Claim Text:
1. A display system for a vehicle, comprising: a data source configured to provide terrain data with detached objects that are detached from ground terrain and attached objects that are attached to ground terrain, the detached objects including a first detached object within a first column of grid points of a three-dimensional occupancy grid based on the terrain data; a processing unit coupled to the data source configured to receive the terrain data and to distinguish the detached objects from the attached objects to generate display commands for a three-dimensional view that comprises graphical elements representing both the detached objects and the attached objects, the processing unit configured to identify the first detached object when a discontinuity between a lowest group of continuously occupied points from a bottom-most level of the first column and additional occupied points within the first column exceeds a predetermined threshold; and a display device coupled to the processing unit and configured to receive the display commands and operable to render the common three-dimensional view to thereby allow viewing of the detached objects and the attached objects, wherein the processing unit is further configured to generate the display commands with a first tether extending from the first detached object to a corresponding terrain location within the first column.
