Systems and methods for identifying and uniquely displaying ground features (terrain/obstacles) that are shadowed from an aircrafts radar system. An example system includes one or more aircraft information, sources, a database that stores three-dimensional terrain/obstacle data, a display device, and a processor in data communication with the one or more aircraft information sources and the database. The processor receives aircraft position, heading and altitude information from the one or more aircraft information sources. The processor projects a vector in a three-dimensional digital space onto the three-dimensional terrain/obstacle data stored in the database based on the received aircraft position, heading and altitude information to determine if the projected vector intersects more than one terrain feature. If the feature is intersected by the vector and the feature is further away from the aircraft than another feature that is also intersected by the vector, it is uniquely displayed on the display device.
