Abstract: A system and assembly including a modular edge compaction wheel with multiple separable sections to form edges of a substrate (e.g., an asphalt mat) at differing depths. After forming a portion of the substrate edge at an initial depth, sections of the modular edge compaction wheel assembly may be attached by stacking and fastening the sections together for forming another portion of the substrate edge at a greater depth. The edge forming assembly may include an activating mechanism to extend and retract the modular edge compaction wheel assembly.

Abstract: A method for displaying arrays of digital image data on a display monitor as a continuous image includes determining nonlinear corrections for each of the arrays of digital image data. Each nonlinear correction may be based in part on a location of the imaging device used to capture the array of digital image data relative to a location of the perspective center from which the array of digital image data will be displayed on the display monitor. The method also includes transforming each array of digital image data using the corresponding nonlinear correction. The method also includes displaying the arrays of corrected image data on the display monitor to produce a continuous display of the scene captured by the imaging device, where relative sizes and positions of objects in the scene are substantially reproduced in the display of the scene.

Abstract: A method and system for producing digital orthophotos from imagery acquired as full or sparse stereo. The orthophotos can be produced in a variety of map coordinate systems without the need to convert or recompute DEM or photogrammetric solution data. In one embodiment, a two-dimensional, planimetric free-network solution, utilizing arbitrary datum definition constraints, is used to provide a transitory coordinate system that is used to facilitate the image measurement process. It is utilized as a preliminary step to refine apriori block layout information to facilitate point picking and to provide general quality control capabilities before undertaking a rigorous 3D photogrammetric adjustment. In place of a general map conversion transformation, an identity transformation can be used, so that map coordinates and world coordinates are identical.
