polyline

I am working with polylines in google map. Basically i am trying to draw a line on several roads using polyline. Now those polylines are blocking(on top) road labels. I have changed the opacity level for better viewing but i really want Google map labels on top. I have studied styling maps, but i havent found any suitable solutions. Is there a way to do it? Thanks in advance. The tiles(which contain the ground, label, streets etc. ) are delivered as single images, not as layers, so there is no way to put anything between particular features that are shown in the tiles. But there may be

In R - I have imported a polyline shapefile that is not straight (represents a winding interstate highway) into the environment. I have read a .csv file that contains points (latitude/longitude in decimal degrees) into the environment. All of those points lie along the polyline. If I take two random points I can calculate the "as the crow flies" distance between them using great circle distance calculation. But what is needed is distance traveled along the polyline. See reference image: https://i.stack.imgur.com/zhorb.png Is anyone aware of an R package that can calculate the distance between

I'm trying to find the android maps api v2 method that will determine the length of the polyline that I am creating while I am moving. I would put it inside onLocationChanged() for continual updates. Anyone know what the method is and what units the the maps api will display the length? Polyline line = map.addPolyline(new PolylineOptions()); public void onLocationChanged(Location location) { line.add(new LatLng(location.getLatitude(), location.getLongitude()) .width(5) .color(Color.RED)); } you can use Location.distanceBetween on your last location to your current location. If you want a total

I have polyline in my map. I want to know the pixel (screen) xy-coordinates, when user clicks the polyline. Click event only returns the LatLng object, so does anyone have a clue how to get the pixel coordinates from latLng? I would appreciate very much if someone could help me! If you have the LatLng object, you can use the google map projection object to transform it into tile coordinates and then into pixel coordinates: For the docs on the projection class: https://developers.google.com/maps/documentation/javascript/reference#Projection Google's example explaining how to transform a LatLng

How can I add point on a polyline between two existing points on a click polyline event? Thank you! If you are just talking about a Polyline with only 2 points, you could use the center of a LatLngBounds containing the Polyline . Google maps api v3 doesn't implement the Polyline.getBounds() function, though. So you can extend the Polyline class to include a getBounds function: google.maps.Polyline.prototype.getBounds = function() { var bounds = new google.maps.LatLngBounds(); this.getPath().forEach(function(e) { bounds.extend(e); }); return bounds; }; Polyline.getBounds() on a line with only 2
