Traffic Network (How To)

From GeoMedia Smart Client
Jump to: navigation, search


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.

If you create new symbols with the SymbolStyleEditor you have to set the type to TrafficNetwork and then the following window opens:

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.
