I had a little try and learned that it is possible to decorate for example the segments of polygons with arrows. But when it comes to Bings use case, I don't believe OpenJUMP can handle rule based styling for decorations, that is, "put arrows to lines where oneway=yes". It always decorates the whole layer. Creating a new layer from features having "oneway=yes" and decorating that with arrows might lead to map appearance that is close to what is wanted. If data comes from PostGIS database layers should be easy to create by queries, also the turning restriction layers. Of course there must be suitable attributes which can be used in queries.

But This probably doeas not work for polygons. No clue about the left-turn thing. Easiest is really to make some attribute definitions. stefan Nacho Uve schrieb: > Hello, > > Maybe you can use one Arrow Line Style for the line representation.
