Online_Linkage: https://doi.org/10.5066/P9PGJNE9 Description: Abstract: This part of the data release presents a shapefile that includes a spatial index of orthoimagery and elevation data describing the Alaskan coastline from Icy Cape to Cape Prince of Wales. The data products referenced in this index include orthoimagery, digital surface models, and elevation point clouds which were generated from aerial imagery using structure-from-motion methods. Fairbanks Fodar, a contracted mapping service, collected the aerial imagery in 2016 and created all of the data products referenced here. Due to the enormous extent of this dataset, the products are split into separate files with more manageable sizes. Each polygon in this shapefile index provides a geographic outline of a data file’s coverage, corresponding file name, and data type. Additionally, the orthoimagery and digital surface model files include a link to stream the file using any software that supports access to cloud optimized geotiffs (COGs). Purpose: The tile index enables the user to determine which files describe a specific area of interest without needing to download the entire dataset. Fairbanks Fodar was contracted by the USGS to acquire new airborne data to process into orthoimagery, digital surface models, and elevation point clouds.

Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: No formal accuracy tests were conducted. Logical_Consistency_Report: No formal logical accuracy tests were conducted. The boundaries were created as reference that would allow for an efficient means of navigating the data in the associated data release. Therefore, accuracy of the data boundaries was intentionally reduced to better serve the intended purpose. Completeness_Report: Index polygons were generated for each orthomimagery, digital surface model, and point cloud file. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. The index polygons describe the approximate limits of the data in each file. Orthoimagery and digital surface models also include No Data values beyond the polygons depicted here. The polygons were also simplified to reduce the number of vertices and therefore represent an approximate outline of the data, which may exceed the polygon by up to 100 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Not applicable Lineage: Process_Step: Process_Description: Outlines of the data were generated using ArcMap 10.6. Individual files were added to a Mosaic Dataset, then the data outlines were generated using the Build Footprints tool. The footprints were exported to a shapefile and the Simplify Polygon tool was used to reduce the number of vertices and therefore the file size.
