I'm using Mapbox in a web app. I have functionality where a user inputs a zipcode and it should display on the map then do some other stuff with the data. All I'm trying to do right now is convert the zipcode to latitude and longitude to display the marker on the map and log the coordinates. Is there a way to do this in the Mapbox API? If so I can't seem to find it. If not, is there another easy way to do this?
Mapbox has it's own geocoding API in public beta:
Geocoding requests are queries composed of location text or lat/lon coordinates that can be used to find corresponding place data. A geocoding request includes a geocoding {index} in requests which specifies the dataset to use to find place data.

I am using Mapbox GL JS to show certain location marked on the map.
I need to set location through JavaScript code and I don't know the lat and long coordinates, I only have an address in string form (example: "address, city, country" or some similar format).
I have searched a lot on the internet, but the only way that I have found for doing this in Mapbox GL JS is by using Geocoder input control, but I don't want to input location through it, I want to set Address through code and then have it marked on map when the map loads.
Is it possible to do this in Mapbox GL without knowing lat and long coordinates? How can I do that?
Thanks in advance! Best regards!
You can use the Mapbox Geocoding API without the Geocoder control. You have to compose your url (and encode it).
Always consider you could get more than one result in the featureCollection response depending your params, so finally you have to refine the results with some of the attributes allowed such as proximity and limit. At the beginning is a bit of try and error task, but after some practice it's quite accurate.
Here you have an example url for the address 123 Main St Boston MA 02111, filtering the results in United States only.
https://api.mapbox.com/geocoding/v5/mapbox.places/123%20Main%20St%20Boston%20MA.json?country=US&access_token=pk.eyJ1IjoianNjYXN0cm8iLCJhIjoiY2s2YzB6Z25kMDVhejNrbXNpcmtjNGtpbiJ9.28ynPf1Y5Q8EyB_moOHylw
This will return 5 streets in the Massachusetts state.
I recommend you to read the documentation in forward geocoding, and also the section on address geocoding format to compose properly the url.
I am new to angularJS, I use the ngAutocomplete to get the locations from google service. It gives me the latitude and longitude whenever I select a location.
Now, I want to get the area and location name from selected latitude and longitude by reverse geocoding service.
I want to use the googple javascript API in ngAutocomplete module, so if user selects a location then It will return the area and location name too.
Thnanks
You are may be asking about Reverse Geocoding to get the detail information of location.
You can get the enough information about the Reverse Geocoding from

Thanks.
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.
So, I have some experience with Google Maps API, and have read some questions similar to mine around here, ie. Google Maps API - Getting Street Coordinates
Now, what I need to get done is, To query Google Maps API with a Zone argument, and get its coordinates as response (preferably in JSON format), queries should be performed within one city only.
Let's say that city is Medellin, Colombia (coords: lat: 6.236165; long: -75.575262), And that my query(zone) is: "Poblado" (a district inside Medellin), As a result of such query, I'd like to have its coordinates returned.
How can I accomplish this task?
Please, help me,
As always thank you in advance,
Sincerely,
You can use component filtering of Google Geolocation API.
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 :)
