Measurements#
The section sets the parameters responsible for various measurements on the Web Map:
Units of length measurement (according to the selected SRS)
Units of measurement of areas (in accordance with the selected SRS)
Degree format
Coordinate system for calculating measurements
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.com.

Disabling address search#
Address search can be turned off. In that case the search will only be performed in the feature attributes of the layers added to the Web Map (except the basemap). From the control panel go to Web Map settings. Set the toggle of the “Address search” section to the off position.

Limit search area#
You can limit the search area to the Web Map’s initial extent. From the control panel go to Web Map settings. Set the toggle of the “Limit by Web Map initial extent” to the on position.

While using OSM, you can also limit the search to a particular country. In the field “Limit search results to countries” enter the code of the country using the ISO of the OSM data base: de, gb, fi etc. To find out the code, use the search on https://www.openstreetmap.org.

You can integrate Google streetview to your Web GIS and use it on Web Maps.
In the “Search panorama” section click Add and enter your API key.
