General Usage
Main Plugin
The standard GUI is launched either from the Web toolbar or the Web menu:
You'll find a shortcut to the configuration settings and the wiki here. Also, it will show you your available requests for the current period of time (usually one day) as soon as you made the first request in the current QGIS session.
Parameters
You can use all available profiles from openrouteservice, including wheelchair (only available for Europe), for the fastest or shortest route. In the Advanced dialog you can set avoidables to be considered during route finding.
Input features
As input, either map start and locations directly from the map canvas by clicking the green plus button buttons and choosing a location in the map canvas, or use Point layers to route from/to. Batch operations involving whole layers are better performed using the Processing tool. The Unique ID fields let you specify the ID's being used to identify the output features, enabling joining of output and input layers.
If you're using a layer for start and end locations, you can choose the mode. Row by row will route from each row in the start layer to the corresponding row in the destination layer. All-by-All will route each feature of the start layer to each feature of the destination layer, basically performing a matrix calculation. Use this option with care. In case you don't need the output geometries, but you're only interested in a table of the distance and/or duration, consider using the Matrix API.
Output features
For each operation a LineString layer will be output, which contains the following properties:
DIST_KM: the calculated route distance in kilometersDURATION_H: the calculated route duration in hoursPROFILE: the transportation mode being usedAVOID_TYPE: a pipe (|) separated list avoidablesFROM_ID: the values of the ID field used in theFromlayerTO_ID: the values of the ID field used in theEndlayer
