Further Features: geocode provider - Pelias
The routing engine OpenRouteService provides the geocode service Pelias.
This service requires an API_KEY. So if you want to use it, you have to register on https://openrouteservice.org/dev/#/home. You can get a token with an API_KEY for free, which allows up to 1000 Geocode requests a day. You have to put one line in your “Pelias.cfg” configuration file:
API_KEY=<your_registered_API_KEY>
Forward search
The implementation for the Pelias search engine defines a circle of 50km around the current center position of the map. Starting with zoom level 9, this size doubles with each lower zoom level. The number of result is limited to 5. This implementation is using the autocomplete API https://api.openrouteservice.org/geocode/autocomplete As soon as the search text length exceeds 5 character, the search will be started.
If we search for the “Hauptstraße street, we don’t have to type the full name. Already the search string “Haupts” contains as the first result already the “Hauptstraße” street in Heidelberg.
Nevertheless, if you try to combine incomplete terms, e.g. “Haupts Hei” - then the search doesn’t give you any result!
Reverse Search
Pelias also supports the reverse geocoding search via https://api.openrouteservice.org/geocode/reverse
A long press on the “Haupstraße 20, Heidelberg” provides the following result:
Summary
The search results, forward and reverse are both with quite good quality.
