Abstract (en)
[origin: WO2005031262A1] The invention relates to a method whereby a terrain elevation database can be used to calculate a distance map of the points accessible to a travelling object that is subjected to dynamic path constraints which change over time, e.g. an aircraft having an imposed vertical flight profile, said distances only being measured using the paths that can be passed by the travelling object. The inventive method employs a propagation distance transform which: (i) lists the passable paths from a target point to a source point, the distance of which is to be estimated in order to provide distance measurements; and compares the distance from the target point to the length of the shortest passable paths(s).
