Maps Using Hachure and Contour Methods - Alaskool
Hachures are strokes (short line segments or curves) drawn in the direction of the steepest slope (the aspect direction). Steeper slopes are represented by thicker, shorter strokes, while gentler slopes are represented by thinner, longer and farther apart strokes. A very gentle slope or a flat area, like the top of a … See more Hachures are an older mode of representing relief. They show orientation of slope, and by their thickness and overall density they provide a general sense of steepness. Being non-numeric, they are less useful to a … See more In representing relief with hachures on a map, six rules are to be followed, according to G.R.P. Lawrence (1979): 1. The hachures are drawn in the direction of the steepest gradient. 2. The hachures are arranged in rows perpendicular to their direction.

This is the most common way of visualizing elevation quantitatively, and is familiar from topographic maps. Most 18th- and early 19th-century national surveys did not record relief across the entire area of coverage, calculating only spot elevations at survey points. … WebWe love how this map combines digital precision with the alluring aesthetic of hand-drawn cartography.
