T1  - Modeling of Buildings and Roads for Urban Applications based on 2D Digital Maps
N2  - Three-dimensional models of urban objects play an important role in the urban applications such as urban planning, environmental concerning, or urban disaster mitigations. While the modeling of urban objects is time consuming and storage costing. This paper presents solutions for this. Buildings with regular shapes and plane roofs are constructed into computer models by identifying of graphic elements from the digital maps of urban area to get building base plane and building heights. Buildings with irregular shapes and non-plane roofs are constructed into computer models by employment of a specific system developed by the authors. Road objects and topologies are constructed into computer models by employment of specific algorithms. The solutions presented in this paper has been used in the development of urban disaster mitigation system for Shantou, China.

T1  - Real time geotechnical field data acquistion using a distributed approach
N2  - A distributed geotechnical remote analysis of data system (Distributed G-RAD) can benefit both owners and contractors in providing better quality control and assurance on geotechnical projects. The Distributed G-RAD approach involves efficient data acquisition using PDAs with GPS capability, radio frequency identification (RFID) tags for labeling soil samples, laser scanning for measuring lift thickness and volumes of stockpiles and borrow pits. Spatial data storage is provided using a geographic information system (GIS). Portions of this system are already developed while other parts are still being considered. This paper also describes how RFID and laser scanning technologies can be used in the larger Distributed G-RAD system.
