%description
Compute spatially explicit land-use metrics for stream survey sites in
GRASS GIS and R as an open-source implementation of IDW-PLUS (Inverse
Distance Weighted Percent Land Use for Streams). The package includes
functions for preprocessing digital elevation and streams data, and one
function to compute all the spatially explicit land use metrics described
in Peterson et al. (2011) <doi:10.1111/j.1365-2427.2010.02507.x> and
previously implemented by Peterson and Pearse (2017)
<doi:10.1111/1752-1688.12558> in ArcGIS-Python as IDW-PLUS.
