Abstract:
This data set contains lands withdrawn or withdrawn conditionally for military purposes within Alaska. 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 .
Purpose:
This dataset was created for displaying lands withdrawn or lands withdrawn conditionally for military purposes within the State of Alaska and identification for fire, and for general mapping purposes. The Generalized Land Status layers are graphic depictions of land descriptions stored in the BLM Alaska Land Information System and may not be adequate to depict land status at the parcel level or for legal title research. The Master Title Plat layer may be used as a base map to assist in areas of overlapping land status.
Supplemental_Information:
Alaska Lands: Alaska's 365 million acres were purchased by the federal government from Russia in 1867 for about 2 cents an acre. Most of this land was at one time administered by BLM's predecessor agency, the General Land Office. Legislation such as the Alaska Statehood Act (1958), the Alaska Native Claims Settlement Act (1971) and the Alaska National Interest Lands Conservation Act (1980) radically impacted the land ownership patterns of Alaska. These laws authorized land title transfer to approximately 150 million acres into private ownership. National Parks, monuments, preserves, wildlife refuges and forests were established on more than 100 million acres. After all land title conveyances are completed, the approximately 75 million acres of public lands will be administered by the BLM under the principles of multiple use for the long-term benefit of the American people. BLM is the land title record holder for the United States. Casetype Land Status Casetype Description: Where 233170 is the ALIS Casetype; WC is the Land Status; WDL-DEPT OF DEF MISC is the casetype description. The following casetypes, conveyance land status (WN,WC) and casetype descriptions were used to create this dataset. Casetype is repeated for each of the two land status types. 233170 WC WDL-DEPT OF DEF MISC 233170 WN WDL-DEPT OF DEF MISC 233200 WC WDL-DEPT OF ARMY 233200 WN WDL-DEPT OF ARMY 233300 WC WDL-DEPT OF NAVY 233300 WN WDL-DEPT OF NAVY 233400 WC WDL-DEPT OF AIR FORCE 233400 WN WDL-DEPT OF AIR FORCE

Process_Description:
Created a database view based on the case military withdrawals and conditional withdrawal types used to generate the Generalized Land Status. The following casetypes, land status codes (WC, WN), and casetype descriptions were used to create the database view. Database view also includes the case serial number. 233170 WC WDL-DEPT OF DEF MISC 233170 WN WDL-DEPT OF DEF MISC 233200 WC WDL-DEPT OF ARMY 233200 WN WDL-DEPT OF ARMY 233300 WC WDL-DEPT OF NAVY 233300 WN WDL-DEPT OF NAVY 233400 WC WDL-DEPT OF AIR FORCE 233400 WN WDL-DEPT OF AIR FORCE
