An object-oriented change detection algorithm was proposed and experimented to multi-temporal ALOS remotely sensed images. In contrast with conventional pixel-based algorithms, this approach processed homogenous blocks generated by object-oriented image segmentation for change detection. Similar pixels were merged into homogeneous objects by image segmentation at first, and each object (polygon...

Modeling and simulating the effects of human factors on landscape change remain as challenges for ecological studies. In this paper, we present a dynamic landscape simulation (DLS) approach to elucidate human-induced landscape changes for a 5104 km study area within the Chicago metropolitan region. The DLS consists of an urban growth simulation submodel and a land-cover simulation submodel. Thi...

Right to the city is composed of appropriation and participation in urban affairs. Appropriation is realized through movement in the city, presence in it, comfort feeling, and having proper spaces. While urban participation is possible through being involved in urban policy-making, decision-making for physical and spatial issues, urban economy, ownership and control of urban...

walking being the oldest form of urban transport, and until the advent of major transformationsin transport technology in the nineteenth century, most cities were structured in ways that supported walkability.today, there is a change in transportation which emphasizes, the traditional pedestrian paths which are increasinglybecoming non-regulated spaces when compared to the urban spaces for auto...

introduction “green infrastructure” is a term that describes the abundance and distribution of natural features providing ecological services necessary for community wellbeing specially in urban areas where these are limited. green infrastructure is increasingly espoused by landscape conservation and metropolitan planning because it is an effective way to surrogate ecological network functions ...

The main concept behind this paper is that pattern and processes are linked in a mutual way. In the last decades landscape ecology was dominated by quantitative descriptions (landscape metrics ) of the landscape under concern and its components. Now there is a growing interest in the cause-effect-relationships between these environmental characteristics. Highresolution aerial photography hold a...

tehran city has been subject of critical environmental challenges during the course of 20th. century namely: massive population growth, broad expansion, reduction in urban open/green spaces, increasing in energy consumption and waste production. releasing industrial wastewater into river valleys have led to considerable changes in structure of city's natural landscape. the natural structur...

The technology of computer vision and image processing is attracting more and more attentions in recent years, and has been applied in many research areas like remote sensing image analysis. Change detection with multi-temporal remote sensing images is very important for the dynamic analysis of landscape variations. The abundant spatial information offered by very high resolution (VHR) images m...
