Urban vegetations have infinite proven benefits for urban inhabitants including providing shade, improving air quality, and enhancing the look and feel of communities. But creating a complete inventory is a time consuming and resource intensive process. The extraction of urban vegetation is a challenging task, especially to monitor the urban tree heights. In this study we present an efficient e...

Urban sustainable development strategies are of great importance to rapidly urbanized countries such as China. One of the most challenging problems is how to coordinate urban spatial development with social efficiency and environmental protection, e.g., highly efficient low-carbon urban traffic. Despite broad research efforts with respect to the influence of urban form on travel patterns, quest...

The aim of this paper is investigate the social sustainability of the bazaar according to viewpoint of citizens as the main owners. What factors are the main reasons for back to this place in the image of people. Bazaar is not only a shopping center like modern commercial center in the city, but as one of the oldest urban spaces which is also active today, has an important role in shaping urban...

The paper explores a framework combining remote sensing and spatial metrics aimed at improving the analysis and modeling of urban growth and land use change. While remote sensing data have been used in urban modeling and analysis for some time, the proposed combination of remote sensing and spatial metrics for that purpose is quite novel. Starting with a review of recent developments in each of...

Rapidly growing urban areas tend to reveal distinctive spatial and temporal variations of land use/land cover in a locally urbanized environment. In this article, the author analyzes urban growth phenomena at a local scale by employing Geographic Information Systems, remotely sensed image data from 1984, 1994, and 2004, and landscape shape index. Since spatial patterns of land use/land cover ch...

The Fourier transform and spectral analysis are employed to estimate the fractal dimension and explore the fractal parameter relations of urban growth and form using mathematical experiments and empirical analyses. Based on the models of urban density, two kinds of fractal dimensions of urban form can be evaluated with the scaling relations between the wave number and the spectral density. One ...

Land surface temperature (LST) is an important parameter to study in urban climate. The understanding of the influence of biophysical factors could improve the establishment of modeling urban thermal landscape. It is well established that climate hold a great influence on the urban landscape. However, it has been recognize that climate has a low priority in urban planning process, due to the co...

The Urban Surveillance Systems generate huge amount of video and image data and impose high pressure onto the recording disks. It is obvious that the research of video is a key point of big data research areas. Since videos are composed of images, the degree and efficiency of image compression are of great importance. Although the DCT based JPEG standard are widely used, it encounters insurmoun...

Within the paper the integration of 3D building models in the context of location aware services is presented by two exemplary applications. First the intuitive access to object related information within an urban environment is by telepointing is described. For that purpose terrestrial images are mapped against a 3D model of the environment based on direct georeferencing and a image based loca...
