create_es_network: Create social-ecological networks

In sLandserve/sLandserv: sLandserv Workshop Functions

Create social-ecological networks

Description

'create_es_network' takes as input a spatial data layer (either real data or result of 'ls_create') and derives the underlying supply (ecological-ecological) network

Usage

create_es_network(
  ls_supply,
  ls_demand,
  es_thresh,
  excludable,
  supply_area,
  demand_area,
  e2e = TRUE,
  params = NULL
)

Arguments

ls_supply	Polygons containing ecosystem service supply areas
ls_demand	Polygons containing ecosystem service demand areas
es_thresh	Distance threshold for the social-ecological links
excludable	Whether the ecosystem service is excludable or not. If 'TRUE' then only one demand node (chosen at random) is connected to each supply node. If ‘FALSE’ then any number of demand nodes can be connected to each supply node
supply_area	Name of the column containing the supply area measure
demand_area	Name of the column containing the demand area measure
e2e	Logical. If 'TRUE' edge-to-edge distances between patches are calculated. If 'FALSE' centroid-to-centroid distances are calculated (the latter is much quicker)
params	Vector containing the parameters used to generate the landscape (if simulated landscapes used, default = NULL)

Value

A list containing the network (and its attributes) and the parameters used to create the network
