Hi i am using goole map API for my application to get the path drawn for my app. But the issues is when i call the following API
http://maps.googleapis.com/maps/api/directions/json?origin=Chicago&destination=158%20Waterston%20Avenue,%20Wolliston,%20MA,%2002170,%20&waypoints=optimize:true%7C134%20Wimbleton%20Drive,%20Longmeadow,%20MA,%2001106,%20%7C&sensor=false&mode=driving
The path drawn as per the value in "points" tag (here we get instruction to path to follow as well as latitude and langitude) from the above API call is as below
Here my current location i am passing is chicago as my current location.
I am drawing the path with mkpolyline function with the lat lon i get from "points" key .
I dont whats the issue there .
Ya after putting some effort i found that we need to pass the parameter avoid = highway , bydefault if we do not pass anything it takes up avoid = tolls so this was the issue i was facinf , later passing avoid = highway gave me the output i needed.

I would like to take a longitude and latitude of a user and determine if they are within a set boundary of property line on the map similar to the rectangles symbolizing buildings.I have looked into using CLGeocoder which returns an address but I would like to be able to determine if the user is within a park, or a property, a neighborhood or even a building which may have multiple addresses within it. What is the best way to go about doing this thank you.
I've searched for solution for that problem on here-api documentation but I can't really find it out ! I'm starting doubt if this even possible.
Ok so basicly what i need to know for now:
1. Is this even possible on this platform ?
2. Using exactly which 'module' (eg. PLATFORM DATA EXTENSION,BATCH GEOCODER)
There is no straight solution to get all districts in a city since district concept varies from one place to another(country-specific). Still you can try one of the below options:
administrative-areas-buildings category in places api
city-town-village category in places api
retrieveAreas mode in geocoder api (apply bbox or increase the radius of prox parameter and see if it works for your location)
Search Text in geocoder can also be used if you are search for districts which match a regex
You can check if the above 1) and 2) are applicable to your location using https://places.demo.api.here.com/places/v1/categories/places?at=41.8369%2C-87.684&app_id=DemoAppId01082013GAL&app_code=AJKnXv84fjrb0KIHawS0Tg
I 've been trying to test the place parameter when used for searching post using the Facebook Graph API. However it does not seem to affect results !!
For example:
https://graph.facebook.com/search?q=coffee&type=post¢er=44,55&distance=1000
in the previous URL results do not change when I change the values of latitude and longitude (44,55) or the radius (1000)
Am I doing something wrong ?
I think the "distance" and "center" parameters only work when you use the parameter "type=place".
e.g. The two links below return demonstrate this.
https://graph.facebook.com/search?q=coffee&type=place¢er=44.270962,55.096039&distance=1000&access_token=[access_token]
https://graph.facebook.com/search?q=coffee&type=place¢er=53.270962,-6.096039&distance=1000&access_token=[access_token]
Once you have all the places returned, you could then do a further search on each place for their posts that contain coffee...
I need to find if the given zip code is within the required radius. For example, if the user has entered 20910, it should be able to determine if it's within 5 mile radius of 20814. Is there a way to do it? Google API or something? Please help.
I'm using C# as the programming language.
I think it's called the havershine formula...

I am trying to figure out how to use the Google Maps URL format for sharing locations as latitude/longitude in an app that I am developing for iPhone.
Example: http://maps.google.com/maps?q=40.77407,-73.96675
This is a point in Central Park, New York. When using this on an iPhone, "Maps" will open and reverse geocoding will be done, resulting in an address on the nearby 5th Ave.
But for sharing a meeting point in Central Park, this is quite useless!
Is it possible to specify any parameter in the query string that will turn off reverse geocoding, so that the exact lat/long position is shown in the "Maps" app on iPhone?
(Compare with the result one will get when entering this url on a desktop, where the exact location will always be pointed out by a green arrow.)
I found the answer myself: Adding "loc:" immediately after "q=" will turn off the reverse geocoding.
Example: http://maps.google.com/maps?q=loc:40.77407,-73.96675
Instead of a generic 'q', which according to specification is treated like a generic query
This parameter is treated as if it had been typed into the query box by the user on the maps.google.com page. q=* is not supported.
you could try ll or saddr.
ll The latitude and longitude points (in decimal format, comma separated, and in that order) for the map center point.
saddr The latitude and longitude points from which a business search should be performed.
The maps url scheme is specified here: http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/MapLinks.html
