CADASTRAL SURVEYS BY PHOTOGRAMMETRY

THE U. S. FOREST SERVICE HAS MORE THAN 281,000 MILES OF PROPERTY LINES BETWEEN LANDS IN THE NATIONAL FOREST SYSTEM AND LANDS OWNED OR ADMINISTERED BY OTHERS. MORE THAN 1,132, 000 LAND SURVEY CORNERS ARE REQUIRED TO CONTROL THESE PROPERTY LINES. BECAUSE OF THE AGE OF MANY OF OUR LAND SURVEYS, THE COMPLEX OWNERSHIP PATTERNS, AND THE MILES OF PROPERTY LINES INVOLVED, THE FOREST SERVICE HAS SOME COMPLICATED PROPERTY LINE PROBLEMS. NATIONAL FOREST SYSTEM LAND FALLS INTO THE FOLLOWING TWO MAIN CATEGORIES AS FAR AS AUTHORITY TO DO OFFICIAL LAND SURVEYING IS CONCERNED: (1) LAND RESERVED FROM THE PUBLIC DOMAIN, AND (2) ACQUIRED LANDS. NATIONAL FOREST SYSTEM LANDS ARE MANAGED UNDER THE PRINCIPLE OF MULTIPLE-USE SUSTAINED YIELD. PUBLIC DEMAND FOR INCREASINGLY INTENSIVE USE OF NATIONAL FOREST SYSTEM LANDS AND RESOURCES CREATES URGENT NEEDS FOR ACCURATE WELL-MARKED PROPERTY BOUNDARIES. THE FOREST SERVICE IN 1958 SET UP A SPECIAL LAND LINE LOCATION BRANCH TO DO CADASTRAL WORK. THE FOREST SERVICE USES PHOTOGRAMMETRY FOR CADASTRAL SURVEYING. PHOTOGRAMMETRIC METHODS FOR CORNER SEARCH AND SURVEYS ARE DESCRIBED. PHOTOGRAMMETRY IS ALSO USEFUL FOR RIGHTS-OF-WAY ACQUISITION AND TO INVESTIGATE MINERAL CLAIMS. IT IS CONCLUDED THAT OFFICIAL LAND SURVEYING, REGARDLESS OF THE SYSTEM, THE METHODS OR EQUIPMENT USED, MUST BE CONDUCTED UNDER A RESPONSIBLE CHARGE OF CAPABLE PROFESSIONAL LAND SURVEYORS WHO ARE DULY AUTHORIZED UNDER STATE OR FEDERAL LAW TO PERFORM THIS SERVICE.
