名詞

hachure (plural hachures)

1. (cartography, chiefly historical) A line on a map indicating the steepness of a slope.⁷

• 1990, Oxford University Press, The Oxford School Atlas (27th Edition), page 9, recto:

  "The adjoining Fig. 1 shows a mountainous island with the hill slopes indicated by a method of Hill-shading called 'hachures'. These hachures are lines indicating the direction of the slope. Where the slopes are steep the lines are thick and close together, making a dark shade; when the slopes are less steep the lines are finer and wider apart, gradually tapering off and becoming lighter until they stop where the slope ends, so that there is no hill-shading on level country."

使用する際の注意点

• Unlike contour lines, hachures are drawn in the direction of the slope and their thickness and closeness is used to represent the relief with shading. They are no longer used on most modern maps.
