Contour Map

INTRODUCTION
English translation pending.
CORE DEFINITION
A contour map, also called an isopleth map, represents a continuous field in two dimensions by drawing lines through points that share the same value; elevation contours are the familiar case, and the same technique applies to pressure, temperature, cost, or any scalar. The core proposition is that the spacing between lines encodes the gradient, so closely spaced contours mark steep change and wide spacing marks gentle change. The key qualification is the contour interval, which must suit the field's range, since too coarse an interval hides structure and too fine an interval produces a mass of unreadable lines.
SCAFFOLDING EFFECT
Reduce cognitive load
- Gradient reading: use line spacing to judge where a quantity changes fastest. - Field transfer: apply the technique to any scalar, such as cost, risk, or temperature. - Threshold tracing: follow a single contour to find every point where a value is reached.
Anchor fast decisions
Drawing every value of a field would produce an unreadable mass of numbers, so the map samples the field at regular intervals and connects equal values. The eye reads the resulting lines as topography and infers the third dimension from their shape and spacing. Gradients, which are invisible in a table of numbers, become the most salient feature of the drawing.
