Off-Line Orthoprinter Software.

Abstract

This effort developed experimental software to expand the digital terrain data input options to the Off-Line Orthophoto Printer (OOP). The additional sources addressed were random terrain relief points, digitized contour data and multiple AS-11B-1 stereoplotter profile data sets. Profile sets compiled from earlier coverage can now be used with more current imagery. The major task was to develop algorithms which could generate profiles compatible with the OOP operating software from the various terrain data sets. Profiles were generated using terrain modeling as well as interpolation schemes. Terrain modeling investigations used polynomial and multiquadratic functions. The multiquadratic function appeared to work with evenly spaced input such as AS-11B-1 profile data while the interpolation scheme was the best choice for digitized contour data. The other major task was to transform the image orientation data and the digital terrain data into a common coordinate system compatible with the OOP operating system. The report covers the mathematics, subroutine descriptions, and test results. (Author)
