Summary

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 [...]

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.
