Figure 5 shows the process for converting custom map overlays. It begins by using the Geospatial Abstraction Libraries. There are three steps at this stage: (1) the user's geospatial-referenced map files are created, (2) These files are converted to geotiff format, and (3) the files are then transferred to the Python script, where they are renamed. Using the nvidia tool kit, the files are compressed to dot dds format. Finally, the files are moved to the proper Flight Gear folder. End Figure 5.
