A point dataset containing Census population data. This point locations in this dataset are the centroid of the polygon dataset of current community footprints in the SNK REA derived from the Tiger/Line File (see the process steps for details). (The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined...

The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The TIGER/Line Files include both incorporated places (legal entities) and census designated places or CDPs (statistical entities). An incorporated place is established to provide governmental functions for a concentration...

These community points were derived from Census TIGER files that were redigitized to aerial photos for each of the community. After the developed areas were redigitized, the feature to point tool was ran to create points within each community polygon to designate its geographic center. Energy data from the Alaska Energy Authority (AEA) Power Cost Equalization Program Statistical Report that identified communities with electric utilities participating in the PCE Program and use diesel-fired generators to produce more than 75% of its electrical consumption was joined to these points using 2010 FIPS codes.

The community footprints for the CYR REA were produced by digitally tracing the built areas from satellite imagery. This was done to represent the actual community footprints more accurately than would have been possible from the U.S. Census Bureau’s Topologically Integrated Geographic Encoding and Referencing (TIGER) files. TIGER files are geospatial files with information on several political and administrative units. These shapefiles include polygon boundaries of geographic areas and features, linear features including roads and hydrography, and point features. The communities in Alaska were released as a polygon shapefile, with each community’s boundary identified. However, there were two major concerns with...
This point file was derived from the community footprints for the Central Yukon REA. The points were manually edited and moved from their default position to a location that corresponded with the actual community location based on satellite imagery. The footprint feature class was produced by digitally tracing the built areas from satellite imagery.

A polygon dataset of current and future ports in the SNK REA - derived from the Tiger/Line File with modifications (see the process steps for details).
