View source: R/upload_land.R

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.

1	upload_land(land_path, bound_path = NULL, habitat, max_dist = NULL)

`land_path`	String indicating the full path of the landscape shapefile.
`bound_path`	String indicating the full path of the boundary shapefile. If NULL (default option) a convex hull will be created and used as boundary.
`habitat`	Vector with habitat categories. The categories can be numeric or character.
`max_dist`	Numeric indicating the maximum distance between patches in the same cluster.

An object of class "lconnect". This object is a list with the following values:

`landscape`	Spatial polygon object of class "sf" (package "sf") with cluster membership of each polygon.
`max_dist`	Numeric indicating the maximum distance between patches of the same cluster.
`clusters`	Numeric vector indicating cluster identity of each polygon.
`distance`	Object of class "dist" (package "stats") with eucledian distances between all pairs of polygons.
`boundary`	Spatial polygon of class "sfc" (package "sf") representing the boundary of the landscape.
`area_l`	Numeric with the total area of the boundary, in square units of landscape units.
