Abstract: An exercise device includes an axial member, a rotating apparatus, a variable resistance apparatus, and two handle assemblies. The axial member defines a center axis of a central assembly of the exercise device. The rotating apparatus is configured to rotate about the center axis and includes a surface interfacing member, a hub positioned around the axial member, and a plurality of spokes. The variable resistance apparatus includes a resistance member that exerts resistance to the rotation of the rotating apparatus, and a user control device operable to change a magnitude of resistance exerted by the variable resistance member. The two handle assemblies are positioned on opposite sides of the hub.

Abstract: A geospatial modeling system may include at least one geospatial information database to store stereo-geographic image data and geographic feature data. A processor may cooperate with the geospatial information database for generating cost coefficients defining a three-dimensional (3D) cost cube using image matching operators based upon the stereo-geographic image data, adjusting the cost coefficients of the 3D cost cube based upon the geographic feature data to generate an adjusted 3D cost cube, and generating a geospatial model based upon solving the adjusted 3D cost cube, e.g. for a best cost surface. The system and method provide an integrated approach to creating a geospatial model using available data from multiple sources.
