阅读更多关于 Google Maps API [Directions API] Waypoints limitation?

问题 Documentation says that waypoints limit is 8 points. But I have to draw a line with more than 8 waypoints. How to do that? 回答1: Try sending multiple requests. 回答2: The Google Maps Api V3 says: MAX_WAYPOINTS_EXCEEDED indicates that too many DirectionsWaypoints were provided in the DirectionsRequest.

Android: DrivingDirections removed since API 1.0 - how to do it in 1.5/1.6?

阅读更多关于 Android: DrivingDirections removed since API 1.0 - how to do it in 1.5/1.6?

It seems that DrivingDirections have been removed since Android API 1.0 What's the way now to display a map with two points (one of them might be the current location, but can also be any other location) and the direction from one to another in Android 1.6? I suspect the answer is to sign up for a multi-million-dollar license from TeleNav or somebody. The reason the API was pulled was because Google itself has limitations on what it can do with driving directions (e.g., cannot do real-time turn-by-turn stuff), since Google licenses this data from TeleNav or other firms. Google, in turn, cannot

You guys have been helping out solving some of my problems with a Google Map lately, and thank you for that. I am almost done with this - only one problem is left. When I place the first marker on the map, it snaps to the nearest street (which is fine!) but when I drag the first marker to another place, directions suddenly mess up. And the markers get mixes. You can see an example on http://dev.korebogen.dk/gmap/ I need to make it possible to move the first marker (still snapping) and when I place the second marker, the directions first load. But in order to make the first marker snap again, I

For my application I need a server to calculate driving directions. The Google Maps API was designed for clientside use only, with a Javascript and Flash API. Is there any way I can run their API's server-side? As I know it this isn't official and google doesn't support it but it works: $url = str_replace(' ', '%20', "http://maps.google.com/maps/nav?client=yourclient&output=json&q=from: ".$lat1.",".$lon1." to: ".$lat2.",".$lon2); $result = file_get_contents($url); $data = json_decode(utf8_encode($result), true); And you'll have directions in $data array. 来源： https://stackoverflow.com/questions

How to get Google Maps Public Transit Directions by HTTP server-side request

阅读更多关于 How to get Google Maps Public Transit Directions by HTTP server-side request

I use such urls like: http://maps.google.com/?saddr=546%206th%20Avenue,%20New%20York,%20NY%2010011%20(Sixth%20Avenue,%20New%20York)&daddr=W%20103rd%20St,%20New%20York,%20NY%20&dirflg=r But it returns full html page. Does anybody know how to get such info in json or xml or any parsable format? I need public transit. You just add &output=json to the end of the url. I'd like to extend Mathias's answer a little bit. There's no official Google Transit API at the momemnt. Transits are provided by agencies, and most of Transits are not public. So, Google is not allowed to open them as API. You may
