hachure
C2Technical, Academic (Cartography, Geology, Art, Drafting)
Definition
Meaning
A short line or stroke used in drawing and engraving, especially on a map, to represent shading or to indicate a slope or relief.
The technique or art of representing terrain relief using such lines; by extension, any similar shading effect.
Linguistics
Semantic Notes
Primarily a term from cartography and topography. It refers both to the individual strokes and the collective pattern they form to indicate relief. In broader artistic contexts, it can refer to any parallel shading lines, but this is less common.

Examples
By Part of Speech
verb
British English
- The steepest parts of the cliff face were carefully hachured on the geological survey.
American English
- Early USGS topographic maps hachured the mountain ranges before contour lines became standard.
adjective
British English
- The hachure technique gives the map a distinctive, hand-drawn appearance.
American English
- He studied the hachure symbols in the old atlas.
Examples
By CEFR Level
- The old map showed the hills using lots of small lines called hachures.
- The density and orientation of the hachures provide a remarkably intuitive sense of the terrain's gradient and aspect.
Learning
Memory Aids
Mnemonic
Think of 'hatch' (as in hatching lines) and 'ure' (as in texture). Hachures give texture to a map to show slopes.
Conceptual Metaphor
LINES ARE GRADIENTS/SLOPES (The direction and density of lines metaphorically represent the steepness of terrain).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с 'гашюр' (gasyur) или общим 'штриховка' (shtrikhovka). 'Гашюры' (gasyury) — прямой, но редкий термин в картографии. Может быть неправильно переведено как 'тень' или 'оттенок' (shade/hue).
Common Mistakes
- Misspelling as 'hatchure' or 'hachuer'.
- Using it as a general synonym for 'hatching' outside of a terrain/map context.
- Incorrect pluralisation ('hachures' is correct).

FAQ
Frequently Asked Questions
In a broad artistic sense, they are similar, both involving parallel lines for shading. However, in technical usage, 'hachure' is specific to cartography and indicates the direction and steepness of a slope, while 'hatching' is a more general artistic technique.
In British English: /haˈʃʊə/ (huh-SHOOR-uh). In American English: /hæˈʃʊr/ (ha-SHOOR). The stress is on the second syllable.
Yes, though it's rare. It means to mark or shade with hachures. Example: 'The cartographer hachured the eastern slopes.'
Contour lines (lines connecting points of equal elevation) and layered hypsometric tints (colour bands) have largely replaced hachures for precise topographic representation, though hachures are still used for stylistic or schematic purposes.
