Description: Locations of statewide towns and villages were entered by latitude-longitude, digitized from USGS 1:250,000 quadrangle maps, and heads-up digitizing from USGS 1:250,000 maps based on relative positioning of digital hydrography and digital township lines. Many locations were later updated by snapping them to points in the USGSNAMES coverage obtained from USGS. List of populated places were acquired from Alaska Department of Community and Regional Affairs (DCRA). The classifications of cities is determined by the Department of Community and Regional Affairs.

Description: The Alaska Stand Alone Gas Pipeline (ASAP) Route RTE_ASAP layer depicts the route feature for the Alaska Gasline Development Corporation (AGDC) project area and was developed for the AGDC. GIS data for the project is stored in a geodatabase format and is compiled for distribution in ESRI GIS formats. The AGDC, USGS, and Digital Globe imagery were also used. The data was digitized and prepared in 2009-2011 by the Michael Baker Jr., Inc. Accuracy of this alignment is for preliminary engineering and planning purposes only and is based on mapping on two-foot pixel orthoimagery. Later refinements of this alignment will likely utilize a survey control network developed for the project, thus accuracy will be improved for possible construction planning purposes.
Description: Generalized depiction of physically located permenant roads across the North Slope Ecoregion. Existing roads contain primary and secondary roads identified by DOT, DOG, NSB, and others.
Description: This data set contains lands withdrawn or withdrawn conditionally by the US Fish and Wildlife Service. The Land Status attributes are a snapshot of the Land Information System Database and are only accurate as that database. The data is produced to the aliquot part where possible and to the section (square mile) level where aliquot part is not available in the database record. Where aliquot parts are not available, the data is generalized to the section level. Also USS and Rectangular survey data has not been integrated into the process. At this time, all positions are as calculated or as derived from the township and section protraction. "Aliquot" is a Latin word meaning to divide (a number or a quantity, or in our case, a piece of land) into equal parts leaving no remainder. In legal descriptions, only quarter or half divisions of a section of land are known as aliquot parts. An aliquot part is always described in relation to the four points of the compass, with the use of the standard compass abbreviations, N, W, S, and E .
Description: This data contains the administrative large parcel boundaries for both the state and federal government. It combines the formerly known Legislatively Designated Areas (LDA's), or state parcels, and the Conservation System Units (CSU's), or federal parcels, with data improvements. The CSU's also contained additional federal management units, such as National Forests; hence, the name change. Data improvements are significant compared to previous versions of the LDA's and CSU's. The Public Land Survey System (PLSS) was used for all of the state parcels and several of the federal parcels. The previous LDA's coverage (prior to 2000), was automated at a section level. This dataset delineates the boundaries based on the exact legal description. Special notes about LDA's - The legislature may designate an area for special uses. Areas designated by the legislature may include refuges, sanctuaries, critical habitat areas, ranges, special management areas, forests, parks, recreation areas, preserves, public use areas, recreation rivers, and recreational mining areas. Consult the referenced Alaska Statutes to determine the legal description and special management intent of any particular area. Many areas also have regulations and plans that govern uses within their boundaries. State Wildlife Areas - Includes Sanctuaries, State Range Areas, Critical Habitat Areas and Refuges. They are established under Title 16, Chapter 20 of the Alaska Statutes to protect and preserve the natural habitat and game population or to enhance habitat for particular wildlife species. Most of these areas are managed by the Alaska Department of Fish and Game. State Park Areas - Includes parks, marine parks, recreation areas, state preserves, and special management areas. They are established under Title 41, Chapter 21 of the Alaska Statutes to foster the growth and development of a system of parks and recreational facilities and opportunities in the state, for the general health, welfare, education, and enjoyment of its citizens and for the attraction of visitors to the state. Most of these areas are managed by the Department of Natural Resources, Division of Parks and Outdoor Recreation. State Forest Areas - Includes state forests and resource management areas. They are established under Title 41, Chapter 15 or Chapter 17 of the Alaska Statutes primarily for management of forest resources. These areas are managed by the Department of Natural Resources, Division of Forestry. Other State Multiple Use Areas - Includes public use areas, recreation rivers, and recreational mining areas. They are established under Title 41, Chapter 23 of the Alaska Statutes for special multiple use management of state public land and water resources by the Department of Natural Resources and management of public wildlife resources by the Department of Fish and Game.
