Method of generation of a data base comprising topographical information on the obstacles, and data base of obstacles.

摘要

The present invention relates to a data base and a process for the generation of a data base comprising topographical information on the obstacles which are distributed in a geographical zone which is subdivided into cells. The method comprises the steps of: (i) of the topographic database from sources heterogeneous; (j) the generation of the topographic database relating to the obstacles isolated from the information collected in step (a); (k) the generation of the topographic database relating to the linear from the information collected in step (a); (i) the creation of the database of obstacles (1). each cell comprises a link to the obstacles, the coordinates in the geographical zone covered by the cell are recorded with a value of uncertainty. In particular, the invention applies to the generation of an on-board data base on an aircraft.
