阅读更多关于 In Google Maps V3, how can I get a draggable marker to pan the map?

I have found several V2 examples of how to pan the map while a marker is being dragged. For example: http://www.putyourlightson.net/projects/coordinates // create map and add controls var map = new GMap2(document.getElementById("map")); map.addControl(new GLargeMapControl()); map.addControl(new GMapTypeControl()); // set centre point of map var centrePoint = new GLatLng('53.34870686020199', '-6.267356872558594'); map.setCenter(centrePoint, 14); // add a draggable marker var marker = new GMarker(centrePoint, {draggable: true}); map.addOverlay(marker); // add a drag listener to the map GEvent

Best way to display a custom Google maps multiple image marker icon

阅读更多关于 Best way to display a custom Google maps multiple image marker icon

问题 I have two images, one is like an icon and the other is the icon background, what is the best way to combine these two images and make a google marker v3 icon? They are not svg or paths, they are just two png images. 回答1: Simplest way: Use an image editor to make a single image and use that as the icon for your custom marker. If you can't or don't want to do that you can make a custom overlay (reference) that behaves like a marker and use it to overlay the two images in the correct order on

Google Maps API v3 SVG markers disappear

阅读更多关于 Google Maps API v3 SVG markers disappear

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' }],

问题 I have never worked with Google maps API. For the school project I am working on; I need to get a direction between two locations (this is easy part and I think I can do this), However I also need to put an X mark; at every 10 miles along the way.

I am using android maps v2works fine I can add and remove markers onLong Touch on locations. Problem: I would like to drop the marker slowly into the touched location i.e. I want the user to see the marker floating from the top of the screen to the point where it is dropped(touched location).

Change Google map marker orientation according path direction

阅读更多关于 Change Google map marker orientation according path direction

问题 I'd like to know if it possible to change the marker orientation according the path drawn on the map. Here is a example: As you can see the marker is a car (with front bumper and tail lights). I'd like to orientate the car in the direction the path is going (in this exemple orientate the car around 45 degrees to the right). I'm using DirectionsService to draw the path and I have a random number of point. Sometime only one, sometime 10 points. I'm adding the markers before drawing the paths.
