Service Description: This data set depicts land withdrawals within Alaska. Data attributes are a snapshot of the BLM-AK Land Information System Database and are only accurate as that database. Alaska, being a state within the Public Land Survey System (PLSS), describes land to the aliquot part (subsections of larger land plots) where ever possible. Where data is not able to be described with an aliquot part, the data is generalized to the nearest PLSS section (640 acres). Natural boundaries, such as ridge lines and rivers, are examples where aliquot part descriptions can not be used. USS and Rectangular survey data has not been integrated when creating the geospatial depiction from database records. At this time, all positions are as calculated or as derived from township and section protraction.

Subject: This data set was created for general mapping purposes (including wild land fire) to display lands withdrawn within the State of Alaska. The layer uses land descriptions stored in the BLM Alaska Land Information System and merges that with existing geometry to create a geospatial data set. This layer may not be adequate to depict land status at a very fine level and is not intended as a substitute for legal title research. Master Title Plats and casefiles should be used at parcel level and to assist in areas of overlapping land status.
