CAE – Clipping Road Networks

CAE used FME to generate global lightmap overlays for realistic night scene simulation for civil aviation training.

Using the graphical user interface in FME Desktop, they created a workspace that clipped roads from OpenStreetMap to illumination zones from DMSP-OLS Nighttime Lights, populated points along the road, converted it to raster which they processed with ImageMagick, restored the georeferencing, and combined the tiles.

FME replaced the old manual, time consuming process which would not have been achievable within the project’s 6 week deadline. It also increased the accuracy of the output, replacing randomized lighting with realistic night view of cities, and roads accurately lit and usable for aeronautic navigation purposes.

Founded in Canada in 1947, CAE has the largest installed base of flight simulators globally, training 100,000 pilots and crewmembers annually, with an annual revenue of $2.1 Billion.

“We have 8,000 employees based in 30 countries, and supporting all of that there are 4 people on the GIS team. So FME and automation is a really important thing for us.” -- Joanna Hobbins, CAE
