circle_window

Creates circular focal window around central pixel.

Calculates multi-scale geomorphometric terrain attributes from regularly gridded digital terrain models using a variable focal windows size (Ilich et al. (2023) <doi:10.1111/tgis.13067>).

circle_window function

<dl><dt>radius</dt>
<dd>radius of circular window</dd>
<dt>unit</dt>
<dd>unit for radius. Either "cell" (number of cells) or "map" for map units (e.g. meters).</dd>
<dt>resolution</dt>
<dd>resolution of intended raster layer (one number or a vector of length 2). Only necessary if unit= "map"</dd>
<dt>return_dismat</dt>
<dd>logical, if TRUE return a matrix of distances from focal cell instead of a matrix to pass to terra::focal.</dd></dl>
