Multimap API V1.2 Web Services Documentation - Routing
The Multimap API V1.2 Routing web service module allows you to generate driving or walking (where available) directions between a set of locations, provided as points, addresses or search criteria (which find the specific latitude and longitude for an address or search result). In addition to textual information about the route, the service returns a route vector which can be passed to the draggable-maps API to render a highlight of the route over the map.
The Multimap API Routing web service enables you to generate routes between two or more locations, specifying options such as language, optimization method, road exclusions and mode of travel.
The Multimap API can now also include information about carbon emissions in the directions it returns for journeys by road; if you wish your service to contain this additional option, please contact your Multimap account manager.
The Multimap API models routes in a structured format as described below:
| Term | Description |
|---|---|
| Route | This term describes the series of one or more route stages, each containing one or more route steps, between two or more locations. Every route has a start point and an end point and may contain one or more intermediate 'via' points. |
| Stage | This term denotes a series of one or more route steps that link any two points along a route. A separate route stage exists between every pair of points that have been specified along the route, including 'via' points. |
| Step | This term denotes a portion of a route stage containing one instruction, such as "Depart on Hazlitt Road for 0.1 miles". |
For a full description of all attributes and elements of the Multimap API route structure, please see the Route Structure page.
Please see the Notes on Response 1 section of this web page for a example of a typical route structure contained in an XML response.
Where the start or end point of a route does not correspond to a point on a recognized route network, the Multimap API attempts to 'snap' that point's coordinates to the nearest road within one kilometer. Since a location that has been 'snapped' any distance greater than this is unlikely to bear much resemblance to the location that was originally requested, the Multimap API Routing web service returns an Error code if a user specifies a location more than one kilometer away from the nearest road (for example, in an extremely rural area or out at sea).
The Routing module accepts parameters that both define the points that a route should include (up to ten)
and set various options about the route.
The route points can be specified as addresses, coordinate pairs of latitude and longitude or search criteria.
Each point must be numbered consecutively from "1" in the format parameter_n where n is the point number.
For example, a route from a coordinate point to the postcode EC4A 2DY, via the postcode SM6 0AZ, in Great Britain would be specified as:
&lat_1=51.3652&lon_1=-0.0763&qs_2=sm60az&qs_3=ec4a2dy
Similarly, to use search criteria to specify a point, you must specify a data source to search on.
This is done by including the dataSource_n parameter, (where n is the point number)
with a value as described in the Searching Parameters section
of this document.
A single-field filter parameter must also be used. So, for example:
&dataSource_2=mm.clients.[datasource1]&fieldname_2=id&operator_2=eq&value_2=2
This example would search the specified data source for a row with an identifier of "2". This search result would be used as the second route point (since "_2" is used on each parameter).
[Note: Please replace "parameter_[COUNTER]" with incremental numbers
such as parameter_1,parameter_2,...,parameter_n.
In these examples, parameter_1 is used for the first route point
and parameter_2 for the second route point.]
