the “V” points uphill to a higher elevation. Generally, you can connect the apexes of the upward-pointing, “V” shaped contour lines to delineate a stream. Further to this, you can estimate astream gradientby counting the number of contours that cross a stream with the contour interval....
Pantographic apparatus is employed for reproducing the contour lines of a map in such a way that, on the reproduction, they are relatively displaced a definite amount. in order to produce a perspective view. As shown in Fig. 1, the contours I. II, III on a map 4 are reproduced on ...
contour or contour line, line on a topographic map connecting points of equal elevation above or below mean sea level. It is thus a kind of isopleth, or line of equal quantity. Contour lines are drawn on maps with a uniform interval of vertical distance separating them (usually 10, 20, ...
