I want to mark all the location available in the database on the Map.After that I want to create an API which will accept the location of the user and it will return all the marked location within a range of 500 metres.Please provide me with appropriate solution
As a first step, you can store the locations in mongodb as GeoJSON. Then you can use mongodb's geospatial queries (tutorial and related links) to return locations within the specified range. Using the returned data, you can plot markers on a map using Leaflet.js. Leaflet.js has support for GeoJSON, so you can use the returned data without much modifications.

I'm doing a little project which heavily relies on locations and my question here is...
Is it possible to use the google map API to get cities within a certain radius from a location so that I can reduce the number of times I have to query on my database before I get the results I want?
I have previously done a radius search by using the locations stored on my database and I'm thinking that if it is not possible to get the cities within radius with just the use of the google map API,
My alternative solution would be to get all locations (stored in my database) within a certain radius by filtering them via lat and lng and get all distinct localities of the returned locations.
However, results can be inaccurate. Because there can be datas stored up in my database that might not show up if it is not within radius from the location specified during radius search, despite being in the same city/locality, which is actually the filter that I want.
I am trying to build the following
Build a User Interface to search for an address using the the API provided to me with a key:
Use the Lat/Lon coordinates returned by each address to display on the map
So far I have created a map and now I need to use my API to verify the location on the map with the coordinates returned.
Any help will be highly appreciated.
I want to retrieve the nearest location to a latitude and longitude.
If I perform a get with the following url
https://maps.googleapis.com/maps/api/place/search/xml?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=false&key=MY_KEY
I am expecting it to return a JSON array.
However, I get an Access Denied result. I generated my key from the Google console.
Please let me know what I might be doing wrong.
For retrieving the current location of device you can go-through this answer and this answer.
Then get places near your location using Google's Place API and you can also refer this blog.
I am using Geocoder callback function for getting latitude and longitude value which is asynchronous.
This works great for the 1st 10 items. I will see a markers on the map as well as those 10 listed on my sidebar. However, the 11th item and beyond will not display anything. I am querying our internal database based on parameters set which often will produce 30+ rows returned in the database table which I am looping through.
Is there any way to display more than 10 addresses on google map. or is there any need to purchase any license for get additional API for geocoder .
Thanks in advance !
The Google Geocoding services are rate limited and subject to quotas (to prevent abuse), the (paid) Google Maps API for Business, does have higher limits. The usual suggestion is to geocode the loctions offline, store the coordinates in your database, then use those coordinates to display the markers.
If you can't store the locations in your database, you need to check the return value in the geocoder and delay when it returns over query limit errors. There are examples of doing that both here in SO and in the Google Maps API v3 group.
I have a google map with multiple markers.I done that using google map Geocoder with the help of this link Geocoder usage .But,it was limited to some markers only.After the limit it is showing the error as queryLimit.Is there any way to show the multiple markers on the map without any limit.It can be other than Geocoder too.Thanks
You should never use a webservice or API to get the locations every time you want to show the markers. What you need to do is store the latitude and longitude somewhere. Preferably the same place you are storing the address information. Then just use those latitudes and longitudes to generate the markers with no need to worry about query limits.
The reason you are exceeding the query limit is that you are doing the queries too fast. If you have a period between each query you can do a lot more before hitting the querying cap, but this is not a solution. You should always save the location instead of querying every time :)
