Note: the ALP example uses detailed information about entities and attributes from the standard, as well as concepts about crosswalks. If you are not yet familiar with these subjects we recommend you look at the section on "Description of the Standard" in course Section 2, the Directory of Entities and Attributes, and the section on crosswalks in course Section 5.

The USDA Forest Service manages 191 million acres of land throughout the United States. The national Automated Lands Project (ALP) is attempting to incorporate the use of modern information management principles and technologies to keep track of all National Forest System realty information. This includes land status data such as land survey net, ownership, use restrictions, and boundaries, operating within an Oracle database linked to ARC/INFO and ArcView in an IBM RISC6000 environment. It is the intent of all ALP development to be fully compliant with NDSI and FGDC standards.

The Forest Service maintains an entity relationship diagram and CASE dictionary, stored at the Information Management Repository (IMR) in Region 8 in Atlanta, Georgia. The ALP entity-relationship diagram includes attributes which crosswalk to entities and attributes in the Cadastral Data Content Standard. There is not a direct correspondence between every ALP entity and every entity in the Standard. For example, the ALP model includes entities for business functions such as mineral rights and withdrawal, and also includes geopolitical boundaries.

A sample ArcView map from the ALP system can be seen in the Nez Perce example.
