API Key	Your unique API key. To request an API key please contact: info@maplarge.com
Latitude	Geographic coordinate that defines the north-south position of a point on the Earth's surface. MapLarge requires decimals for input data, e.g., Latitude: 38.904351
Longitude	Geographic coordinate that defines the east-west position of a point on the Earth's surface. MapLarge requires decimals for input data, e.g., Longitude: -79.517096
Address	The location information received from a reverse geocoder is often informally referred to as an “address”.
Regions Covered	The Reverse Geocoder API currently only covers addresses located in the United States (50 states + District of Columbia). However, international support is available on a custom support basis. Please contact info@maplarge.com

We also have a simple URL based geocode method to our api with a JSON response format that is useful for individual geocodes based on user input from a webpage. In the examples below, clicking on the url should "just work" with no programming required. //geocoder.maplarge.com/geocoder/jsonReverse?address=149%20Robin%20Hood%20Rd&city=Atlanta&state=GA&zip=30309&key=YOUR-API-KEY

Example Response:  { "lat":33.7977, "lng":-84.3829875, "success":true, "streetMatch":"KnownAlternateName", "numMatch":"Exact", "streetName":"robin hood rd" } //geocoder.maplarge.com/geocoder/ReverseGeocode?latitude=33.81252857107191&longitude=-84.3035888671875&callback=abc123&key=YOUR-KEY

Example Response:  abc123( { "distance":0.23071821872357665, "lat":33.812529, "lng":-84.303589, "streetNumber":3161, "streetName":"N Druid Hls Rd", "city":"Decatur", "state":"GA", "zip":"30033", "country":"USA" }); We also have a bulk reverse geocoding API. The examples below show the programmatic use. You post a file up and the response is the reverse geocoded records in CSV format. The API expects a post with one mandatory parameter, 'key' and the post body contains the CSV data. The response is CSV text.

I created a test account key for you

YOUR-API-KEY

Files require a Latitude and Longitude column header (.zip and .csv are both valid, no need for zipped=true. This also goes for our regular geocoder).

Single File

Post a CSV File and get CSV File response

string url = "<a href="//geocoder.maplarge.com/geocoder/PostReverseCSV?key=YOUR-API-KEY";">//geocoder.maplarge.com/geocoder/PostReverseCSV?key=YOUR-API-KEY";</a> string filePath = @"C:\Maplarge\Geocode.csv"; WebClient wc = new WebClient(); byte[] responseArray = wc.UploadFile(url, filePath); System.IO.File.WriteAllBytes(@"c:\Maplarge\result.csv", responseArray);

Multiple Files

Post One of more CSV files as a zip package, and get a zip package back

The optional parameter 'zipped=true' indicates that your upload format is a zipped package. We support uploading a zipped dataset of one or more CSV files, they will be returned as a zipped package.

//Zipped package one ore more files url = "<a href="//geocoder.maplarge.com/geocoder/PostCSV?key=YOUR-API-KEY&amp;zipped=true";">//geocoder.maplarge.com/geocoder/PostCSV?key=YOUR-API-KEY&amp;zippe...</a> filePath = @"C:\Maplarge\Geocode.zip"; responseArray = wc.UploadFile(url, filePath); System.IO.File.WriteAllBytes(@"c:\Maplarge\result.csv.zip", responseArray);
