A Program for Plotting an Annotated Track.

Abstract

A program has been written for plotting an annotated track on a polar stereographic projection. The program reads the date, navigation, bathymetry, and magnetics, from a magnetic tape in BCD form. The data is annotated every nth point. Navigation is annotated with fix numbers, bathymetry with uncorrected fathoms, meters, and corrected meters, and the magnetics with the residual magnetic intensity. This program enables the user to plot oceanographic parameters in relationship to their geographical position. The polar stereographic projection was used because great circles appear as straight lines and because it has very little distortion in the high latitudes. The program was written in FORTRAN 4 for use on the CDC 3800; however the program can be converted to read on other systems with little difficulty.
