In statnmap/GeoDist: Constrained distance calculation and associated geotools

Description

Calculate distance from one point to a set of points using adjacency matrix

Usage

Pt2Pts.wo.obstacle(
  dref.from,
  dref.to,
  dref.r,
  r.ref,
  longlat,
  small.dist = TRUE,
  keep.path = FALSE
)

Arguments

dref.from	object of class distref.data for a single point
dref.to	object of class distref.data
dref.r	object of class distref.raster corresponding to r.ref
r.ref	reference raster (only used for its coordinates here)
longlat	Logical. if FALSE, Euclidean distance, if TRUE Great Circle distance. Defined from r.ref.
small.dist	if TRUE, distances <= 1 paths are directly calculated.
keep.path	Logical. Whether to keep SpatialLines of paths. This allows real distances when 2 points are in the same raster cell or close.

Value

Vector of distances of length(B)

Examples
