API URL

The request URL should match the following pattern:

https://api.kartes.lv/v3//speed_limit?

The response is given in the JSON.

The HTTP GET request method is used.

Query parameters

There are three ways to define coordinates:

Parameter Description
lat Latitude coordinate in the WGS-84 projection (EPSG:4326)
lon Longitude coordinate in the WGS-84 projection (EPSG:4326)
x x-coordinate in the TM Baltic93 CRS (EPSG:25884).
y y-coordinate in the TM Baltic93 CRS (EPSG:25884).
p Array of coordinate pairs (e.g., [[510427,6308643],[514276,6304829]]).
wgs84 Should be used in case of p parameter, if the WGS coordinates are used.

Response parameters

The response consists of an array of objects, each of them having two elements. Each element consists of following parameters:

Parameter Description
name Street or road name
populated_place Populated place (city, town or other settlement; only for named streets)
teritorial_unit Territorial unit (only for named streets)
administrative_unit Administrative unit (only for named streets)
surface Surface
speed_limit Speed limit
is_populated_place Is this a populated place?
distance Distance to the closest road segment
