Abstract

SYSTEMS AND METHODS FOR MAPPING A NAVIGATIONAL SPACE A system and method for mapping a navigational space. The method comprising: defining a base iayer of three-dimensional (3D) polygons that is distributed over a base of the navigational space, wherein a height of each 3D polygon of the base layer is the same; and defining one or more upper layers of 3D polygons that are above the base iayer of 3D polygons, wherein each 3D polygon of the base layer and the one or more upper layers demarcates a distinct volume of the navigational space.
