阅读更多关于 How to update marker using live location along a polyline?

问题 My question titles seems to be an existing one, but here is my complete scenario. I have an activity for Map based operations, where am drawing a polyline along a road, lets say a route between two locations. Basically the app tracks the users current location (Traveling by car). So till part everything is working, as in, the route is properly shown, device Location API is giving location updates (kindof exact), and also i was able to change the location updates smoothly, So the issue is, the

问题 I was trying to implement google's snaptoroad api. But I am not getting any output. I am using golang for the implementation. My Code is as follows: mapClient, err := maps.NewClient(maps.WithAPIKey(GoogleApiServerKey)) if err != nil{ log.Println(err) } //Input latlng := maps.LatLng{} path := []maps.LatLng{} latlng.Lat = 9.7162348 latlng.Lng = 76.6702793 path = append(path, latlng) latlng.Lat = 9.7162400 latlng.Lng = 76.715195 path = append(path, latlng) latlng.Lat = 9.7162410 latlng.Lng = 76

问题 I am trying to get smooth route for below route path using road API in Roads Inspector but not getting smooth route.Google road api failing to provide smooth route.Some portion of route is not smooth with actual road route e.g at turns, at bridges etc. Please have look for below route path and provide solution to get smooth route/more accurate route along actual road. Points: 42.04144333333333,-88.060575|42.04123666666667,-88.06014333333333|42.04119166666667,-88.06017166666666|42.040835,-88

PolyLine is not on the roads: it goes straight from one point to other

问题 My map contains multiple points to tap the location of the user from where he passes, but the polyline is not shown on the roads, but shows a direct line from one marker to other. I want my polyline to go across the road: as the roads turns, it should also turn. Here's my relevant code dataholder = FirebaseDatabase.getInstance().getReference("UserLocation"); Log.d("onMapReady", "iam here"); dataholder.addValueEventListener(new ValueEventListener() { @Override public void onDataChange

Google Maps Roads API returns duplicate coordinates and placeIds

阅读更多关于 Google Maps Roads API returns duplicate coordinates and placeIds

问题 I'm implementing google maps roads API to pick up the coordinates where I clicked on the roads. But it returns more than expected coordinates and placeids. Suppose I set a direction from place A to place B using directions API then I clicked some points (lets say 10 points) on the roads to draw the route. In response the roads API is returning more than 10 placeIds and coordinates where I need only 10. Here is the code. <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery

How can I extrapolate farther along a road?

阅读更多关于 How can I extrapolate farther along a road?

Given realtime location data of a moving device over a short period of time, how can I get a lat/long pair further along this road, say, 2 miles, or even better, 5 minutes worth of driving? I see that I can use Google's Roads API to snap to a road given a lat/long pair https://developers.google.com/maps/documentation/roads/snap , but that only gets me part way there. This will be in an Android app. Given a route represented as a List<LatLng> , this function calculates the point on the route that results from travelling distance meters from origin on that route (using the Google Maps API
