Extended geocoding

Extended geocoding returns address information and coordinates from the queried text (address) string. Unlike the standard geocoding, the API gives greater importance to postal code for ordering of results, returns match score value of the returned and allows the address to be entered as separate elements (however, it's not mandatory). To increase the chance of getting results, a multi-level approach is being used in the backend, if the first step is unsuccesful, the geocoder becomes less strict at the next steps. If it's impossible to get correct address, only the location of the populated place might be returned.

Only Baltics' addresses can be geocoded. The official Latvian, Estonian and Lithuanian address databases are being used as the data source. Navigation coordinates of the closest point of the routable road network for motor vehicles are calculated using the Jāņa sēta road network.
