I wanted a free web service to get cities list and found geobytes. Its good. I wanted to know What is the meaning of 50000 request? On every key pressed it makes a HTTP request.So do they count this way?
but if you expect to be performing more than 50,000 requests per day (your average unique visitors X 5), then please tell us
Anyone who has used this please help.
I would imagine what it means is that going over 50,000 requests can be penalized in someway. A key press is not a request - but entering a city and fetching that cities' details would constitute 1 of the 50,000 requests.
Hope this helps.
I am the author and administrator of Goebytes'AutoCompleteCity API and there is now no practical limit to genuine use, and the reference to 50,000 lookup per day has been removed from the web site. I say practical, because it does have DOS attack prevention measures, but as the API is intended to be called from the browser (as opposed to a server - for that you would use the GetCityDetails API) its DOS protection measure of "1024 look ups per IP Address, per hour", should never cut in under any circumstances that I can imagine.
I'm looking for a United States Address Validation web service, as the title says. Also:
I don't need maps
I don't need Geo coding
I do need:
Validation that an address is real
Address parsing
Google's Maps / Bing Maps seemed good, but won't work for me because of these:
Prohibits use if not plotting points on a map image
Low request limits (100,000 / day) for premium account. I need more like 1,000,000 / day
Does Geocoding, which I don't need, which is resource intensive, which means it's slow
Any suggestions?
Maybe USPS?
https://www.usps.com/business/address-management-products.htm
use FedEx's API. They have an API to validate addresses.
Also:
https://webgis.usc.edu/Services/AddressValidation/Default.aspx
You can try Pitney Bowes “IdentifyAddress” Api available at - https://identify.pitneybowes.com/
The service analyses and compares the input addresses against the known address databases around the world to output a standardized detail. It corrects addresses, adds missing postal information and formats it using the format preferred by the applicable postal authority. I also uses additional address databases so it can provide enhanced detail, including address quality, type of address, transliteration (such as from Chinese Kanji to Latin characters) and whether an address is validated to the premise/house number, street, or city level of reference information.
You will find a lot of samples and sdk available on the site and i found it extremely easy to integrate.
You could, in theory, run desktop software and plug into any kind of API it provides, but then you become responsible for things like uptime, data updates, and associated overhead. You may also run into issues with the software threading model--is it multi-threaded or single-threaded software? You don't want to find that out in production.
There are a handful of web services out there that can verify US-based addresses, including the USPS official web service. The USPS one is very limited in the fields that it returns. For example, if you're looking for the "delivery point" which is used to make a full barcode, the USPS API doesn't return that information. I believe the USPS web service also limits the number of queries that you can perform, although I don't remember the exact limit.
A few things that you'll want to look for in a web service include the price (obviously) as well as geo-distribution of their servers. If a company has all of their servers in one location and that data center goes offline (which can and does happen), you're left out in the cold. If they have multiple physical locations, it can help to prevent unnecessary outages. Also, you'll want to make sure that the service call returns all necessary fields as per your requirements--like delivery point code, barcode, and DPV code (which tells you how deliverable an address is).
Lastly, you'll want to determine how you feel about interacting with the company. When you call them on the phone, are they responsive and concerned about your needs? Or are you talking to some front-line person that can't answer questions and is only able to gather information about your company size and revenue so they can evaluate how big of a fish you are and determine which salesman gets to call you back. Can you talk to the engineers that wrote the web service on the phone or via email?
There are a few choices out there and you'll have to choose the one that best fits your requirements and unique situation. Do a Google search to find a list of companies. In the interest of full disclosure, I'm the co-founder of SmartyStreets. We have an address verification web service API called LiveAddress. You're more than welcome to contact me directly with questions on my personal Twitter account or the company Twitter account.
Sorry for so noobish question but how can I do it with C++? I need to get country names and their 2-letter or 3-letter ISO codes (or whatever it's called) using a given IP address. Is there any way to do this easily?
The only two ways I found are to use GeoIP C library or to download a free database but is there something more dynamic? I mean, is there a free web-service with up-to-date db I can utilize for my purpose using curl or something?
Thanks in advance.
MaxMind.com exposes a set of web services for geolocation. They're not free, but cheap per lookup.
