Description:

Abstract:

This dataset contains a 1-meter resolution, seamless topobathymetric digital elevation model (TBDEM) and associated spatial metadata for Teller, Brevig Mission, and Port Clarence, Alaska. The TBDEM contains best available multi-source topographic and bathymetric elevation data collected between the years 1900 to 2023. Processing was done by the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC) and results are provided as a Cloud Optimized GeoTIFF (COG).

Purpose:

This product was created to help advance coastal storm response and recovery in Alaskan coastal communities in the wake of the September 2022 extratropical Typhoon Merbok disaster. It is being used by the USGS to support the development of dynamic flood models for more than 20 communities along the northwest coasts of Alaska. This product is intended for reuse by scientists, managers, and the general public. These data can be opened with most geographic information systems (GIS) software for data visualization and analysis purposes.

Supplemental_Information:

Work was funded by Title VII of Division N in the Consolidated Appropriations Act, 2023 (Public Law 117–328) to support direct recovery and rebuilding decisions in the wake of declared disasters related to hurricanes and typhoons in 2022.

Process_Step:

Process_Description:

Define an area of interest (AOI) and gather published topographic and bathymetric elevation datasets with coverage in the AOI.

Process_Date: 20240716

Process_Step:

Process_Description:

View and prioritize source elevation datasets based on date of acquisition, spatial distribution, accuracy, and point density. In general, more recent dates of acquisition, wider spatial distribution, higher accuracy, and higher point density result in a higher priority level. Source elevation datasets are listed in their order of priority in the Lineage section of this metadata file and in the associated spatial metadata, where the first source dataset is of the highest priority.

Source_Used_Citation_Abbreviation: 1900 NOS lead line
Process_Date: 20240716

Process_Step:

Process_Description:

Prepare each source elevation dataset, as applicable. In Global Mapper software: A) transform the source dataset from its native horizontal and vertical spatial reference systems to the appropriate NAD83 (2011) Universal Transverse Mercator (UTM) zone projection and to NAVD88 GEOID12B, respectively. Convert source elevations to NAVD88 by adding a local conversion constant to the native tidal/ellipsoidal heights of the source dataset. Conversion constants used for this work come from NOAA Tides and Currents (https://tidesandcurrents.noaa.gov/) or the Alaska Tidal Datum Portal (https://dggs.alaska.gov/hazards/coastal/ak-tidal-datum-portal.html) for the most recent available tidal epoch for the tide station nearest to the AOI. The local constants used for this project are listed in the last process step of this metadata file, along with any additional transformations that may have been used bring source datasets into NAVD88 GEOID12B. B) Save the transformed dataset as a LAZ point file. C) Clip LAZ point file to AOI polygon. D) Classify and remove non-ground points from structure-from-motion (SfM)-derived digital surface models (DSMs) using lidar auto-classification. E) Spatially thin LAZ file to one-meter resolution, using the minimum value method. F) Clip the LAZ file to all higher-priority datasets using a buffer of 2x the average point density/resolution of the source dataset being prepared. G) Split the LAZ file into two subsets, one containing 95 percent of the points (active points) and the other containing the remaining 5 percent, or every 20th point (check points). The active points are later gridded in the elevation model along with associated interpolation guides to derive the final topographic surface, while the check points are used to compute the interpolation accuracy of the derived surface.

Process_Date: 20240902

Process_Step:

Process_Description:

Create interpolation guides. Interpolation guides are author-defined 3D points, lines, or polygons used to help derive the final topographic surface. Interpolation guides are used to A) smooth or accentuate breaks in slope along shared boundaries of source datasets, B) prevent topographic creep/shoreline migration from onshore regions into offshore regions, C) fill data gaps in source datasets with plausible heights when local knowledge, qualitative field observations, remotely sensed optical imagery, or other information sources are available, or D) otherwise facilitate the seamless integration of all source datasets. Details of interpolation guides used to create the final elevation surface for this release are listed in the last process step of this metadata file.

Process_Date: 20240902

Process_Step:

Process_Description:

Interpolate a one-meter resolution seamless elevation surface from input source data and interpolation guides using the Create Elevation Grid tool (triangulation method).

Process_Date: 20240906

Process_Step:

Process_Description:

Export grid as a Cloud Optimized GeoTIFF (COG) using Global Mapper, clipping the grid bounds to the project AOI and snapping the output raster cells to the appropriate UTM zone projection, using a bilinear resampling method.

Process_Date: 20240906

Process_Step:

Process_Description:

Quantify interpolation error in MATLAB by calculating the mean bias error (MBE) and root mean square error (RMSE) of the final, seamless TBDEM relative to the check point subsets. MBE and RMSE are reported in the Vertical Positional Accuracy section of this metadata file.

Process_Date: 20240906

Process_Step:

Process_Description:

Create spatial metadata for each source dataset by converting LAZ points to simplified bounding polygons and save in an Esri file geodatabase feature class, along with descriptive attributes about the source dataset. Spatial metadata files are further described in the Entity and Attribute Overview section of this metadata file.

Process_Date: 20240906

Process_Step:

Process_Description:

Perform quality checks on the output elevation raster and spatial metadata files, including review of minimum/maximum elevation values, shoreline positions, gridding artifacts, and descriptive attributes.

Process_Date: 20240909

Process_Step:

Process_Description:

Special considerations: A) Vertical datum conversion constants: 0 m NAVD88 is -0.792 above Mean Lower Low Water (at NOAA CO-OPS tide station: 9469239 TELLER, PORT CLARENCE, via Alaska Tidal Datum Portal). B) Additional vertical transformations: none. C) Horizontal georeferencing: 1900 NOS lead line smooth sheet was georeferenced in ArcGIS Pro (1st order polynomial spline) into NAD 1983 (2011) UTM Zone 3N (EPSG: 6332) using the 2012 USGS ifsar and 2024 NOAA multi source datasets as base layers. D) Interpolation guides: the 1900 NOS lead line data were used to create thalweg and channel boundary guides (author-defined 3D points) in Global Mapper to maintain hydrolaulic conectivity in Tuksuk Channel and the Bluestone River. Culverts were identified using the AK DCRA Community Profile CAD Planimetric Features layer (https://dcra-cdo-dcced.opendata.arcgis.com/maps/7f5ca7eafcbb40dc88c06a8a5072b6e3/about) and NOAA ShoreZone oblique aerial imagery (https://alaskafisheries.noaa.gov/mapping/sz/). Each culvert was digitized into a 3D polygon and used in the interpolation step above.
