I am having latitudinal and longitudinal position of around 500,000 bridges and I want the elevation of those bridges using the latitude and longitude coordinates of this bridges. I wrote a script in c# to parse elevation for all the 500000 bridges using the elevation API from the google. I generated google key with my account. Also, I enabled the billing for this account , but after few 100 request, I get an error
We're sorry...
... but your computer or network may be sending automated queries. To protect our users, we can't process your request right now.
See Google Help for more information.
I read the google api limit usage and it says that I can make upto 100000 request a day with billing enabled.
How to parse the elevation for 100000 bridges in a day?
You have hit a TOS issue..10 e to be exact:
No mass downloading. You will not use the Service in a manner that gives you or a third party access to mass downloads or bulk feeds of any Content. For example, you are not permitted to offer a batch geocoding service that uses Content contained in the Maps API(s)

Google references this:
https://developers.google.com/maps/documentation/javascript/geocoding
And states:
The per-session rate limit prevents the use of client-side services for batch requests, such as batch geocoding. For batch requests, use the Geocoding API web service.
However, when you go to the Geocoding API web services page, I see no reference to batch processing. The above sentence infers that you can do batch processing. I need to send a large number of addresses to get lat and longitude, but doing individual calls for each address is taking extremely long periods of time and need a more efficient method. Hopefully, a single batch call to send all the addresses.
Any ideas of how to batch process addresses on google to get lat and longitude?
I have seen this Google Batch Geocoding API
However, it states you can not which is not what the above google statement infers.
Per the Geocoding API web service documentation:
Other Usage Limits
While you are no longer limited to a maximum number of requests per day (QPD), the following usage limits are still in place for the Geocoding API:
50 requests per second (QPS), calculated as the sum of client-side and server-side queries.
You are just limited to 50 requests per second and have to pay for them (after you use up the $200 credit)
The best way I found to solve this problem is to use the Directions API with up to 27 destinations (origin, destination and 25 waypoints) and get your geolocation for the response legs. The position accuracy is slightly lower than in the geocode case from what I observed, but it is still a great tradeoff.
In the worst case you will have to call the Directions API twice when one or more addresses are not found in your call. The good thing in this case is that the Directions API will give you a response with the geocoded_waypoints which will specify the NOT_FOUND locations with a geocoder_status. After that, you can eliminate the bad ones and call again.
There are currently no available feature for a Geocoding API to handle multiple address at a single call, however, you may implement the batch process via cURL, by doing this, you can call multiple requests at once automatically. Implementation will be up to your use case as well.
I would like to develop a service, using Google Distance Matrix API, where a user can enter their current location and a map will be displayed showing how many other users from their group have addresses in the same general area. For privacy reasons, I do not want to show any other details (location, name, address etc.) of those other users just the number of people.
In order to ascertain this information I was intending to make a call to the API and displaying under the map of their area a message like "There are 5 other people within a 3 minute drive of your address".
Can anybody tell me whether this meets the API limitation:
The Google Maps Distance Matrix API may only be used in conjunction with displaying results on a Google map. It is prohibited to use Google Maps Distance Matrix API data without displaying a Google map
If my requirements of the API are not acceptable, could anybody suggest another publicly available API that I could use in its place?
Thanks!
Yournavigation Api gives you distance from given points.
Try this request example.
You can find their usage policy here.
They said that there are no limitations on usage, except those regarding overload:
The routing API is open and freely available for everyone under the condition that you don't overload the server. Overloading the server in this context means: more then 1 request per second for sustained periods of time. Bursting multiple requests for short time-periods is not a problem though
I have been using Google Map API on my site for about a year. I use 3 Distance Matrix requests and 1 Direction API request on each map. There is only 1 map per page.
The requests/sec for the map is about 0.02. So the Distance Matrix requests are about 0.06 and the Direction API requests are about 0.02 accordingly. But for certain hours of the day, while the map requests remain at 0.02 requests/sec, the Distance Matrix requests and the Direction API request jump to extremely high level. For example, the Distance Matrix requests can be as high as 4-5 requests/sec (or 15,000 per hour!). These huge requests start 3-5 AM and end 5-8 PM central time. The page containing the map has a page view count of about 200/hour only.