One of my clients uses their city-level lookup service, with each result cached for a reasonable period (from memory, 2 or 3 weeks), since IP address blocks don't change location that often.
The application also counts the number of actual lookups to send an admin notification when the number remaining in the subscription gets low, so it can be topped up manually.
I also use the downloadable database in several applications, with a scheduled update process to keep it up to date.
http://www.hostip.info provides an API.
I have a web-based interface for handing invoices, customer records and other transaction records which interacts currently with a database of all the aforementioned stored upon the same machine. As you can imagine, this is quite a simple set-up consisting of a web-app (PHP) and a database (MySQL). However, the ideal scenario is to keep the records on the machine they are currently on (easy) and move the web-app to another server within the same network (again, easy) ... but in addition, provide facilities on a public-facing website for managing accounts by customers and so forth. The problem is this - the public-facing web server is located in a completely separate location as it is a dedicated server provided by a well-known ISP.
What would be the best way to enable the records to be accessible from this other server whilst ensuring that all communications are secure. Speed is not a huge factor, although any outages on either side should be handled gracefully. Initially my thoughts went towards web services (XML-RPC/SOAP/Hessian), but these options seem to present difficulties (security being the main one, overcomplexity as well).
The web-app must remain PHP-based. The public-facing site is likely to be PHP-based as well, although Python (likely using Django) is another option. The introduction of any other technologies (Java etc) is not a problem, although it is preferred if they be Linux-friendly (so .NET would not be the best fit here).
Apologies if this question is somewhat verbose and vague. I am testing the water somewhat in regards to this kind of problem. Any advice or suggestions gratefully received.
I've done something similar. You can expose a web service to the internet that will do the database access, but requests to the service must match a strong hashed and salted password (which will be secured on the ISP's server in the DMZ.)
Either this or some sort of public/private key encryption scheme.
OK, this might seem a bit silly, but what if you just used mysql replication?
Instead of using all sorts of fancy web services, just have a master sql server on one machine, then have it replicate to another server that holds the slave sql server as well as the web app
How would I go about converting an address or city to a latitude/longitude? Are there commercial outfits I can "rent" this service from? This would be used in a commercial desktop application on a Windows PC with fulltime internet access.
Google has a geocoding API which seems to work pretty well for most of the locations that they have Google Maps data for.
http://googlemapsapi.blogspot.com/2006/06/geocoding-at-last.html
They provide online geocoding (via JavaScript):
http://code.google.com/apis/maps/documentation/services.html#Geocoding
Or backend geocoding (via an HTTP request):
http://code.google.com/apis/maps/documentation/services.html#Geocoding_Direct
The data is usually the same used by Google Maps itself. (note that there are some exceptions to this, such as the UK or Israel, where the data is from a different source and of slightly reduced quality)
Nothing much new to add, but I have had a lot of real-world experience in GIS and geocoding from a previous job. Here is what I remember:
If it is a "every once in a while" need in your application, I would definitely recommend the Google or Yahoo Geocoding APIs, but be careful to read their licensing terms.
I know that the Google Maps API in general is easy to license for even commercial web pages, but can't be used in a pay-to-access situation. In other words you can use it to advertise or provide a service that drives ad revenue, but you can't charge people to acess your site or even put it behind a password system.
Despite these restrictions, they are both excellent choices because they frequently update their street databases. Most of the free backend tools and libraries use Census and TIGER road data that is updated infrequently, so you are less likely to successfully geocode addresses in rapidly growing areas or new subdivisions.
Most of the services also restrict the number of geocoding queries you can make per day, so it's OK to look up addresses of, say, new customers who get added to your database, but if you run a batch job that feeds thousands of addresses from your database into the geocoder, you're going to get shutoff.
I don't think this one has been mentioned yet, but ESRI has ArcWeb web services that include geocoding, although they aren't very cheap. Last time I used them it cost around 1.5cents per lookup, but you had to prepay a certain amount to get started. Again the major advantage is that the road data they use is kept up to date in a timely manner and you can use the data in commercial situations that Google doesn't allow. The ArcWeb service will also serve up high-resolution satellite and aerial photos a la Google Maps, again priced per request.
