Abstract: An inner fender panel for a structural fender of an automotive vehicle is disclosed. The panel includes an outer surface configured for attachment to the inner surface of an outer panel of the fender and an inner surface; the inner panel comprising a plurality of abutting inner fender panel sections that are joined to one another, each inner fender panel section having a thickness, at least two abutting inner fender panel sections having thicknesses that are different. A structural fender for an automotive vehicle is also disclosed. The fender includes a formed outer panel having a viewable outer surface and an inner surface. The fender also includes a formed inner fender panel as described comprising a plurality of abutting inner fender panel sections that are joined to one another, each inner fender panel section having a thickness, at least two abutting inner fender panel sections having thicknesses that are different.

Abstract: A method and vehicle are disclosed for surveying terrain by providing data from which three-dimensional coordinates of the path of the vehicle on the terrain are calculated. The vehicle includes two members articulated to one another and each member is supported on the surface by at least one wheel. The vehicle is positioned and the initial three-dimensional coordinates of a specific point on the first member and the initial orientation of the first member are determined from conventional surveying data. The vehicle is then moved a predetermined distance so that the second member tracks the first member. When the second member is located and oriented in approximately the initial position of the first member, measurements are made to determine the changes in the angle between the two members with respect to each of the axes.
