Calculate distances from one LatLng to many LatLng using Google Places API - google-maps-api-3

I'm developing a small application to search a nearby location from current location.
I type something like "New york" in the textbox then the listview with filled with the list of matched nearby query "New york". I made this done by using Google Place Nearby search API. But I need one thing more is how to get a distance between my current location to every found nearby location. I can do this by calling DistanceMatrix API but it also means that I have to call DistanceMatrixAPI xxx times according to the found nearby location list
Text: "New york"
Distance | Name
0.1km | Place 01
0.5km | Place 02
... | ...
I can absolutely get the distance by using Foursquare API...but anyway I need to work with Google
Any idea?
Thank you alot,

Get Lat/Long from City Auto Complete

I am using a plugin that provides a location field type (City/State/Country, etc) that uses the Google Maps API to autocomplete the field. I am using only the City field. It works as it should: start typing the city and the dropdown fills with possible city/country matches. Then I pick one. Is it possible to extract the lat/long coordinates from the selection made in the dropdown?
If so, how?

Google places api not showing results for some places

Hello i am using simple google map places api to get near by atms for users. My client lives around new york and for some strange reason api shows zero results for that place, but works fine near me (pakistan) . I searched for it a little and found out it was google's issue and some other places were also experiencing the same problem. But i never quite found any solution for this.
This is the get call i use
https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=40.7128,74.1059&radius=10000000&keyword=atm&key=MY_KEY
I would really appreciate the help. Thank you :)
Google place nearby search maximum 50,000 meters (31 miles) . if you try enter more than 50,000 it not work proper.
There is another way for find all ATM in a city. google provide Text Search Requests
https://maps.googleapis.com/maps/api/place/textsearch/json?query=atm+in+Reno,NV,89501,USA&key={API_KEY}
query = keyword + in + city Name
for get city name using latitude longitude
http://maps.googleapis.com/maps/api/geocode/json?latlng=39.52963,-119.81380&sensor=true
For more information how to get city name using latitude longitude
https://developers.google.com/maps/documentation/geocoding/start?csw=1#ReverseGeocoding
for more information about how to use Text Search Requests

OR (second way)
There is another way for find all ATM in a city.
Open Google Maps .
create 10-12 or more points latitude , longitude value to trigger
request.
Then use a loop to find all places within these points.
If you want more appropriate results, increase first trigger points
for your requests.
- It is just a logic i created in php.
$triggerPoints = array("lat1,long1", "lat2,long2", "lat3,long3",....);
foreeach(triggerPoints as $tP){
$requestUrl = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=$tP&radius=[YOUR_RADIUS_VALUE]&type=[YOUR_TYPE]&name=panera&key=[YOUR_KEY_HERE";
$results = file_get_contents($requestUrl);
//Do what you want with response JSON data
}
SHORT ANSWER: Use logical types with your needs.
In my case i used food types instead of supermarket. In some cases, my local market named A101 wasnt found under supermarkets. To find which keywords is best for you, you can search below url with your location and map_key and find most common keywords under types for each query and use it.

Filter Google Places API results based on City

For one of my applications, I will let the users choose a City and then an Area. What I want to achieve is that based on the user's city selection, the Area field(which is using the autocomplete from Google Places) to display areas from that City. Eg: If user chooses the city as New York, the Area field should autocomplete only the areas from New York. Is this something which can be achieved?
1] In autocomplete API, pass the "Lat,Long" in "location" parameter and "100000" in "radius" parameter. It will bias search result within 100Km in that city.
Eg: Pass "40.7128,74.0059" for NewYork and it will give you result within 100Km in NewYork city.
OR
2] There is a trick you can use.If a user chooses a city, just add the city name as a prefix in the search string. It will only give the search suggestions in which the user is searching. eg, pass "NewYork" as a prefix in your search string, now type any word, it will only give you results for NewYork city restaurant, cafes, places, etc
You can do it by restricting the results of your autocomplete by a specified area.
Here are the ways that you can use:
Location Biasing - you may bias the results to a specified circle by passing a location and a radius parameter. This instructs the Place Autocomplete service to prefer showing results within that circle. Results outside of the defined area may still be displayed. You can use the components parameter to filter results to show only those places within a specified country.
Location Restrict - it can restrict the results to the region defined by location and a radius parameter, by adding the strictbounds parameter. This instructs the Place Autocomplete service to return only results within that region.
Places Types - you can restrict results from a Place Autocomplete request to be of a certain type by passing a types parameter. The parameter specifies a type or a type collection, as listed in the supported types below. If nothing is specified, all types are returned.
Hope this information helps you.

