%description
Spatial structural diversity refers to the spatial, i.e. horizontal
arrangement of landscape elements and can reveal itself as landscape
features, such as patches and linear features. The 'R' package 'StrucDiv'
provides methods to quantify spatial structural diversity in continuous
remote sensing data, or in other data in raster format. Structure is based
on the spatial arrangement of value pairs. The 'R' package 'StrucDiv'
includes methods to combine information from different spatial scales,
which allows to quantify multi-scale spatial structural diversity.
