6.15.4. Address search

NextGIS Web address search is performed through one of the two data bases (providers):

• Nominatim (OpenStreetMap) - used by default

• Yandex.Maps - an external geocoder with API key

The following parameters can be set up:

• “Enable” - the search results on the Web Map will include not only the attribute data but also the address base if there are matches

• “Limit by Web Map initial extent” - the search will be performed within the extent set in the Web Map settings

• “Provider” - defines the geocoder used for address search. OpenStreetMap by default, can be changed to Yandex.Maps

• “Limit search results to countries” - while using OSM, if a country code is specified (de, fr, gb etc), the search results will only include matches from the selected country’s territory

• “Yandex.Maps API Geocoder Key” - when Yandex.Maps is selected as provider, this is the field to enter the API key. Users obtain the keys independently by signing up on https://developer.tech.yandex.ru.
