I have a list of points with x, y coordinates. I know how to get the distance between points with sqrt(pow($x2 - $x1, 2) + pow($y2 - $y1, 2)) and the angle between points with atan2(y1 - y2, x1 - x2). How can I calculate the relative angle between the points (left, right, straight)? So, if I'm at point 1, what is the relative direction...
Hello All, I would like to implement google walking/cycle directions into an Android app im creating but I'm struggling to get my head around how to do this. I've recognised that the most accepted way is to query google via http to retrieve a kml file, which is translated back into the android app. owever since I've been java/android pr...
Hi, I read both iPhone and Google Map for iPhone EULA and want to implement a static driving direction map in my iPhone application (native). I am finding a simple way to get route data and display with build-in route display feature in iOS 4 SDK' Mapkit. Is there any programmer implement a feature like this with Google Map and Bing M...
I'm trying to get the distance between two places (by way of roads), and I get that an http request will return a XML with the following data http://code.google.com/apis/maps/documentation/directions/#XML but I don't get how to use NSXMLParser to get the total distance. I would assume to use the parser:didStartElement:namespaceURI:q...
Google gave an example http://googlemapsapi.blogspot.com/2007/05/driving-directions-support-added-to.html Is the source code available somewhere or a tutorial on that precise example ? ...
We are trying to achieve is to collect fake gps tracks on some route without going in real time. We first realized by using maps.google.com we can download kml file from any direction between designated points.But these points depend on shape of the road where if we go through a bridge,kml file comes within only begin and end points of ...
So I'm just learning javascript to mess with the Google Maps API. I was wondering if anyone had an elegant solution to this problem I'm running into. A Google Maps route request must contain three things (origin, destination, and travelMode). My travelMode will always be DRIVING. The origin will always be wherever the user is located. ...
