ClearFlite uses soft-copy photogrammetry, GIS, and geospatial analysis to identify and collect vertical obstructions.

• Identifing and inputting runway end points.
• Automatically building 3-D Obstruction Identification Surface (OIS) model.
• Building a reflective surface elevation model – similar to a lidar database.
• Intersecting the OIS and the elevation model – this automatically identifies terrain obstacles.
• Extracting the vertical obstructions in stereo – attributes are automatically applied to obstructions.
• Exporting data to GIS/Visualization application. (Yellow polygons show obstructing terrain and symbols show vertical obstructions.)
