A Program to Plot an Annotated Track or a Track and Bathymetry or Magnetic Profile on a Mercator Projection
1976
Blodgett, Marilyn L. | Massinglill, James V.
A program has been written for plotting an annotated track or for plotting a track and the superimposed bathymetry or magnetic profile on a Mercator projection. The program reads the data (navigation, bathymetry, or magnetics) from a magnetic tape in BCD form. The program will annotate every point or every nth point. Navigation is annotated with fix numbers, bathymetry will uncorrected fathoms, meters, or corrected meters, and magnetics with the residual magnetic intensity. The profile series is plotted perpendicular to the track, using uncorrected fathoms or meters for bathymetry and residual magnetic intensity for magnetics. The program was written in Fortran IV for use on a CDC 3800 computer; however, the program can be converted to run on other systems with little difficulty.
