Editing tool and in game comparison in FSX

The picture below is above EDDF the Cologne-Bonn Airport (one of my favorites) you can see the airport buildings, taxiways, aprons, the taxi paths on the aprons as well as a vehicle path for refueling. These are all set up in tool picture below.

Here is a top down view of the tool used to edit Vector and Raster data, such as roads, taxiways, DEM, Landclass Rasters, and even draw polygonal buildings which can be layered to make more complex 3d buildings.
