Section XXVII-1115 - Monocomparator Requirements
Current through Register Vol. 50, No. 9, September 20, 2024
A. If a monocomputer is used for aerial triangulation, all passpoints, checkpoints and drop points (if any) will be marked stereoscopically with WILD PUG or equipment of equal or better precision on every frame on which points appear, and dove prisms shall be used in all four positions for each point marked. The only exception to this requirement will be applicable to points falling in side-laps which are not intended to be used as strip tie points. The maximum diameter of the mark shall be 40 micrometers, with every effort to use a mark of lesser diameter, emulsion permitting.
B. All ground control points, passpoints, checkpoints, drop points (if any) and four corner fiducials will be measured with a comparator having a least count of no greater that 1 micrometer and a root mean square (rms) intrinsic accuracy (calibration applied) of no worse than 2 micrometers. The comparator calibration coefficients shall be included in the aerial triangulation delivery.
AUTHORITY NOTE: Promulgated in accordance with R.S. 50:171.
