mw_create: Create focal ("moving window") weight matrix
In spatialrisk: Spatial Concentration and Radius-Based Risk Calculations
mw_create R Documentation
Create focal ("moving window") weight matrix
Description
Create a focal ("moving window") weight matrix for use in
terra::focal().
Usage
mw_create(r, radius)
Arguments
r
SpatRaster.
radius
radius of the circle (in units of the crs).
Details
The returned mask includes raster-cell centres whose Euclidean
distance from the focal-cell centre is no greater than 'radius' plus the
full raster-cell diagonal. This conservative expansion accounts for the
possible displacement of both a disk centre and a contributing point from
their respective cell centres.
