AERIAL DRAINAGE SURVEYS
A program is described which attempts to provide, through aerial survey methods, a better and potentially more economical means of obtaining and displaying basic data for highway drainage site analysis. Plots are provided by this program which are as accurate as the aerial photos and stereo plotter will allow. The program will process channel profile and typical section data (x, y, z coordinates) obtained through aerial photography and provide two types of output: output on tape for the computer plotter which makes profile and typical section plots on a special drainage survey form (a plan view, site conditions, and design documentation may later be added to this form for permanent file documentation); printer output of each typical section data is provided in the form of a standard C-16 input coding form which may be used with other hydraulic computer programs. Details are given of the technical procedures, input, and output. A sample problem is described and other program aspects such as definition of symbols, source listing and program revisions are detailed.
