My code snippet is as follows:
import nearestPointOnLine from "@turf/nearest-point-on-line";
import PathFinder from "geojson-path-finder";
import { point, points, polygon, lineString } from "@turf/helpers";
const pathFinder = new PathFinder.default({/*GeoJSON Input*/}, { tolerance: 0.00009 });
var first = nearestPointOnLine(res, point([35.0543, 32.8090]), {units: "meters"})
var last = nearestPointOnLine(res, point([35.05626374504888,32.808065019239095]), {units: "meters"})
const finder = pathFinder.findPath(first, last)
console.log(JSON.stringify(lineString(finder.path)))
from geojson-path-finder.
Hi there,
you shouldn't have to adjust tolerance depending on start or end points. However, the start and end points you give, rounded to the current tolerance, must be vertices in the routing network. If you're not certain start and end points are in the network, what you usually want is to find the closest point of the network and set that as input - exactly how you do that is considered outside the scope of the library, but you can look at the demo code for inspiration.
