Abstract Efficient, accurate data collection from imagery is the key to an economical generation of useful geospatial products. Incremental developments of traditional geospatial data collection and the arrival of new image data sources cause new software packages to be created and existing ones to be adjusted to enable such data to be processed. In the past, BAE Systems’ digital photogrammetric workstation, SOCET SET®, met fin de siècle expectations in data processing and feature extraction. Its successor, SOCET GXP®, addresses today’s photogrammetric requirements and new data sources. SOCET GXP is an advanced workstation for mapping and photogrammetric tasks, with automated functionality for triangulation, Digital Elevation Model (DEM) extraction, orthorectification and mosaicking, feature extraction and creation of 3-D models with texturing. BAE Systems continues to add sensor models to accommodate new image sources, in response to customer demand. New capabilities added in the latest version of SOCET GXP facilitate modeling, visualization and analysis of 3-D features.

Wire and arc additive manufacturing (WAAM) is considered to be an economic and efficient technology that is suitable to produce large-scale and ultra-large-scale metallic components. In the past two decades, it has been widely investigated in different fields, such as aerospace, automotive and marine industries. Due to its relatively high deposition rate, material efficiency, and shortened lead time compared to other powder-based additive manufacturing (AM) techniques, wire and arc additive manufacturing (WAAM) has been significantly noticed and adopted by both academic researchers and industrial engineers. In order to summarize the development achievements of wire and arc additive manufacturing (WAAM) in the past few years and outlook the development direction in the coming days, this paper provides an overview of 3D metallic printing by applying it as a deposition method. The review mainly focuses on the current welding systems, software for tool path design, generation, and planning used in wire and arc additive manufacturing (WAAM). In the end, the state of the art and future research on wire and arc additive manufacturing (WAAM) have been prospected.

Flexible Models

Based on the automatic dynamic analysis of mechanical systems software, both rigid and flexible models of the space-swing mechanism for the superpave gyratory compactor are developed. The structural analysis shows that the length and the initial phase of cranks, and the assembling accuracy (coordinates) of some points are very sensitive relative to the waving of compaction angle. Greater rigidity helps stabilize the change of the compaction angles.
