hachure
[symbology] A short line on a map that indicates the direction and steepness of a slope. Hachures that represent steep slopes are short and close together; hachures that represent gentle slopes are longer, lighter, and farther apart.
hachure
Short lines used for shading and denoting surfaces in relief (as in map drawing) in the direction of greatest slope. The thickness and spacing of the lines indicate the amount of relief.
hachure Any series of lines used on a map to indicate the general direction and steepness of slopes. The lines are short, heavy, and close together for steep slopes; longer, lighter, and more widely spaced for gentle slopes.
hachured contour
On a topographic map, concentric contour lines drawn with hachures to indicate a closed depression or basin. Concentric contour lines drawn without hachure marks indicate a hill.

He traced the outlines of the Eason Oil hazy features (in a hachured pattern) on a transparency and then overlaid and registered it to the oil (pinks) and gas (blues) map of Oklahoma. The resulting combination is shown here: ...
A final type of contour that may appear on a topographic map is a line representing a closed depression (such as a sinkhole or a crater at the top of a volcano). These contours will be hachured (they will have small tic marks perpendicular to the ...
Avoid using patterns, especially 'hachures' (a series of parallel lines) as they can copy/print badly and may obscure important underlying detail. (Note: patterns are often necessary and suitable for thematic maps such as geological maps.) ...
