Vertical Obstruction Data (ICAO Area 2)

This dataset contains data on all reported vertical obstacles located within 10km of an aerodrome. This 10km area constitutes ICAO areas 2 A, B and C. Data is available for aerodromes that have regular international operations and alternates (as listed in AIP GEN 1.2). These obstacles have been classed as either Verified or Unverified, as defined in PANS-AIM (ICAO Doc 10066) specifications for accuracy and resolution. These data sets may contain data on Active (A) Proposed (P) and Dismantled (D) obstacles.

An obstacle classed as Verified (V) meets the horizontal and vertical accuracy requirements outlined in PANS-AIM (ICAO Doc 10066) for electronic terrain, obstacle and aerodrome mapping information.

An obstacle classed as Unverified (UV) is outside the horizontal and vertical accuracy requirements outlined in PANS-AIM (ICAO Doc 10066) for electronic terrain, obstacle and aerodrome mapping information.
