With the development of remote sensing techniques, RS had become an effective way to do the disaster monitoring and assessment. Nowadays, remote sensing plays an important role in disaster mitigation. But the methods to produce the main product of remote sensing data - image maps, are very complicated, and varies work flows, lot of image processing and operations are included. The requirement for...
Nowadays natural disasters especial earthquakes frequently occur all over the world. Thus rapid mapping of remote sensing system has practical significance. In this paper, based on the methods of disastrous expression of multi-scale geographic maps and remote sensing images, processes of fast mapping were proposed and researched. It includes quick match of base map database and disastrous thematic...
With Huabei Plain of China as the study area, this research proposed a new method for pixel-level MCI (multiple cropping index) extraction with multi-temporal MODIS EVI data based on crop phenology and DT (decision tree). The method could be divided into two steps. First, based on the local crop phenology, several features were identified to discriminate pixel-level MCI, which includes three types:...
