follows: BTI_Ortho_20140701 = 19 cm, BTI_Ortho_20140907 = 11 cm, BTI_Ortho_20150705 = 8 cm. Horizontal error was found to be less than the resolution of the derived DSMs.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Vertical accuracy of the DSMs was determined by the comparison between surveyed ground measurements collected at both fixed, photo-identifiable points and walking survey points. The vertical root mean square error (RMSE; ASPRS, 2015) of the DSM data sets based on 8 fixed points are as follows: BTI_DSM_20140701 = 11 cm, BTI_Ortho_20140907 = 9 cm, BTI_Ortho_20150705 = 11 cm. The vertical root mean square error (RMSE; ASPRS, 2015) of the DSM data sets based on all 11007 survey points are as follows: BTI_DSM_20140701 = 8 cm, BTI_DSM_20140907 = 12 cm, BTI_DSM_20150705 = 20 cm.

Lineage:

Process_Step:

Process_Description:

Digital surface models were created from elevation point cloud data in LAS format using the natural neighbor algorithm and half-meter point-thinning method in ArcMap. Where the range of point cloud elevations within a 1-m search radius exceeded 1 meter, the maximum value was applied to the output grid cell. Where the range of elevation values were less than 1-meter, a simple average of the points within the 1-m search radius was calculated. Prior to DSM creation the elevation data was shifted and edited to remove spurious elevation values associated with moving water surfaces. Areas where snow and ice were present in the imagery, particularly July 2014, were masked from the final DSMs. See metadata for orthoimagery and LAS data in the accompanying data release and Gibbs and others (2019) for additional information.
