This paper focuses on evaluating the ability and contribution of using backscatter intensity, texture, coherence, and color features extracted from Sentinel-1A data for urban land cover classification and comparing different multi-sensor land cover mapping methods to improve classification accuracy. Both Landsat-8 OLI and Hyperion images were also acquired, in combination with Sentinel-1A data,...

We envision participatory texture documentation (PTD) as a process in which a group of users (dedicated individuals and/or general public) with cameraequipped mobile phones participate in collaborative collection of urban texture information. PTD enables inexpensive, scalable and high quality urban texture documentation. We propose to implement PTD in two steps. At the first step, termed viewpo...

Typology solution in architecture science seeks classifying constructions and spaces in terms of join features. Typology studies can be infrastructure of design in micro and minor levels. Therefore being oblivious of it in architecture and city planning can lead to state of chaos in urban aspect and makes heterogeneous urban textures. Current paper seeks to find factors influencing on formation...

Building extraction from remote sensing images is very important in many fields, such as urban planning, land use investigation, damage assessment, and so on. In polarimetric synthetic aperture radar (PolSAR) imagery, the buildings not only have typical polarimetric features but also have rich texture features. In this paper, the texture information is introduced to improve the accuracy of urba...

High resolution IKONOS stereo imagery provides an important data source for threedimensional scene extraction. In urban areas, it has been long a challenge topic to automatically extract urban objects from images due to the high object density and scene complexity. In this paper, we propose a new method for automatic 3d building reconstruction from IKONOS stereo images. Our approach is based on...

Virtual reality applications in the context of urban planning presume the acquisition of 3D urban models. Photo realism can only be achieved, if the geometry of buildings is represented by a detailed and accurate CAD model and if artificial texture or real world imagery is additionally mapped to the faces and roofs of the buildings. In the approach presented in this paper height data provided b...

This paper presents a new method for unsupervised urban area extraction from SAR imagery. The image segmentation method combines variogram texture feature extraction with OTSU threshold segmentation method, to obtain the result as good as traditional classical algorithm and have much higher computational efficiency. TerraSAR-X image is used to validate the proposed method, and experimental resu...

in the late decades of the 20th century, urban planners, due to the environmental worries arising from modernist urbanism looked for paradigms of new sustainable development regarding ideal city forms, since urban sprawl and horizontal expanse of cities lead to different socio–economic and structural disorders; therefore , during the recent decades , planners who are unanimously heading for sus...
