Traditional techniques in building science portals and gateways are being challenged by new techniques such as Web 2.0 and Cloud Computing. This paper discusses some of our efforts to evaluate these techniques as we evolve the QuakeSim architecture. We believe that architecturally both traditional and newer approaches for Gateways are very similar, thus giving us a path for moving to hybrid app...

environmental characteristics, including the quality of green spaces, constitute one of the determinants of buildings (house & apartment) transaction prices. in this research, impact of urban green space on building's transaction prices (rials/m2) in karaj region, district 1 (jahanshahr), was analyzed. therefore, a questionnaire concerning building characteristics and transaction prices wa...

The article presents a novel approach for the automatic generalisation of 3D building models with regard to the cartographic visualisation of urban landscapes. Building objects are geometrically simplified for the purpose of levels of detail generation to speed up rendering and to improve the perceptibility on small displays commonly found in mobile devices. Generalisation is realised in a proc...
