Attālumu matricas serviss
The service allows you to get a matrix of distances (points between which you need to determine the distance and the time).
API URL
The request URL should match the following pattern:
https://api.kartes.lv/v3//calculate_matrix?
By default, the response is given in JSON (JSONP and XML are also available).
The HTTP GET request method is used.
- klienta_atslega: Your authorisation key.
Query parameters
The request consists of the following GET parameters:
| Parameter | Description | Possible values |
|---|---|---|
| p | Teksts, kurā iekodētas punktu koordinātas, starp kurām jāveic attāluma aprēķināšana. | Jāatbilst šādam formātam: [[x1,y1],[x2,y2],…,[xn,yn]], kur:
|
| wgs84 | Ja tiek padots šis parametrs, tad koordinātas parametrā p tiek padotas WGS84 (EPSG:4326) koordinātu sistēmā. Pēc noklusējuma koordinātas tiek padotas TM Baltic93 (EPSG:25884) koordinātu sistēmā. | |
| weight | Autotransporta pašmasa kilogramos. | |
| emergency | Ja tiek padots šis parametrs, tad maršrutēšana tiek veikta, pieņemot, ka transportlīdzeklis ir operatīvais transportlīdzeklis. | |
| noentry | Teksts, kurā padod punktus, starp kuriem braukt ir aizliegts. Ievades formāts atbilst p parametra ievades formātam. | |
| result_data_type | Nosaka atgriežamo datu formātu, ja netiek norādīts, tad pēc noklusējuma atgriež JSON. | Pieejami 3 formāti:
|
| callback | Parametrs aktuāls, ja izvēlas result_data_type=jsonp, tad šī parametra funkcija tiek izsaukta, kad dati tiek atgriezti. |
Response parameters
Atbildē tiek atgriezta pati matrica, katrā rezultāta "šūnā" pieejami šādi dati:
- Distance - attālums no punkta A uz punktu B metros.
- Time - attāluma no punkta A uz punktu B veikšanai nepieciešamais laiks sekundēs.
- Score, Direction - tehniskie parametri, kurus klients var ignorēt.
