Alaska PLSS Section Grid

Protracted section boundaries were electronically generated using aliquot part algorithms developed by DNR staff. These digital protracted sections are based on a framework of non-graphic township coordinate files. The programs make calculations from the radian measurements representing township corner coordinates. At the time when these section coverages were constructed, both DNR and BLM stored their radian measurements to twelve positions of accuracy, which allows resolution of less than one meter. Polygon attributes contain the BLM index number, meridian, township, range, and section number for each section. This coverage is intended to geographically represent BLM's protracted sections for on-shore townships and DNR's protracted sections for off-shore townships, and is not capable of supporting survey quality area calculations.
