File names are ENAL and ENBL. Program provides complete detail for simple or complex alignments including spiralized or simple curves. Input requirements are: Azimuth and distance between PI's or control points; degree or curve and spiral length when applicable. Output will include Engineering stations for all curves and control points; ordinates and coordinates of all PI's and control points, all curve data i.e., length, delta, semi-tangents, etc., and deflections for spirals and curves. In the event of long curves which must be traversed, the program will calculate direction and distance along the radial line between traverse points and the curve, as well as stationing and deflection angles and POC's as determined. This program was designed as a supplement to ENAL to convert random traverse data, which has control points along a predescribed alignment, into distances and azimuths along the alignment course. It will also provide ordinates and coordinates of all points. Calculating the relationship of triangulation control points to the "preliminary" line in new location work is an example of the function of this program.
