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...

Research into urban geomorphology is relatively recent (Brown et al., 2017; Rosenbaum 2003; Zwolinski 2017), and the discipline gaining interest at an accelerating pace, as globa...

in developing and newly industrialized countries, population growth and migration contribute immensely to the development of megacities and mega urban areas. in most cases, the rapid development ofcities has far-reaching consequences for the ecosystem in general and the hydrological cycle in particular. the developments in china within the last decades show an interesting, but complex setting. ...

Urban represents one of the most dynamic areas in the global change context. To support rational policies for sustainable urban development, remote sensing technologies such as Synthetic Aperture Radar (SAR) enjoy increasing popularity for collecting up-to-date and reliable information such as urban land cover/land-use. With the launch of advanced spaceborne SAR sensors such as RADARSAT-2, mult...

In this chapter, the main idea about a design tool and its object database system will be described. The design tool should improve design practice with respect to analysis and improving existing and planned urban environments. Preconditions for defining the design tool’s purpose are the determination of the “well-situated” urban elements, their impact on cognitive mapping, and the exploitation...

The visible landscape is believed to affect human beings in many ways, including aesthetic appreciation and health and well-being. The aim of this paper is to analyse the range of landscapes used in environmental psychology studies, and the evidence of health effects related to viewing these landscapes. A literature review of publications linking landscapes and health effects was conducted. Thi...

Detailed land cover information is valuable for mapping complex urban environments. Recent enhancements to satellite sensor technology promise fit-for-purpose data, particularly when processed using contemporary classification approaches. We evaluate this promise by comparing the influence of spatial resolution, spectral band set and classification approach for mapping detailed urban land cover...

Land cover mapping of the urban environment by means of remote sensing remains a distinct challenge due to the strong spectral heterogeneity and geometric complexity of urban scenes. Airborne imaging spectroscopy and laser altimetry have each made remarkable contributions to urban mapping but synergistic use of these relatively recent data sources in an urban context is still largely underexplo...

Although spectral mixture analysis has been widely used for mapping the abundances of physical components of urban surface with moderate spatial resolution satellite imagery recently, the spectral heterogeneity of urban land surface has still posed a great challenge to accurately estimate fractions of surface materials within a pixel. How to dealing with the highly spectral heterogeneous nature...

Accurately quantifying the variation of urban green space is the prerequisite for fully understanding its ecosystem services. However, knowledge about the spatiotemporal dynamics of urban green space is still insufficient due to multiple challenges that remain in mapping green spaces within heterogeneous urban environments. This paper uses the city of Hangzhou to demonstrate an analysis methodo...
