Obstacle data sets

Area 1 and Area 2 data sets of obstacles penetrating the aerodrome Obstacle Limitation Surfaces (OLS) are collected and published according to ICAO Annex 15 requirements.

Data subjects:

The geographical scope of the data sets is FIR EPWW for the Area 1 obstacle data set and the following aerodromes for the Area 2 obstacle data sets: EPBY, EPGD, EPKK, EPKT, EPLB, EPLL, EPMO, EPPO, EPRA, EPRZ, EPSC, EPSY, EPWA, EPWR, EPZG. The spatial reference system is WGS-84 (EPSG: 4326) for the horizontal reference system and Kronstadt-86 for the vertical reference frame.

The obstacle data se contains the following data features (if applicable):

Obstacle identifier, Location, Local language obstacle type, Lighting, Marking, Obstacle type, Data source identifier, Identification of the data
