w_azimuth

Creates a <code>matrix</code> with directions (i.e., azimuth) to central cell, of specified size <code>k</code>. The matrix can be used as weight matrix when calculating the convergence index (see Examples).

Miscellaneous functions for working with 'stars' objects, mainly single-band rasters. Currently includes functions for: (1) focal filtering, (2) detrending of Digital Elevation Models, (3) calculating flow length, (4) calculating the Convergence Index, (5) calculating topographic aspect and topographic slope.
