The paper realizes water body extraction well using object-oriented classification method based on SPOT5 image. Firstly, segment image according to multi-scale image segmentation method based on edge-detection algorithm. Secondly, determine various characteristic parameters in land surface features according to object characteristics such as spectrum, shape and texture. And thirdly, use SVM (Support...
High-resolution remote sensing images with a clear spatial and texture information are increasingly used for land use information extraction. Traditional pixel-based remote sensing classification methods are unable to meet the high-precision requirements of land use classification. GIS technology has brought innovations in computer graphics technology. Digital land use maps are widely used in land...
It's necessary to discuss the topology model of digital images for integrating remote sensing and geographic information system in higher levels. Based on cellular complex theories, a hierarchical image representation is presented that maintains both raster and vector representations of an object inside a same data structure and to translate between spatial concepts in image understanding and mining...
Urban form reflects cultural, socio-economical and environmental parameters and constraints. An important environmental generator of urban form is climate. The majority of existing research that deals with the influence of climate on the development of urban form tends to present vernacular (traditional) urban form as a successful combination of architecture, urban design and climate. This assumption...
