The value of these shore-normal measurements increases when sites are revisited seasonally and/or interannually due to the dynamic range of coastal landforms. These static measurements of the shoreface have been collected by a number of stakeholders in Alaska since the 1960s, but, have not historically been published or readily accessible. In cooperation with the Alaska Ocean Observing System, the Alaska Division of Geological & Geophysical Surveys (DGGS) has designed a universal repository to house these coastal measurements. This new database has an interactive map interface that enables easy access to existing profile locations to encourage repeat observations. The database has been designed to accommodate data sets collected with differing techniques, including differential leveling, survey-grade GPS or extraction from digital elevation models. Non-DGGS profile measurements, including community-led efforts, and data sets from state, federal and academic partners have also been incorporated into the database. Contributions from other entities are welcomed. The readily-accessible nature of this database is intended to promote partner and local involvement in community-based coastal monitoring. This data set was created as a means to organize and provide public access to spatial data sets within the state of Alaska's coastal zone. Funding to develop this data set was provided, in part, by the Alaska Ocean Observing System. This work was also funded, in part, with qualified outer continental shelf oil and gas revenues through the Coastal Impact Assistance Program, U.S. Fish and Wildlife Service, U.S. Department of the Interior.

These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships and correspond to subdirectories within the data distribution package. The metadata layer provides an FGDC metadata file and may include other documentation files. Attribute information for each data layer is described in this metadata file under the "Entity_and_Attribute_Information" section. Data layer contents: >Alaska Coastal Elevation Profiles: The data are downloadable as location-specific distribution packages. Within each package are delimited tabular files that contain the profile elevation data. Each file represents measurements from a specific point in time, organized by year and month. true ASCII tabular files unknown Alaska Division of Geological & Geophysical Surveys (907)451-5020 (907)451-5050 3354 College Road Fairbanks AK 99709-3707 USA dggspubs@alaska.gov 8 am to 4:30 pm, Monday through Friday, except State holidays Please view our website (http://www.dggs.alaska.gov) for the latest information on available data.

For DGPS data, the horizontal accuracies are presented as the Root Mean Square (RMS) error of the post-processed positions (typically lower than 10cm). For DEM-derived profile elevation data, the horizontal positional accuracy is dependent upon the ground-spacing of the point data. For elevation profiles obtained with various types of differential leveling techniques, the geographic accuracy of the entire profile location (approximately 10 cm to 1 km) is much poorer than the relative horizontal accuracy of the individual elevation points along each profile. Every effort has been made to infer appropriate horizontal accuracies for these varying methodologies based on all available information associated with the original data set. Vertical Positional Accuracy Report Vertical point location accuracy is highly dependent on the method of data collection. For DGPS data, the vertical accuracies are presented as the Root Mean Square (RMS) error of the post-processed positions (typically lower than 10 cm). For DEM-derived profile elevation data, the vertical positional accuracy is dependent upon the reported vertical accuracy of the underlying data source. For elevation profiles obtained with various types of differential leveling techniques, the vertical accuracy of the entire profile location (approximately 10 cm to 1 m) is much poorer than the relative horizontal accuracy of the individual elevation points along each profile. Every effort has been made to infer appropriate vertical accuracies for these varying methodologies based on all available information associated with the original data set Gaps in profile data exist when DGPS points failed to post-process. This is generally due to receiver malfunction or a low number of observed satellites. These gaps are typically apparent as unsampled sections when viewing the profile elevation data.

DGGS field measurements are collected with a survey-grade Differential Global Positioning System (DGPS) and either post-processed against a static base station or positions are calculated with real-time kinematic (RTK) methods in conjunction with a published or known control point. Data derived from digital elevation model (DEM) surfaces have been extracted along established profile locations at intervals of 1 m in ArcGIS. Additional field information for the survey data was manually added to the data set using ArcGIS. All positional information has been transformed into the WGS84 horizontal datum for use in interactive, online mapping applications. All data sets are visually checked for qualitative positional consistency. 2014-01-01T00:00:00 Database development - In cooperation with the Alaska Ocean Observing System, the Alaska Division of Geological & Geophysical Surveys (DGGS) designed a universal repository to house these coastal measurements.
