The common method of LiDAR classifications is Markov random fields (MRF). Based on construction of MRF energy function, spectral and directional features are extracted for on-board urban point clouds....
Measuring the Quality of Place (QOP) is a hard task since it involves both physical and socio-economic dimensions. Being one of the major land use categories, urban vegetation plays a significant role...
This paper investigates the relationship between the surface urban heat islands (SUHI) and the percent impervious surface area (%ISA) in Shanghai, China. The %ISA was characterized from a Landsat-7 ET...
Recently, it is required to investigate the spatial distribution of vegetation in urban areas on a regional scale for not only the improvement of urban environment but also the conservation of ecosyst...
Various methods of analysis and dataset have been used for urban studies. However, used urban data often has low spatial resolution,especially regional statistics, though statistical data can cover la...
This paper deals with the use of advanced GIS techniques for the study of modern and contemporary cities. A methodology for the selection, computerization, integration, and management of archive sourc...
Synthetic aperture radar interferometry (InSAR) has been an established method for long term large area monitoring. Since the launch of meter-resolution spaceborne SAR sensors, the InSAR community has...
Digital spatial data are underlying strong temporal changes. The typical approach of updating these changes is to check the data manually by superimposing them on up-to-date orthoimages from aerial or...
The city of Calgary, Alberta is the fastest growing major metropolitan area in Canada. Figures from the latest (2001) census indicate that the city has close to one million inhabitants. There are many...
Patterns of urban development across the United States are changing natural landscapes and their dynamics. Although scholars in landscape ecology are increasingly studying the relationship between urb...
Within the paper the applicability of SAR imagery for 3D reconstruction of urban areas will be discussed. Since data collection for this purpose is usually based on stereo imagery or dense point clo...
Very high resolution (VHR) DSMs (digital surface models) derived from stereo- or multi-stereo images from current VHR satellites like WorldView-2 or Pléiades can be produced up to the ground sampling ...
In this paper, we explore a method to collect spatial data and attribute data for urban geographic information system, including the set of data classification and coding standard adapted to all use...
