Method for the perspective display of a part of a topographic map, and device suitable for performing such a method

摘要

A method and device for the perspective display of a portion of topographic coordinate information of points on the surface of the earth proximate to the current position of a vehicle travelling thereon, utilizes a coordinate transformation to generate a perspective image from an apparent point of view above and behind the vehicle in a viewing direction, which, with the direction of travel of the vehicle, defines an imaginary plane which is perpendicular to the surface of the earth.
