Any of those help For this problem, I looked for Google isLocationOnEdge function, and I found the Java implementation for it PolyUtil. Then the rest is to convert the code to nodejs Javascript code, and it worked fine. code : ## Shortest distance between point and path

it helps some times Are you wanting to calculate this in order to say something like "if the point-to-path distance is zero, then remove the point"? If so, then there is probably an easier way to remove redundant nodes. Take the points three at a time (call them A, B, and C). Calculate the angle between A and B, as well as the angle between B and C. If the two angles are the same, then point B lies in the path between A and C and is redundant. You can use the 'atan2' function (or your language's equivalent) to do the angle calculations. ## d3.js: distance point to svg:path

I hope this helps . In the general case, I don´t think so. An SVG path is a complex element. For instance, if the path is a Bezier curve, the control points may be off the represented line, and the represented shape may be off the bounding box of the control points.
I think that if you have a set of points that you use to generate the path, you may use this points to compute the distance from this points to a given point and get the minimum distance. In the MDN SVG Path Tutorial you can find some examples of complex shapes and how they are made. ## validate route distance beetween two point (lat/lng or address) server side with google maps v3

If you are looking for geographical distance and not driving distance you can use:
code :
``````function distance(\$lat1, \$lng1, \$lat2, \$lng2, \$miles = true) {
\$pi80 = M_PI / 180;
\$lat1 *= \$pi80;
\$lng1 *= \$pi80;
\$lat2 *= \$pi80;
\$lng2 *= \$pi80;

\$r = 6372.797; // mean radius of Earth in km
\$dlat = \$lat2 - \$lat1;
\$dlng = \$lng2 - \$lng1;
\$a = sin(\$dlat / 2) * sin(\$dlat / 2) + cos(\$lat1) * cos(\$lat2) * sin(\$dlng / 2) * sin(\$dlng / 2);
\$c = 2 * atan2(sqrt(\$a), sqrt(1 - \$a));
\$km = \$r * \$c;

return (\$miles ? (\$km * 0.621371192) : \$km);
}
``````

This might help you I'd do the filtering on the fetching of the candidates to display. Either as you publish/subscribe on your template or as you fetch in your helper:
code :
``````Meteor.users.find({
\$near: {
\$geometry: {
type: "Point" ,
coordinates: [ <Employerlongitude> , <Employerlatitude> ]
},
\$maxDistance: <distance in meters>,
\$minDistance: <distance in meters>
}}}).fetch();

fixed the issue. Will look into that further The function I was looking for is named "Distance". This is how to obtain route's distance:
code :
``````            inicial = new PointLatLng(googleGeoCoding(txtorigin.Text).Item2,googleGeoCoding(txtorigin.Text).Item3);

GDirections routedir;
var routefromtable = GMapProviders.GoogleMap.GetDirections(out routedir, inicial, final, chbxhighways.Checked, chbxtolls.Checked, rbtnwalking.Checked, false, false);

GMapRoute tablemaproute = new GMapRoute(routedir.Route, "Ruta ubication");

GMapOverlay tablerouteoverlay = new GMapOverlay("Capa de la ruta");
