https://{host}/gis_geocode?coords=[{"lon":<double>,"lat":<double>}]&city_radius=<uint>&

Parameters
| Name | Description |
|---|---|
| coords | array with coordinates |
| city_radius | minimal city radius, km (optional) Minimal city radius says that if no city has been found within maximum distance from unit (the previous option), then the address is bound to another city. How big this city should be to form the address, you indicate here – minimum radius of a city. This can be used to eliminate small cities from addresses. |
| dist_from_unit | maximal distance from unit, km (optional) Maximal distance from unit says that if unit is located near a road and there is a city (i.e. city, town, village) within the indicated distance, then in the address you will have the road's name and distance to the city. |
| txt_dist | metrics of maximal distance from unit (optional) |
| flags | flags of output format (see below) |
| uid | current user ID |
You can format output by digits from 1 to 5:
- 1 – Country
- 2 – Region
- 3 – City
- 4 – Street
- 5 – House
By default: 45321 (Street, House, City, Region, Country). For formatting use any of this digits five or less times. This output format is placed into flags by following algorithm: any digit is specified by 3 bits, beginning from 31 bit, it means max quantity of involved bits equals to 15 (from 31 to 17).
