I'm using the Microsoft.Maps.Directions.DirectionsManager API to calculate route directions between two points. Suppose no directions are available between two co-ordinates I want to alert to the user. How do I detect that no route was found.
You can use the directionsError event. This event will fire when it can't calculate directions between two locations. You can try this out here: https://www.bingmapsportal.com/ISDK/AjaxV7#DirectionsModule15

So, Imagine I have a car planning to travel some distance.
Is it possible to create a map on my web page, putting planned route (from location to location), my consumption of my car and it would tell me where I could fill it up again. But only via my preset location.
Could I use some of the API in google maps to create this?
Something similar to this would be Tesla route planner: https://www.tesla.com/en_CA/trips?redirect=no
You can start off with Maps JavaScript API's Directions Service which calculates directions between locations that also contains the distance and duration for the route.
Also check out the example here: https://developers.google.com/maps/documentation/javascript/examples/directions-simple
Hope this helps!
Trying to avoid reinventing the wheel here.
Anyone knows of any API that lets one create a route that starts and ends at the user's position, given as parameter the distance required for the route?
For example, you want to take a walk. A walk of a total of 5KM from home and back to home. Any API that will work with Google Maps to offer routes?
Thanks, as always.
You can implement this with the use of Google Maps API Directions Service which receives direction requests and returns computed results.
Furthermore, with this API, you can create a route that starts and ends at the user's position by Using Waypoints in Routes .
As mentioned,
Travel time is the primary factor which is optimized, but other factors such as distance, number of turns and many more may be taken into account when deciding which route is the most efficient.
Please note, however, that the use of Directions service must be in accordance with the policies described for the Google Maps Directions API.
I'm making an application that is uploading data from a gps device (the collection of points of where the vehicle has traveled). I'm having an issue when the vehicle stops or moves very slowly. The gps uploads repeated coordinates, which are unnecessary data.
Is there a way to check whether two (lat,lng) coordinates fall within the same road segment?
Maybe you can check by reverse geocoding and checking the reference-id in response
https://developer.here.com/api-explorer/rest/geocoder/reverse-geocode
Or you can use Route Match Extension to try to get the correct route.

I am now starting new project and I wanted to know if I could use google maps to solve my problem and get list of countries in selected route.
I tried to search on internet about this but couln't find anything what I needed.
Edit: So I created function which loops through routes steps and by given latitude/longitude coordinates in each step I can get in which country is this step taken by using googles geocoder.geocode function. But now I face new problem while I am looping through steps I get this error: OVER_QUERY_LIMIT indicates the webpage has sent too many requests within the allowed time period.
I even tried to set timeout for 500ms before caling geocode function but no use.
If you do a route request, it will always have details about crossing international boundaries.
Just try doing a from/to request on maps.google.com and you will see in the directions, when it crosses a border.
That same information is available to us to take from the direction response.
I want to calculate the driving distance between two locations [the user's specified locations], before user starts the driving. I used many formulas and getDistanceFrom in CLLocation also, but I am not able to get the perfect the driving distance between those locations.
There is much difference in actual and calculated distance.
Please help me to calculate the driving distance between two locations.
How can I use Google Maps API to calculate the driving distance ?
I have already use the regexkitlite to show the road path on Google Maps between the two place. However I can't calculated the path distance.
If you have any code/link, please send it to me.
Thanks in advance....
See directions API of Google Maps
You have just to make a HTTP request:
http://maps.googleapis.com/maps/api/directions/output?parameters
Answer could be json or xml. You will find the distance in the answer
If you have two LatLongs you can calculate the direct distance between them; however, since you want driving directions (not as the crow flies) you'll need access to street-center-lines, so you can calculate the distance for each "leg" of the trip.
Google Maps may provide driving directions along with route distance, you'll need to check the documentation for that specific functionality.
edit
On a second look, it appears this may not be available on the API (as of 2006), but a work-around is posted here: http://groups.google.com/group/Google-Maps-API/msg/4dc2fad4f74e3314
Using Core Location API it will only give you the distance between two point in a straight line - most roads aren't, and hence the distance will be wrong.