This started to happen since March. Since March I have been charged by Google $1,900 for these requests. The billing support at Google said this is a technical issue. I have searched everywhere and still not sure where to get technical support from Google.
Standard plan users are not entitled to technical support. Only Premium plan customers can get a technical support from Google.
Do you use a restricted API key? The first step might be adding an IP address restriction (web services) or HTTP referrer restriction (Maps JavaScript API) to your API key to be sure that it is used only by your application.
If you believe that API key is compromised just replace it with another one and add restrictions to new key. Once deleted the old key you will see if some part of your application is broken or not.
Update
Google introduced Google Maps Platform that replaces Google Maps Premium and Standard plans. In Google Maps platform you can file support case with Google Maps support team from your cloud project.
We have a pharmacy search application. We are trying to get the the input address from
user and find pharmacies around that address in a user specified raduis.
We are planning to geo code the address entered by user from a third party service.
After getting the geocodes we will search for pharmacies in our DB around that address and
display the results. With each result there will be a link which will open a new tab/window of maps.google.com displaying the location.
If we use the google geocoding API service to get geocodes will they charge for it ? I am not showing the map on my UI. Is that ok or violating the google terms ? Is the 2500 requests/day applicable for this scenario as well ? I am seeing that MapQuest is a service which will return only geocodes.
Thanks,
Avinash.
Double check with Google's Terms of Service, but generally they begin denying your API requests after you reach your limit. If you are a repeat offender, they may permanently prevent your IP from using their API. The limit is on the calls that you make to the Geocoding API and is unrelated to whether you display a map using their maps api. The following includes strategies for how to work within these limits: https://developers.google.com/maps/articles/geocodestrat
MapQuest just released their Open Geocoding Web Service, which is built using data provided by the OpenStreetMap community, and (currently) does not have a limit on the number of geocoding requests that can be made.
The following are the usage limits as specified by Google on their Developer Guide pages:
Google Maps JavaScript API v3 => For-profit web sites are permitted to generate up to 25,000 map loads per day
Google Geocoding API => subject to a query limit of 2,500 geolocation requests per day
Google Maps API for Business => may perform up to 100,000 requests per day
Am trying to evaluate using any one of the above for use with Visualforce on Salesforce.com (SFDC) platform [*]
I understand for a public website the requests are per IP. Now for SFDC, there could be many different Organizations on a particular server (say, NA1). So, two different companies using SFDC and Google Maps API could have an URL at https://na1.salesforce.com/something_here and their requests should be counted separately.
Will it be so? What will happen in case of each API?
[*]SFDC is a SaaS cloud for the purpose of our discussion. All users login through the same page but they could be logged into different "orgs"/"organizations" but their URLs might look similar
It's important to differentiate between the server-side and client-side limits here. The server-side geocoding api would have have the 2500 limit enforced across the shared Salesforce instance based on how many machines the requests come from (I assume NA1 isn't 1 huge server). Multiple organization using the free geocoding API would all share the same server-side geocoding limit. I've actually run into the same limits using Google's own App Engine platform, where a bunch of applications share the same outbound IP address.
For any sort of guaranteed performance you'll need to send the queries from your own server or go the Maps for Business route which lets you authenticate your queries to get those higher limits.
Client-side geocoding via the JavaScript API doesn't have these server-limits, so if users do any sort of action to trigger a geocode or two using the JS API is the best route.
You can already create your own "bucket" to track your 25K map loads per day by signing up for an API Key.
This question on SO addresses the geocoding API specifically being run from a visualforce page directly, Salesforce: Google maps query status 620 G_GEO_TOO_MANY_QUERIES and it does seem to mean that without a key the limits are shared. I would suspect that unless you plan on giving the app away that you are working on, you will pretty much be forced to pick up an upgraded API key. One thing you may want to look at to work around this is hosting the maps portion in another location, and iframing it into Salesforce.
