Mapzen Search is a modern geocoding and place search service based on [Pelias](https://github.com/pelias/pelias), an experimental, open geocoder from [Mapzen](https://mapzen.com) and powered by open data. It's used to transform the way people talk about places - with names and addresses - into geographic coordinates, and to translate geographic coordinates into recognizable names of places.

> - quickly localize your users so they can discover locally relevant content.
|
||
|
|
> - provide a super-fast typeahead solution which feels intuitive for non technical users.
|
||
|
|
> - improve your database by adding geographic columns, such as `home_city` and `country` to your users table.
|
||
|
|
> - store numeric co-ordinate data instead of strings, for later use in reporting, analytics and machine learning.
|
||
|
|
> - improve existing geographic data by augmenting it with information about the enveloping `country`, `city` or `state`.

|
- Forward Geocoding for Addresses + Venues: Used to find a particular place based on the rules of an address, or the name of a landmark or business
|
||
|
|
- Forward Coarse Geocoding for Neighbourhoods, Localities, regions, and countries: Used to find and localize a service to a particular area or region. Searches only for these places, but with worldwide coverage
|
||
|
|
- Restricting searches to a known area or radius
|
||
|
|
- Focusing a search: Searches all known places, but prioritizes places closer to the user (when the user's current location or approximate location is known)
|
||
|
|
- Autocomplete searches for forward geocoding: Allows a developer to build interfaces where an end-user can search for places and match against Mapzen Search's data in real-time
|
||
|
|
- Limiting results to a particular country: Allows the scoping of results to a particular country
|
||
|
|
- Reverse geocoding addresses + venues: Tries to find the name/address of the closest matching place to a geographic coordinate pair (a longitude and latitude). This can be used to take abstract location data (e.g. an end-user's device location) and find the closest address (often used in a weather or deliver app on someone's phone)
|
||
|
|
- Coarse reverse geocoding: Converts a geographic coordinate pair into the regional hiearchy for that particular place (e.g neighbourhood > locality (city/town) > Local Administrative Area (County, Prefecture) > Region (state/province) > country). This can be used to determine the general region of geographic data and can be quite useful in filtering for places in non-geographic databases that represent things that happen in places
