I have a bounds to a place and created a polygon of that place. How can I generate a random point inside the bounds of that polygon? One way of doing it. This will calculate the bounds of the polygon, then guess a random point inside that bounds, if the point is contained by the polygon, it will put a marker there. // calculate the bounds of the polygon var bounds = new google.maps.LatLngBounds(); for (var i=0; i < polygon.getPath().getLength(); i++) { bounds.extend(polygon.getPath().getAt(i)); } var sw = bounds.getSouthWest(); var ne = bounds.getNorthEast(); // Guess 100 random points inside

I am a little bit confused since everything seems to be alright with the code. The problem is that the polyline won't show up on the map. Here is the function that I call to place polyline everytime I receive a location (I added markers in a similar way and they work great) private void addPolylineLocationOnMap(LatLng newLoc) { PolylineOptions poly = new PolylineOptions() .add(newLoc) .color(Color.BLUE) .width(5) .visible(true) .zIndex(30); googleMap.addPolyline(poly); } A Polyline needs multiple points! For example, pass an ArrayList<LatLng> to your method and use addAll() rather than just

I noticed that when you draw a polyline in google maps you set it's width in pixels (strokewidth). Is there a way I could set that in metres instead? Unfortunately, I don't know any easy way to do this. The API does not appear to have documentation on this and I assume this feature is unsupported. One problem is that the pixels represent a different number of meters at different zoom levels within the API. So it would be a dynamic quantity if the zoom levels are changed. One option might be to compute the width in pixels for representing a given number of meters for a given zoom level. For

I have added polylines but not able to add arrow with direction on google map should be display as below And when it zoom up, more arrow should be display like below I have tried reading various blogs and codes but not able to get the goal I have used following code snippet below: private void DrawArrowHead(MarkerOptions MO, GoogleMap mMap, LatLng from, LatLng to) { // obtain the bearing between the last two points double bearing = GetBearing(from, to); // round it to a multiple of 3 and cast out 120s double adjBearing = Math.round(bearing / 3) * 3; while (adjBearing >= 120) { adjBearing -=

I'm using google maps in my iOS swift project. I want to draw a path between two locations on the map (Not straight line). Any idea how to do that ? Ashish Shah To draw polyline between two locations on Google Map in Swift. // Pass your source and destination coordinates in this method. func fetchRoute(from source: CLLocationCoordinate2D, to destination: CLLocationCoordinate2D) { let session = URLSession.shared let url = URL(string: "http://maps.googleapis.com/maps/api/directions/json?origin=\(source.latitude),\(source.longitude)&destination=\(destination.latitude),\(destination.longitude)

I am using SVG path notation to create markers along with a polyline using Google Maps API v3. Sometimes, after adding a few markers, they just stop showing from the map. If I pan the map, even just 1px, they show again. SVG markers stop showing after adding a few SVG markers show again after pan This happens in FF, Safari, Chrome and iPhone browsers. Here is my code for the polyline: var lineSymbol = { path: g.SymbolPath.FORWARD_OPEN_ARROW, scale:1.5 }; polyOptions = { strokeColor: '#0026b3', strokeOpacity: 1.0, strokeWeight: 1, geodesic: true, icons: [{ icon: lineSymbol, repeat: '100px' }],
