upload_land

Import and convert a shapefile to an object of class "lconnect". 
Some landscape and patch metrics which are the core of landscape connectivity
metrics are calculated. The shapefile must be projected, i.e., in planar 
coordinates and the first field must contain the habitat categories.

Provides functions to upload vectorial data and derive landscape
connectivity metrics in habitat or matrix systems. Additionally, includes an
approach to assess individual patch contribution to the overall landscape
connectivity, enabling the prioritization of habitat patches. The computation
of landscape connectivity and patch importance are very useful in Landscape
Ecology research. The metrics available are: number of components, number of
links, size of the largest component, mean size of components, class coincidence
probability, landscape coincidence probability, characteristic path length,
expected cluster size, area-weighted flux and integral index of connectivity.
