This 10-hour continuing education course for land surveyors provides and in-depth exploration of the rectangular system of public land surveys, a foundational method for land identification and legal description that has been in continuous use since 1785. While large-scale original surveys are now less common outside of Alaska, the principles and practices of the rectangular system remain relevant in many aspects of modern surveying.
The course offers a comprehensive discussion of the historical and contemporary field procedures used within this system. Participants will learn about the original survey methodology, which involved extending rectangular grids into unsurveyed lands, as well as modern practices that emphasize the use of protraction diagrams and predetermined survey plans to conduct surveys in isolated areas.
Key topics include creating and modifying protraction diagrams, generating special instructions diagrams when protractions are unavailable, and understanding the nuances of historically and currently applied techniques. This course equips surveyors with the knowledge necessary to apply these practices effectively, ensuring precision in land identification and legal documentation.
