Evaluation of Automated Coordinatograph and Attendant Photogrammetric Procedures for Highway Design Mapping

摘要

Several large scale mapping projects are used to test the accuracy and efficiency of an automated coordinatograph (automatic plotting table) interfaced to a precision stereoplotter. Test results for evaluating the accuracy capability of the interfaced coordinatograph are established using aerial photography flown at flight altitudes that required photo scale to final map scale enlargement factors of 8.33X and 10X. Withheld horizontal and vertical analytical aerotriangulation test point results are tabulated and used in evaluation of the equipment under study. Test results are compared to large scale mapping accuracies required for compliance with national map standards for highway mapping.