If you want to roll your own or have access to much more accurate data, you can purchase subscriptions to GIS data from companies like TeleAtlas, but that ain't cheap. You can buy only a state or county worth of data if your needs are extremely local. There are several tiers of data - GIS features only, GIS plus detailed streets, all that plus geocode data, all of that plus traffic flow/direction/speed limits for routing. Of course, the price goes up as you go up the tiers.
Finally, the Wikipedia article on Geocoding has some good information on the algorithms and techniques. Even if you aren't doing it in your own code, it's useful to know what kind of errors and accuracy you can expect from various kinds of data sources.
Yahoo! Maps Web Services - Geocoding API accurately geocodes UK postcodes, unlike Google's API.
Unfortunately yahoo has deprecated this service, you could visit http://developer.yahoo.com/geo/placefinder/ for yahoo's service
Try this: http://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=false
more info here: http://code.google.com/apis/maps/documentation/geocoding/
When you convert an address or object to a lat/long it is called Geocoding.
There are a lot geocoding solutions around. The solution right for your project will depend on the acceptability of the licensing terms of each geocoding solution. Both Microsoft Virtual Earth and Google Maps offer solutions which are free to use under a very restrictive licenses...
https://developers.google.com/maps/documentation/javascript/tutorial
Having rolled my own solution for this before, I can whole heartedly recommend the Geo::Coder::US Perl module for this. Just download all the census data and use the included importer to create the Berkeley DB for your country and point the Perl script at it. Use the module's built in address parsing, and there you have it: An offline geocoding system!
Try with this code, i work like this with addresses:
It is link in which with GET method you will send request and get lat and lng. http://maps.google.com/maps/api/geocode/json?address=YOUR ADDRES&sensor=false
For exemple: http://maps.google.com/maps/api/geocode/json?address=W Main St, Bergenfield, NJ 07621&sensor=false
1. Create your GET method.
public static String GET(String url) throws Exception {//GET Method
String result = null;
InputStream inputStream = null;
try {
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
Log.v("ExecuteGET: ", httpGet.getRequestLine().toString());
HttpResponse httpResponse = httpclient.execute(httpGet);
inputStream = httpResponse.getEntity().getContent();
if (inputStream != null) {
result = convertInputStreamToString(inputStream);
Log.v("Result: ", "result\n" + result);
}
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
2. Create method for send request
#SuppressWarnings("deprecation")
public static String getLatLng(String accessToken) throws Exception{
String query=StaticString.gLobalGoogleUrl+"json?address="+URLEncoder.encode(accessToken)+"&sensor=false";
Log.v("GETGoogleGeocoder", query+"");
return GET(query);
}
gLobalGoogleUrl="http://maps.google.com/maps/api/geocode/"
3. Call method getLatLng
String result=getLatLng("W Main St, Bergenfield, NJ 07621");
4. Parse JSONObject
Now result is JSONObject with information about address and lan,lng.
Parse JSONObject (result) with gson().
After that use lat,lng.
If you have question about code , ask.
You want a geocoding application. These are available either online or as an application backend.
Online applications:
Google has a geocoding API
Backend applications:
GeoStan
Maptsraction (http://www.mapstraction.com) lets you choose between any number of geocoding services. This could be helpful if you need to do large quantities, as I know Google has a limit to how many you can do a day.
Virtual Earth does it. There is also a web service at geocoder.us
You could also try the OpenStreetMap NameFinder (or the current Nominatim), which contains open source, wiki-like street data for (potentially) the entire world.
you can use bing maps soap services, where you can reference reverse geocode service to find lat/long from address
here is the link
http://msdn.microsoft.com/en-us/library/cc980922.aspx
Yahoo! Maps Web Services - Geocoding API
You can use Microsoft's MapPoint Web Services.
I created a blog entry on how to convert an address to a GeoCode (lat/long).
Thought I would add one more to the list. Texas A&M has a pretty decently priced service here: http://geoservices.tamu.edu/Services/Geocode/
A good option if you have a pretty large set of addresses to geocode and don't want to pat 10k to Google or Microsoft. We still ended up using the returned data in a Google Map.
you are asking about Geocoder.
Google provide an API for this.
so does another provider for this.
you can see the demo of implementation in My Current Location .net
The USC WebGIS Geocoder is free and offers several API's, or you can upload a database for online batch processing.
If you need a one off solution, you can try: https://addresstolatlong.com/
I've used it for a long time and it has worked pretty well for me.
