Hi there,

Every once in a while we get asked for “how can I extract complete data from a map through a single request or a bunch of requests?”… This applies e.g. to the ferry connections as in this customer request:

I am curious whether it would be possible to retrieve the whole list of COMBINED_TRANSPORT with a single getSegments operation request? Currently I am able to retrieve a list of combined transport segments surrounding a specific coordinate, but it would be great if there was an option to get the whole list.

Well: there are two reasons why this is not implemented by design:

• Extracting data from a map is limited due to licensing conditions of map/data provider.
• Therefore gathering ferry connections is limited to a specific maximum number (keep the interface/performance reasonable).

I know some compareable requests of clients such as:

• Can I retrieve all postcodes of a country together with their city names?
• Can I retrieve all streets of a city?
• Can I retrieve a list of all parkings in the map?

Usually the functional request behind these questions can be resolved easily once we discussed the usecase. In the combined transport request above we assume the client wants to build a UI where the user can select a specific ferry connection by adding a meaningful intermediate point. So for this requirement a local search around a preferred port/harbour would be sufficient. Test this showcase.
Best regards,
Bernd
