How to measure sinuosity
Web26 sep. 2024 · The sinuosity is defined as a ratio of the distance between start and end point along a line (line length) and the euclidean distance between both points. A large sinuosity signifies a large detour between start and end point and is shown as the red line in the next image: Caculating this measure is straightforward in GRASS GIS with:

The sinuosity index can be explained, then, as the deviations from a path defined by the direction of maximum downslope. For this reason, bedrock streams that flow directly downslope have a sinuosity index of 1, and meandering streams have a sinuosity index that is greater than 1.

Web21 jul. 2004 · Insofar as the measure of the sinuosity of an actual random search path depends on the way the path was discretized at the recording level, and possibly rediscretized afterwards, it is important to decipher the effects due to these processes. Three effects appear to be involved: “scattering”, “smoothing”, and “grazing”. Web11 mrt. 2024 · Ridges can be defined by their length, orientation, and derived metrics (sinuosity, etc.), as well as the number, type, and spatial arrangement of secondary features. Since these features can be georeferenced, they can be used to define slip faces and other features with well-defined upper edges, and indirectly used to define valleys or …