How does Google Maps decide when to use a specific icon?

I am using the Google Maps Places library to do a search for nearby hospitals, but it returns results that aren't necessary hospitals (but have 'hospital' as one of their types). However, I've noticed that actual hospitals have a hospital icon on the map, so Google must somehow know which establishments are actually hospitals. Does anyone know if the public has access to this data?
This is the icon I'm referring to: https://www.dropbox.com/s/1jfqcayxavjhlyi/Screenshot%202015-03-17%2017.20.19.png?dl=0
Example of request I'm making:
var request = {
location: self.location,
radius: 20000,
types: ['hospital'],
keyword: 'hospital'
};
Example result that isn't a hospital:
{"geometry":{"location":{"k":44.815958,"D":-68.808244}},
"icon":"http://maps.gstatic.com/mapfiles/place_api/icons/generic_business-71.png","id":"de6e60bd70b90ba4cb86afe149a60169553607f1",
"name":"Penobscot Community Health Center",
"opening_hours":{"open_now":true,"weekday_text":[]},
"photos":[{"height":320,"html_attributions":[],"width":320}],"place_id":"ChIJj--4INRKrkwRN0z2XkoJtVU",
"rating":3.1,
"reference":"CoQBdAAAADmf3YA0659efzMbCSPOK6SZttkfus7aWBDhrZZyX63Szl256BRcpz81LH6rIuONldYv256tsN7Zv-N6ZkOkJadlD2VS01bs7C4ierKvGUMyJOJu657xL5MvidF3Tgs9iejeJcXsxjDJYOwtN3m3sbfClfWYVnnIL4hMLYV8P9TnEhBurfJv_30CAG2wp1V73POVGhR-7fz1mCdh4OYWSa3Pw0mPupckoQ",
"scope":"GOOGLE",
"types":["hospital","pharmacy","store","health","establishment"],
"vicinity":"1012 Union Street, Bangor",
"html_attributions":[]}
My guess is there are a couple ways to get around this. You might remove the keyword argument from the API, which acts like a search term rather than a specific match on a type of location like the type field does.
You may want to be careful about your radius value choice.
Next, if you do a search on Google Maps in general you'll get a broad assortment of results. Do you need every result to be an actual hospital or can you do your own filtering afterwards?
If you do your own filtering it looks like type information and even icons are embedded in the result JSON. You might see if there's a distinguishing characteristic between the types of results you want and filter by that. Otherwise, any additional graphical data would not be accessible via the API.

Google map api v3 markers exclude a city or certain bound

I am using google maps api v3. I have a database of markers with lat and long address that I display on a map and that works fine.
The map is displaying markers for entire state and now I want to know how can exclude markers in a certain city? Say I am displaying a map of Indiana and want to exclude Indianapolis.
I have a rough idea where I can select the points and some how check if they are between a certain range but could someone elaborate on this with a more specific example or is there a better approach to this?
What you need is something called Reverse Geocoding, which will give you result of street name, city name and country name, given longitude latitude example.
I will do these steps :
Iterate all the marker and "reverse geocoding" the marker lat-long.
Check city result of the "reverse geocoding".
If the City is not inside your accepted cities, remove the marker.
