sential task. Determining a route for e.g. a truck
is simple
if the road network including the legal and technic
al limitations like truck ban or weight restriction
are
known. Planning of multi-modal routes is a bit more
complex. The change of mode of transportation is o
nly
possible at specific locations. This change takes t
ime and is often subjet to additional technical or
legal
restrictions. Thus the different networks, e.g., ro
ad and rail, need to be connected.
An obvious approach for multi-modal transport plann
ing would be the use of Open Street Map (OSM) data
since it does not only contain information about ro
ads but also about trains and rivers. In this pape
r we first
present some existing solutions for multi-modal tra
nsport planning and then discuss the use of OSM dat
a in
such a process. We identify missing elements in OSM
and show opportunities for further development and
interventions.

Within these, information is stored in different layers with different levels of detail which in turn are connected by automated generalisation processes. This is still not solved satisfactorily and is, in the opinion of the author, essentially a problem of the data-model used to store geographic information.
Changing the way of storing features away from any fixed constraints concerning positional information to a lattice-oriented, topographic, tagging based way to define geographic features, it should be possible to develop a flat, scaleless geographic storage which allows the use of data of any scale.

Many other functions and applications useful mainly for web-development are overseen. By using the GeoCouch extension CouchDB can make spatial queries but the access to geodata is limited to an interface specific to CouchDB. WFS is an OGC standard defining the transfer of geodata via HTTP. Many GIS already make use of this standard.
By using "list" functions it is possible to implement a WFS Server in a CouchDB without the need of additional software. By this a standardised interface to many GIS applications is offered.

Its purpose is the matching of POIs from OpenStreetMap with a random set of points. To do so, a simplified matching algorithm is constructed and evaluated.
Furthermore, a way to support legal decisions when using OpenStreeMap data is implemented.
