Abstract
A method of generating an image of a volume ahead of an aerial vehicle is provided. The method comprises determining a position of the aerial vehicle and generating a terrain image corresponding to ground features correlated to the position of the aerial vehicle. Obstacle data pertaining to a set of obstacles ahead of the aerial vehicle is determined with a forward looking sensor. An obstacle overlay image is generated and overlain onto the terrain image to generate a composite image.
