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...
This study compares six change detection techniques to study land cover change associated with tropical forest (El Rawashda forest reserve, Gedaref State, Sudan). For this site, Landsat 7 Enhanced Thematic Mapper (ETM+) data acquired on March 22, 2003 and Aster data acquired on February 26, 2006 were used. The change detection techniques employed in this study were Post-Classification Comparison (PCC),...
It is well known that land cover change has important implication on urban planning, urban environment evaluation and so on. However, urban land cover information is not easy to be extracted because of its inner complexity resulting from human impact. Under this circumstance, the accurate recognition and classification of different land use types on urban area from remote sensing data has become an...
An accurate, up-to-date and spatially-explicate national land cover database is required for monitoring the status and trends of the nationpsilas terrestrial ecosystem, and for managing and conserving land resources at the national scale. With all the challenges and resources required to develop such a database, an innovative and scientifically sound planning must be in place and a partnership be...
