This paper focuses on the detection of land cover change in Beijing using TM data collected on 22 May, 2002 and 20 May, 2010 respectively. For detailed analyzing the land cover change in different parts of Beijing, the central Beijing enclosed by fifth ring road was divided into 4 areas based on the ring roads. After image registration, mask and image clip, sample data of land cover types as water...
Postclassification comparison (PCC) and change vector analysis (CVA) have been widely used for land use/cover change detection using remotely sensed data. However, PCC suffers from error cumulation stemmed from an individual image classification error, while a strict requirement of radiometric consistency in remotely sensed data is a bottleneck of CVA. This letter proposes a new method named CVA in...
For a long time, global environmental change has become a focus all over the world. Environmental change not only alters the local natural landscape, but also will long impact the local or even large-scale ecosystem. While, the primary manifestation of environmental change is the land use/land cover change. In this study, taking Mentougou district in the west of Beijing for example, the temporal and...
In order to evaluate the impact of urbanization on carbon cycle, we selected the Beijing city as the study area to estimate CO2 emission both from anthropogenic activity and natural processes. The spatial pattern of annual CO2 emission in 1992 and 2005 in Beijing city was estimated by using the socio-economic statistical data, remote sensing data and GIS-based approach. The main factors include transport,...
