Layer: EPA Tribal Areas (4 of 4): Alaska Native Allotments (ID: 3)

Name: EPA Tribal Areas (4 of 4): Alaska Native Allotments

Display Field: PARCEL_NO

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: <b>Abstract:</b. This dataset is a spatial representation of the Public Land Survey System (PLSS) in Alaska, generated from land survey records. The data represents a seamless spatial portrayal of native allotment land parcels, their legal descriptions, corner positioning and markings, and survey measurements. This data is intended for mapping purposes only and is not a substitute or replacement for the legal land survey records or other legal documents. Measurement and attribute data are collected from survey records using data entry screens into a relational database. The database design is based upon the FGDC Cadastral Content Data Standard. Corner positions are derived by geodetic calculations using measurement records. Closure and edgematching are applied to produce a seamless dataset. The resultant features do not preserve the original geometry of survey measurements, but the record measurements are reported as attributes. Additional boundary data are derived by spatial capture, protraction and GIS processing. The spatial features are stored and managed within the relational database, with active links to the represented measurement and attribute data.<br/> <b.Purpose:</b> This dataset was created to provide an accurate, seamless portrayal of the PLSS native allotment network, based upon survey records. The dataset is intended for use as a base layer for mapping purposes, and as a framework for the portrayal of native land ownership.
