The remote sensing image fusion technique has been developed quickly and applied, which is an important remote sensing research topic. How to choose the right fusion method is one of the challenges that the field face. PCA, Brovey, IHS and Multiplicative are used to fuse QuickBird and SPOT5 low-resolution multispectral and high-resolution panchromatic images. The fused images are analysed and evaluated...
To help users find optimal rescue and evacuation routes, this approach uses the extended hierarchical node relation model (EHI-NRM) to represent a building's internal structure. The approach also employs the improved cellular-automata model (ICA) to consider route-choice behavior, such as spatial reasoning and communication among evacuees.
Desertification is one of the most serious environmental, social and economic problems in the contemporary world including China that has aroused close concerns of many countries' governments, and China as well. The paper summarized the current status, distribution, dynamic evolvement by remote sensing as monitoring method assisted with field investigation, and forecast the development trend of desertification...
