Abstract: 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.
Purpose: This dataset was generated to test the federal Cadastral Data Standards as well as improve the quality of the administrative large parcel boundaries. It can be used for mapping or analysis.
Supplemental Information: Procedures_Used: For a more complete description, please review the final report, The Alaska Land Ownership Mapping Project: Linking State and Federal Program Activities to Build the NSDI. For LDAs - Get copy of legal description from file cabinet in Status Graphics Unit. Make paper copies of all township plats listed in the legal description. Mark boundaries on the paper copies according to the legal description. [Note: Some legal descriptions contain mistakes (typos, punctuation errors, etc.) which can only be officially corrected by the legislature. The obvious mistakes have been corrected for this coverage.] Highlight any discrepancies which will be entered as pending action updates by QC. In ARCEDIT, edit the Albers coverage for this particular LDA to match the marked up paper copies. (Kevin Basnight had created a coverage for each LDA for which there was automated data.) Create a new coverage if one does not exist. See master list of LDAs and corresponding numbers. Use PLSS when adding new arcs that follow aliquot parts. Use /net/shark/d1/lsgis/itm_hydro/ps when adding arcs that follow hydro. Pull surveys and digitize if needed. After all arcs have been included, code all non-aliquot part arcs with ID = 8000. BUILD NODUPS; SAVE If the coverage contains aliquot part arcs that were not input by PLSS, then: Run twpvert.aml to add vertices. Run twpsnap.aml to snap vertices of aliquot part arcs (ID NE 8000) to the quarter-quarter section grid. Go back into ARCEDIT and check that the snapping worked. If not, then snap distance may need to be changed. Run twpsnap.aml again. When polygon coverage is complete, go to /final. Create region coverage and update attributes. Make checkplot checkplt.aml. Submit plot and all paperwork to QC. After all the individual LDA coverages are completed, they can be appended into a single statewide coverage. Run appen.aml This statewide LDA coverage can now be included in a final statewide coverage. For Federal CSUs - see also lineage. Reviews_Applied_to_Data: See above.

Access Constraints: To ensure distribution of the most current public information, please refer requests for data or products to the Alaska Department of Natural Resources, Land Records Information Section.
Usage Constraints: The scale of the data varies from parcel to parcel. You will need to check the scale of the parcel you are interested in mapping for appropriateness. As a whole, it is not recommended the data be used at a scale larger than 1:63,360. Any LDA's can be mapped at large scales, such as 1:4,800. Any hardcopies or published datasets utilizing these data sets shall clearly indicate their source. If the user has modified the data in any way they are obligated to describe the types of modifications they have performed. User specifically agrees not to misrepresent these data sets, nor to imply that changes they made were approved by the Alaska Department of Natural Resources.
