To those who must give first place to the quantity of relief rather than the quality, as, for example, the geologist or the engineer, a contoured map is now considered essential.
A slight modification of the latter method can be used to advantage when no contoured map is available, and when the points whose elevation is known are not numerous enough to permit the construction of one.
These methods are, in the order of their development, by hachured and by contoured maps.
It necessitates in the first place a good contoured map upon which to draw the sections, but sacrifices much of the advantage thus gained because only a number of points on each contour line are used, instead of the entire line.
A solid block of plaster is used,--the contouredmap being transferred to it--and the plaster is carved down to produce a series of steps like those made by building up the contours.
Excellent illustration of this is found on the "Piedmont sheet" of the contoured maps issued by the United States Geological Survey.
This can be done without materially affecting the accuracy of the model, considered even as a copy of the contoured map.
