METHOD FOR GENERATING AIRPORT OBSTRUCTION CHARTS BASED ON DATA FUSION BETWEEN INTERFEROMETRIC DATA ACQUIRED BY SYNTHETIC APERTURE RADARS POSITIONED IN SPACEBORNE PLATFORMS AND OTHER TYPES OF DATA ACQUIRED BY REMOTE SENSORS

摘要

PROBLEM TO BE SOLVED: To provide a method of generating Airport Obstruction Charts based on fusion between interferometric data acquired by Synthetic Aperture Radars positioned in spaceborne platforms and other types of data acquired by remote sensors.SOLUTION: A method of generating an Airport Obstruction Chart is characterized by the steps of: converting data of surveyed areas into data in digital format; vectorizing the data; analyzing the digital data; generating a Digital Surface Model; comparing an initial Digital Surface Model with new data acquired in a later epoch; comparing a base Digital Surface Model with an altimetric data structure; registering and geographically referencing the Digital Surface Model; cutting an image; resampling raster models to be compared with those obtained between the initial and later epochs; detecting land changes; overlaying raster images of obstruction objects on top of an Airport Obstruction Chart in a vector format; validating new obstructions; and disseminating a new Airport Obstruction Chart.
