Traffic Network (How To)
One possibility for the Interpretation (see here) of a feature is called TrafficNetwork. This allows a smart way of displaying different street levels (for example tunnels, cross bridges and so on). So there are some advantages of the Street Network Symbolization:
- Multiple polyline feature classes (even of different tables) can be included properly.
- No limitation of GeoMedia Smart Client standard usage (queries, turn on/off and so on) of a single feature in a street network.
- Every line segment is defined per z-values.
- Works with every data, which contains z-level data (for example NAVTEQ or OpenStreetMap).
- Display considers scale ranges on the fly.
- SE definitions are supported.
- Cache, Live and Caching on Demand are fully supported.
The following steps represents an example, how to visualize the TrafficNetwork symbolizer:
1. You need z-level values for the traffic network symbolizer. This data can come from any provider, which offers you z-level values (like NAVTEQ or OpenStreetMap), but you can also have your own feature table in the database contains z-level values.
2. Define new symbols, which covers all possible types in your traffic network table.
You have to add a TrafficNetwork in your scale area (right click on the scale and then click on TrafficNetwork). Then on the right hand side a few options can be set. Two of them are ZLevel: and Displaylevel:. The first one defines the z-values (either a static value or a dynamic value [from database]).
3. Set the Interpretation of the desired feature to TrafficNetwork.
4. Define thematic legend entries for the streets feature. How to create thematic entries see here.
5. (optional) Editing the z-levels of the street network:
- Type the values into the database directly (if you know which street is on which z-level).
- Write a workflow, so you can edit the z-level on the fly in the GeoMedia Smart Client.
