1130 Numerical Surface Techniques
and Contour Map Plotting
Application Description


This manual contains a general description of a set of
programs adaptable to application areas that require the
quantitative description of surfaces. These programs make
numerical or analytical approximations to a set of coordinate
values which define a surface, and prepare a display of the
geometry of the surface in the form of a plotter contour map.

INTRODUCTION
In practically all of the sciences and fields of engineering there is the
need to express a surface of interest analytically by an equation or
numerically by a system of data points. In many of these disciplines
there is the further need to express the configuration of a surface
graphically in the form of contour lines on a map or chart. In order
to describe the various types of data on this map or chart, it is desirable
to plot symbols, to letter alphabetic data, to post numeric values, to
provide headings, and to draw various types of boundary lines.

This set of programs provides these functions in such a way that they may
be carried out singly or in various combinations, with no necessity for
intermediate card output. The programs included in the set perform
functions in the areas of:

1. Surface Determination
