Get the shortest path tree for a given start point
gh_get_spt(start_point, time_limit = 600, distance_limit = -1, columns = gh_spt_columns(), reverse_flow = FALSE, profile = "car")
start_point | The start point as (lat, lon) pair. |
---|---|
time_limit | The travel time limit in seconds.
Ignored if |
distance_limit | The distance limit in meters. |
columns | The columns to be returned. See gh_spt_columns and gh_available_spt_columns for available columns. |
reverse_flow | Use |
profile | The profile for which the spt should be calculated. |
