Lands Status Atlas Current method of storing spatial data
Automated Lands ProjectSpatial Structure • Structure based on PLSS (townships & sections) • Corner Identifier (PCCS-ID) • Arc Regions identify lands entities. • Each Arc region contains a unique Control Number that links to the same Control Number in Oracle.
CORNER ID’S Township 28s, Range 34eCopper River Meridian Alaska PCCS-ID’s Each section corner contains a pccs-id in the .NAT table. Each section is labeled with its southwest pccs-id. Each land polygon is given a Control Number based on pccs-id and other parameters.

What are the Interagency Issues? • Are we all collecting the same corner ID? (PCCS-ID, GCDB) • Are there digital versions of US Surveys available? (AutoCAD, scanned…) • Should MTP’s and US Surveys reside in one place? (AGDC) • How will ALP, NILS, and SDMS fit together?
