Show data on a map
You can visualize the vessels with their trajectories on a map. To do this, we first need a simple data stream from our vessels. Therefore, we can use this simple query:
| Code Block |
|---|
#PARSER PQL
#RUNQUERY
/// For the map view
out = TIMEWINDOW({
size = [60, 'MINUTES']
},
System.SanFranciscoAIS
) |
Next, we create a map. Right click on your project / folder in the Project Explorer and choose "New" → "Other ..." → "Odysseus Map". When you created the map, you should see an empty grid. Next, we will add a background map from a tile server. We have a few predefined tile-servers you can use. You should see "Map Layer" and "Map Connection" on the right as you can see in the figure below. If you don't see these, you can add them via "Window" → "Show View" → "Other" and then select them.
Future Work
The work on this topic is not finished. Here list of things that we want to add in future releases.
