VGW Geospatial has been locating, documenting, and mapping vertical obstructions for one of our many customers. Identifying vertical obstructions improves the safety of flight for our DoD and civilian aircrews as they transit numerous countries across the globe. The red dots on the above screenshot represent powerline pylons and the blue dots represent light standards either along roads or within athletic areas.  Every dot on the map represents an obstacle that is taller than 50 feet.  Most are between 50 and 100 feet, but there are occasional vertical obstructions that reach up to 1,000 feet or more.  We use a proprietary process to determine the location and height of each vertical obstruction, assuring accuracy and quality of the data we create. If these remain unidentified they create a substantial risk to our aircrews. The work we do eventually makes it into FAA and DoD flight charts to help promote safety of flight.
