. The paper reveals the photogrammetric methods of the aerodrome obstacle data collection and assessment in accordance with the International Civil Aviation Organization (ICAO) requirements. High artificial or natural vertical objects (obstacles) near a runway can cause accidents during aircraft take-off and landing. There are a series of limitation surfaces defining allowable obstacle heights. Identification and assessment of obstacles extending above the limitation surfaces are important steps for aerodrome certification. To this end, the periodic aerodrome obstacle survey procedure is implemented mostly by ground geodetic methods. The goal of the research was to develop the technology for remote and effective obstacle identification and assessment processes using remote sensing stereo imagery. The photogrammetric methods were based on the three-dimensional vector models that were integrated into the stereo pair of satellite and aviation scanner images. The obstacle extends above the limitation surfaces evaluated in a semi-automatic mode, mathematically and visually controlled. The advantages of the stereo photogrammetric methods are discussed. The ecological aspects of precise evaluation of forested areas as critical obstacles considered. Examples of the implementation of this technology for aerodromes of the Republic of Belarus are given.
