Our Reverse Geo Web Service allows you to return the distance from your current location to the nearest known location within a provided list, or in other words, create a ‘dealer locator’. Traditionally, Reverse Geo Web Service (RGWS) returned the nearest valid address to the input (starting location) which was a latitude/longitude pair and is commonly used for disaster relief mapping or emergency location applications. The ‘doLookupFromList’ feature allows the developer to instead obtain the nearest valid address from a predetermined finite list of valid addresses. Example applications might be to help customers find the closest healthcare clinic or a particular coffee shop to their current location.
Prerequisites: The input starting location can be defined (in addition to the default set of lat/long coordinates) by a Melissa Address Key (MAK) – a unique identifier given to every valid U.S. address. The provided list of input locations to be looked up must be a list of MAKs and a unique identifier for each. Therefore, to use this feature, one must first convert a list of valid addresses to obtain their respective MAKs. Using this feature requires the request to use the JSON format.
