Marble/OnlineRoutingImplementation

This page lists more concrete steps to integrate online routing support. Code is currently available at http://nienhueser.de/git/marble.git

Routing providers (done)

Support data download from

A custom paint layer which displays routing points: Start, destination, intermediate points. Waypoints, connected.
- Paint layer reuses the selection model of the routing instruction list view
- Source, destination and via points are movable in the map
- Instructions are shown in the mapping when clicking on the corresponding waypoint
Paint layer is included in Marble's model

Merge UI in MarbleControlBox: Search via runners and routing can be done from the same widget similar to how Google Maps does it
Default Search is pretty much the same, but has a "Add destination field" button which adds more search widgets (each representing one position to be included in the route)
Search results are shown in the list view. The selected search result is kept track of and taken as the source/destination point.
Once all routing points are known (user selected a search result or clicked on the map for both routing source and destination and intermediate points, if any), the "Get Directions" button can be used to fetch routing instructions from the current routing provider
Routing results are shown in the same list view as marble runner search results
Reverse geocoding via osm nominatim
Route instruction localization
Route preferences: By car, by bycyle, ... avoid highways, avoid toll roads

Ask the oxygen guys if they can help out with some icons:

Check which routing providers can be shipped / enabled by default
OpenRouteService allows non-commercial usage. Exact definition todo
Google Maps cannot be used at all (license terms)
CloudMade can possibly not be used (cumbersome pricing model)
YourNavigation is currently too limited (server often busy, routing data only for UK? No route instructions atm, only waypoints)
