Calculate paths from a given point to centroids within a specified distance range
calculate_paths_from_point_dist.RdThis function determines the network paths from a specific point to multiple centroids based on distance thresholds. It can compute the shortest, all shortest, or all simple paths depending on the path type specified.
Usage
calculate_paths_from_point_dist(
network,
point,
minDistPts = 2,
maxDistPts = 1500,
centroids,
path_type = "shortest",
max_path_weight = 10,
crs_transform = 27700,
cache_env = NULL
)Arguments
- network
An sfnetwork object representing the network.
- point
An sf or sfc object containing a single point feature from which paths will be calculated.
- minDistPts
The minimum distance (in meters) to consider for path calculations.
- maxDistPts
The maximum distance (in meters) to consider for path calculations.
- centroids
An sf object containing centroids to which paths are calculated.
- path_type
A character string indicating the type of path calculation: 'shortest', 'all_shortest', or 'all_simple'.
- max_path_weight
Maximum weight allowed for paths in network calculations.
- crs_transform
The coordinate reference system to transform to, default is 27700 (British National Grid).
- cache_env
An optional environment for caching results. If NULL, no caching is performed.
