Publication_Date: 2020 Title: Shoreline change at Alaska coastal communities, Napakiak, Alaska Geospatial_Data_Presentation_Form: report, geodatabase Series_Information: Series_Name: Report of Investigation Issue_Identification: RI 2020-10 Publication_Information: Publication_Place: Fairbanks, Alaska, United States Publisher: Alaska Division of Geological & Geophysical Surveys Other_Citation_Details: 29 p., 47 sheets Online_Linkage: https://doi.org/10.14509/30552 Description: Abstract: The Division of Geological & Geophysical Surveys has analyzed long-term shoreline change at 48 Alaska communities. Shoreline datasets were compiled from previously published U.S. Geological Survey assessments and created from historical and recent aerial images by the Alaska Division of Geological & Geophysical Surveys. Shorelines were analyzed to calculate shoreline change rates every 25 meters along coastlines and tidally influenced riverbanks using the Digital Shoreline Analysis System (DSAS; Himmelstoss and others, 2018). The geodatabase for each community includes shoreline positions, the alongshore baseline used to cast transects, and transects that include shoreline change rates and statistics. All files can be downloaded free of charge from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30552). Purpose: Many of Alaska's coastal communities are vulnerable to erosion, flooding, and permafrost degradation. However, there are few vulnerability assessment tools available to the public that are complete or that utilize transparent, consistent, and quantitative methods at a scale needed for local planning. This work is an effort to provide numerical shoreline change data to Alaskans for local decision-making and erosion vulnerability assessments. Supplemental_Information: >Baseline: The Baseline line file gives the location of the alongshore baseline used to cast transects. >Rates: Shoreline change is measured at regular intervals along the coast at transects that are cast orthogonal to shorelines from a baseline. Each method used to calculate shoreline change rates is based on measured differences between shoreline positions through time. The reported rates are expressed as meters of change along transects per year. When the user-selected rate-change calculations are processed, DSAS merges the individual module calculations, and the output is made available as a table in ArcMap. The rate-change statistics provided with DSAS have the standardized field headings. Some of the shoreline statistic values listed below require greater than 3 shoreline positions to calculate the statistic. If the shoreline statistic is a null value, there were not enough shorelines analyzed to compute that statistic. >Shorelines: Shoreline positions are a representation of a linear shoreline feature at a given point in time. These data were visually interpreted from historical and current orthorectified aerial photographs and delineated using ArcGIS.

The accompanying delivery report provides additional information about the procedures used to determine uncertainty values for shoreline positions and shoreline change statistics. Logical_Consistency_Report: Not applicable. Completeness_Report: Gaps in shoreline data and transect data may occur due to gaps in orthoimagery data, location and extent of coastal river channels or lakes, and infrastructure impeding the shoreline such as docks, revetments, and roadways. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Shoreline positions are a representation of a linear shoreline feature at a given point in time. These data were visually interpreted from historical and current orthorectified aerial imagery and delineated in ArcGIS. Several factors have the potential to introduce positional uncertainty in the measured or interpreted results. These factors include horizontal uncertainty of the source imagery or ground control and the orthorectified image, spatial uncertainty associated with the imagery's spatial resolution, and uncertainty due to shoreline indicator interpretation during the digitization process. The accompanying delivery report provides additional information about the procedures used to determine uncertainty values for shoreline positions.

Baseline segments assigned an ID = 0 are ignored by DSAS, and no transects will be cast along those line segments. Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Integer Attribute: Attribute_Label: TransOrder Attribute_Definition: Assigned by DSAS on the basis of transect order along the baseline or baselines. If the user manually adds transects to the file in an edit session, they will be added to the end of the transect attribute table and given a new value for TransID (ObjectID). However, TransOrder will be updated to reflect the position of the new transect with respect to the other transect along the baseline. As such, this field provides the user with a method to sort transect attribute data sequentially alongshore, from the start of the baseline segment with an ID=1 to the end of the final baseline segment. Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Integer Attribute: Attribute_Label: Azimuth Attribute_Definition: Assigned by DSAS to record the azimuth of the transect measure in degrees clockwise from North.

Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Integer Attribute: Attribute_Label: TCD Attribute_Definition: The TCD (total cumulative distance) is the measure (in meters) along the shore from the start of the baseline segment with an ID =1 and measured sequentially alongshore to the end of the final baseline segment. Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Double Attribute: Attribute_Label: SCE Attribute_Definition: Shoreline change envelope; the "SCE" value represents the greatest distance among all the shorelines that intersect a given transect.

Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Double Attribute: Attribute_Label: EPR Attribute_Definition: The end point rate (EPR) is calculated by determining the distance between the oldest and youngest shoreline on a DSAS transect and dividing by the time elapsed between the two shoreline dates. If the PDB is applied, two versions of this statistic will be reported: EPRwill include the PDB in the calculations; NB_EPR will omit the PDB. Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Double Attribute: Attribute_Label: EPRunc Attribute_Definition: An estimate of end point rate uncertainty. The shoreline uncertainties for the two positions used in the end point calculation are each squared, then added together (summation of squares). The square root of the summation of squares is divided by the number of years between the two shorelines. If the PDB is applied, two versions of this statistic will be reported: EPRunc will include the PDB in the calculations; NB_EPRunc will omit the PDB. Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Double Attribute: Attribute_Label: LRR Attribute_Definition: A linear regression rate-of-change statistic was calculated by fitting a least-squares regression line to all shoreline points for a particular transect. The best-fit regression line is placed so that the sum of the squared residuals (determined by squaring the offset distance of each data point from the regression line and adding the squared residuals together) is minimized. The linear regression rate is the slope of the line. The rate is reported in meters per year, with positive values indicating accretion and negative values indicating erosion. If the PDB is applied, two versions of this statistic will be reported: LRR will include the PDB in the calculations; NB_LRR will not include the PDB. If the PDB is not applied, the LRR statistic will not include the bias. Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Double Attribute: Attribute_Label: LR2 Attribute_Definition: The R-squared statistic, or coefficient of determination, is the percentage of variance in the data that is explained by a regression. It is a dimensionless index that ranges from 1.0 to 0.0 and measures how successfully the best-fit line accounts for variation in the data. The smaller the variability of the residual values around the regression line relative to the overall variability, the better the prediction (and closer the R-squared value is to 1.0). If the PDB is applied, two versions of this statistic will be reported. LR2 will include the PDB; NB_LR2 will not include the PDB. Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Double Attribute: Attribute_Label: LSE Attribute_Definition: The predicted (or estimated) values of y (the distance from baseline in meters) are computed for each shoreline point by using the values of x (the shoreline date) and solving the equation for the best-fit regression line (y=mx+b). The standard error is also called the standard deviation. This metric evaluates the accuracy of the best-fit regression line in predicting the position of a shoreline for a specific date. If the PDB is applied, two versions of this statistic will be reported. LSE will include the PDB; NB_LSE will omit the PDB. Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Double Attribute: Attribute_Label: LCI90 Attribute_Definition: The standard error of the slope with confidence interval describes the uncertainty of the reported rate for the user-selected confidence value captured as part of the attribute name. If the PDB is applied, two versions of this statistic will be reported. LCI90 will include the PDB; NB_LCI90 will omit the PDB. Attribute_Definition_Source: DGGS and Himmelstoss and others, 2018 Attribute_Domain_Values: Unrepresentable_Domain: Double Attribute: Attribute_Label: WLR Attribute_Definition: In a weighted linear regression (WLR), more reliable data are given greater emphasis or weight towards determining a best-fit line. In the computation of rate-of-change statistics for shorelines, greater emphasis is placed on data points for which the position uncertainty is smaller. If the PDB is applied, two versions of this statistic will be reported: WLR will include the PDB in the calculations: NB_WLR will not include the PDB.
