Description:

Abstract:

Six elevation point cloud files in LAZ format (compressed LAS binary data) are included in this data release: 3 raw point clouds of unclassified and unedited points and 3 modified point clouds that were spatially shifted and edited to remove outliers and spurious elevation values associated with moving water surfaces. An XYZ coordinate shift was applied to each data set in order to register the data sets to an earth-based datum established from surveyed ground control points. Points are unclassified and ground-reflected color values in the red-green-blue (RGB) schema are included. The horizontal coordinate system is WGS84, UTM Zone 7 North meters; vertical coordinates are relative to the WGS84 ellipsoid. Aerial photographs were collected from a small, fixed-wing aircraft over the coast of Barter Island Alaska on three separate dates: July 01 2014, September 07 2014, and July 05 2015. Precise aircraft position information and structure-from-motion photogrammetric methods were combined to derive high-resolution elevation point clouds.

Purpose:

These points provide the calculated XYZ (horizontal and vertical) coordinates and RGB (red-green-blue) values of the land surface on the north coast of Barter Island Alaska collected on three dates over one calendar year. The data were acquired in order to demonstrate the utility of using structure-from-motion photogrammetric methods for deriving digital elevation data using imagery acquired from a fixed-wing aircraft in remote environments. Companion data sets, including orthophotomosaics and digital surface models are used to evaluate fine-scale morphological and volumetric change to beaches and permafrost bluffs.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: No formal attribute accuracy tests were conducted.

Logical_Consistency_Report:

Coordinates recorded for each point describe discrete positions in space at the time of capture. No formal logical accuracy tests were conducted on individual points, however, digital surface models derived from the points were compared with GPS-measured locations to determine a relative accuracy of the input data. Elevation values from the ocean and inland water surfaces are not valid because of the inability of the Structure-from-motion (SfM) method to resolve elevations on moving surfaces.

Completeness_Report:

Gaps in the point cloud data represent areas where no elevation could be extracted from the imagery during SfM processing (for example and area in shadow) and/or where erroneous points and artifacts were manually removed after SfM processing.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

The raw point cloud data used to produce the edited and geographically shifted point clouds and subsequent digital surface models. See Nolan and others (2015), Gibbs and others (2016), and Gibbs and others (2019) for a more thorough description of the data acquisition methods.

Process_Step:

Process_Description:

The elevation point clouds from Fairbanks Fodar (bti_140701.las, bti_140907.las, bti_150705.las) were edited to remove buildings, structures, and spurious elevation values associated with moving water surfaces. Points over the ocean surface and along the shoreline were edited by hand. Points associated with the many small lakes and water bodies on the island were removed using a combination of the raster based Vector Ruggedness Measure (VRM) tool in ArcMap (ESRI; Environmental Systems Research Institute, https://www.arcgis.com/home/item.html?id=9e4210b3ee7b413bbb1f98fb9c5b22d4) and the Lasground_new tool, part of the LAStools suite (Isenburg, 2015). Buildings and small structures were also removed using the LASground_new tool. Each data set was shifted in the x,y and z directions in order to adjust the data from a relative coordinate system to a fixed, ground-based coordinate system as measured at a fixed ground control monument. bti_140701 coordinates were shifted 17 cm north, 7 cm west and 132 cm up in elevation; bti_140907 coordinates were shifted 19 cm south, 13 cm west, and 36 cm up in elevation; bti_150705 coordinates were shifted 12 cm south, 6 cm west, and 32 cm up in elevation. See Gibbs and others (2016) and Gibbs and others (2019) for a more thorough description of the methodology.

Overview_Description:

Entity_and_Attribute_Overview:

The attribute information associated with LAS binary points in the LAZ file is standard, as described in ASPRS (2013). Attributes include location (northing, easting, and elevation in UTM Zone 7 North meters in the WGS84 coordinate systems), color (red, blue, and green components), intensity, and classification. All points are classified as 0 (unclassified). The LAZ file format, a lossless compression for LAS binary data, is described in Isenburg (2013).
