%description
Changes of landscape diversity and structure can be detected soon if
relying on landscape class combinations and analysing patterns at multiple
scales. 'LandComp' provides such an opportunity, based on Juhász-Nagy's
functions (Juhász-Nagy P, Podani J 1983 <doi:10.1007/BF00129432>).
Functions can handle multilayered data. Requirements of the input: binary
data contained by a regular square or hexagonal grid, and the grid should
have projected coordinates.
