Vertical Obstruction Identification

Vertical obstructions surrounding Toronto’s Pearson Int’l Airport

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.

3-D Airfield Feature Extraction

Passenger Terminal Chennai Int’l Airport, India

VGW Geospatial is one of the few companies that can extract airfield features from stereo imagery to create 3-D airfield maps.  We use a system that includes BAE’s Socet GXP and Socet for Arc tied to ESRI’s ArcGIS Desktop 10.x software to create 3-D features.  We also use ESRI’s Data Reviewer and other tools ensure attribute data and topology are accurate. We provide deliverable products in shapefile, ESRI file geodatabase, or Google Earth (KML) formats. Shapefiles are the most common open data standard mapping deliverable, while the ESRI file geodatabase is probably the most widely used.

VGW Geospatial has been producing 3-D airfield maps for the past 4 years and has completed 58 airfields all across the globe.
