PHOTOGRAMMETRIC MAP CHECKING

CHECKING OF PHOTOGRAMMETRIC MAPPING BY FIELD METHODS CAN BE COSTLY AND TIME CONSUMING. UNLESS SUCH CHECKING IS THOROUGH THERE IS NO ASSURANCE THAT PORTIONS NOT ACTUALLY COVERED BY FIELD CHECKS WILL COMPLY WITH SPECIFICATIONS. RECOGNIZING THESE DISADVANTAGES, THE CALIFORNIA DIVISION OF HIGHWAYS HAS DEVELOPED A SYSTEM OF PHOTOGRAMMETRIC ANALYSIS PRELIMINARY TO FIELD CHECKING. PHOTOGRAMMETRIC ANALYSIS CONSISTS OF REVIEWING THE COMPILATION DATA IN THE FORM OF MAP MANUSCRIPTS, CONTACT PRINTS WITH CONTROL INFORMATION IDENTIFIED THERON, DIAPOSITIVES, AND FIELD SURVEY NOTES, AS SUBMITTED BY THE MAPPING CONTRACTOR. THE RESULTS OF THE ANALYSIS ARE USED AS A BASIS FOR RECOMMENDING FIELD CHECKS. THIS PAPER DISCUSSES THE DEVELOPMENT OF THE CHECKING SYSTEM, AND ITS PERFORMANCE IN ROUTING PRACTICE. PHOTOGRAMMETRIC ANALYSIS IS AN INTEGRAL PART OF OVER-ALL CHECKING PROCEDURES, AND THE RESULTS OF NUMEROUS FIELD CHECKS ARE INCLUDED. ALSO INCLUDED IS A DISCUSSION OF THE DIRECT AND INDIRECT BENEFITS TOWARD IMPROVEMENT OF MAPPING SPECIFICATIONS. /AUTHOR/
