فضاهای شهری با روندی ناموزون و ناهماهنگ با ویژگیهای اجتماعی و فرهنگی جامعه و نیز خواسته ها و نیازهای شهروندان در حال رشد و گسترش هستند که این فرایند ضمن مخدوش نمودن سیما و هویت شهرها سبب ظهور بسیاری از مشکلات اجتماعی و فرهنگی گردیده است و نارضایتی ساکنان شهرها، عدم احساس تعلق آنها به سکونتگاهایشان و در نتیجه عدم احساس مسئولیت در حفظ و ارتقاء آن، افزایش جرائم شهری و نیز عدم احساس امنیت از حضور د...

human presence and accordingly establishing suitable condition for social interactions are important factors in shaping urban spaces. caring to different aspects of improving environmental qualities especially perception aspect and ease of perception from the environment with legibility improvement is an element that was emphasized from the base of urban design. the role of time, commence of da...

in traditional bazaars social interactions, parallel to economic and movement interactions, created a mixed urban space which was dynamic, lively and attractive to the audience. however, modern shopping centers and shopping malls are economy focused and void of variety of urban spaces like traditional bazaars. the presence of public open spaces and urban squares undetectable from traditional ba...

urban design, being concerned with the quality of built environment, requires close interaction with other disciplines such as urban planning, environmental design and architecture as well as sociology, psychology, and economics. this is necessary in order to appropriately recognize and analyze different dimensions of existing problems and provide solutions to them and to improve the quality of...

Conventional two dimensional(2D) maps and DTMs are insufficient to represent geographic information in urban space comprising high-rise buildings and underground structures. There is a pressing need for a model of three dimensional(3D) representation of urban space, that is, a Digital Urban Space Model(DUSM). However, existing solid modelling techniques cannot be directly applied to the 3D repr...

Although many methods of spatial analysis have been developed for a better understanding and modelling of urban space analysis, there is still a need for exploration of new analytical techniques for modelling urban spaces. Space Syntax models the spatial configurations of urban spaces by using a connectivity graph representation. Such a configuration of space identifies patterns that can be use...

Urban fabric characterization is very useful in urban design, planning, modeling and simulation. It is traditionally considered as a descriptive task mainly based on visual inspection of urban plans. Cartographic databases and geographic information systems (GIS) capabilities make possible the analytical formalization of this issue. This paper proposes a renewed approach to characterize urban f...

Assessment of landscape change is critical for attainment of regional sustainability goals. Urban growth assessments are needed because over half the global population now lives in cities, which impact biodiversity, ecosystem structure and ecological processes. Open space protection is needed to preserve these attributes, and provide the resources humans need. The San Francisco Bay Area, Califo...

Greenhouse gas emission of carbon dioxide (CO2) is one of the major factors causing global climate change. Urban green space plays a key role in regulating the global carbon cycle and reducing atmospheric CO2. Quantifying the carbon stock, distribution and change of urban green space is vital to understanding the role of urban green space in the urban environment. Remote sensing is a valuable a...
