Land cover and land use changes associated with urbanization are important drivers of local geological, hydrological, ecological, and climatic change. Quantification and monitoring of these changes in 100 global urban centres are part of the mission of the ASTER instrument on board the NASA Terra satellite, and comprise the fundamental research objective of the Urban Environmental Monitoring (U...
Historical urban textures remind the period of time that cities were constructed based on the requirements, purposes and tastes of residents. On the other word, the viewpoint of builders and residents were close together. But nowadays, without attention to the memories and fixation of citizens, rapid growth in historical urban textures leads to destruction of memories and perishing the iden...
Introduction: Natural disasters are known as one of the most important factors in the destruction of human settlements. One of the key concerns for urban planners is examining how natural disasters affect human settlements, particularly cities. Earthquake is one of these natural disasters that has always threatened human settlements and can cause a lot of damage and casualties in a short period...
Due to the inherent discrete nature of sensing, interpolation is a key activity in sensing. Interpolation in urban computing faces an unprecedented inference issue that was not present in large scale traditional sensing environments. Obstacles such as buildings and walls are prevalent in urban sensing, and it is important to consider them in urban sensing interpolation. This paper introduces an...
Aims & Backgrounds: Physical indicators of urban texture such as the age of buildings, microstructure, number of floors and type of building materials have a determinant role in the intensity and extent of the cities vulnerability in the face of earthquakes. Many Iranian cities are located on areas with moderate and high risk of earthquakes. Hence, Special attention to the elements qualities an...
Aims: Urban regeneration seeks to solve the problems of neighborhood erosion through the improvement of worn and damaged areas. In the meantime, stimulus projects and development of urban regeneration are productive in order to restore prosperity and development to the desired areas to launch a cycle of lively and dynamic activity in these areas. The purpose of this study was to provide a model...
Municipalities need accurate and updated inventories of urban vegetation in order to manage green resources and estimate the profit of urban forestry activities. Earlier studies using high resolution satellite images have shown that automatic tree detection in urban areas using traditional classification techniques remains a very difficult task. This is mainly due to intra-crown spectral variat...
Urban areas studies by means of C-band satellite SAR imagery has not provided relevant information while the use of InSAR has shown that it is possible to detect urban settlements with rather good accuracy. In this study we have analysed the potential benefits connected with the combination of four SAR and InSAR signatures (short and long term coherence, backscatter and intensity texture) for u...
