Geo-Visualization in FoodChain-Lab
Tasks
- Use the following workflow: https://github.com/SiLeBAT/BfROpenLa….
- Visualize the delivery network in the GIS mode of the Tracing View.
- Select all stations in Poland and check out where these stations are located in the Graph mode.
Step 1

Step 2
- Now you should see a graphical representation of the delivery network.
- To switch to the geographical representation click Switch to GIS in the upper right corner.

Step 3
- The country borders, which where read from a shapefile, are used for geographical visualization.
- To zoom to a certain area of the graph select “Transforming” as Editing Mode and zoom/move the graph by using the mouse wheel and the left mouse button (works as in Google Maps).

Step 4
- If you are online, you can change the type of visualization.
- Select e.g. “Mapnik” as GIS Type.
- Now you should see a visualization with OpenStreetMap data.

Step 5
- We can now select certain stations based on geography.
- Select “Picking” as Editing Mode and select all stations in Poland by dragging with the left mouse button a rect around the stations.
- The selected stations are now colored blue.
- Switch back to the graphical view by clicking Switch to Graph in the upper right corner.

Step 6
- The blue stations are the ones you selected in the geographical view, since changes you make in any of the view are automatically applied to the other view.
- That makes it easy to switch back and forth between both representations and use the benefits of both.

Step 7
- Lets now select a certain “cluster” in the graphical view and see where the stations are in the geographical view.
- So select the “cluster” in the red circle and click Switch to GIS.

Step 8
- As you can see the stations of the cluster are located all over France.
