lc_paths: Create least cost paths between each location
In bsmity13/ADePTR: Acoustic Detection Processing and Visualization Tool in R

Description Usage Arguments Details Value Examples

Creates least cost paths as line objects between each location for any number of individuals.

1	lc_paths(det_locs, conductance)

`det_locs`	A `data.frame` of georeferenced acoustic detections. Could be, e.g., the `data.frame` returned by `proc_dets()` or the `data.frame` returned by `coa_locs()`.
`conductance`	A `RasterLayer` object of conductance, either returned by `raster_conduct()` or a similar object created by the user.

Estimating the least cost paths between a large number of locations can be time consuming.

Returns an object of class lcp_list, which is also a list. List elements are of class lcp_ind. See lc_path_ind for details.

#Load sample data
data(acoustic)

#Process detections and stations
proc.det <- proc_dets(det = acoustic$detections, sta = acoustic$stations)

#Calculate  COAs -- Note, using 6 hour COAs to reduce processing time
coas.6h <- coa_locs(proc.det, Delta_t = "6 hours")

#Initialize raster
r.cond <- init_raster(study_area = acoustic$study_area, res = 0.001)

#Create conductance raster
conduct <- raster_conduct(sa_rast = r.cond, impassable = acoustic$land)

#Create least-cost paths
lcps <- lc_paths(det_locs = coas.6h, conductance = conduct)
