Northeast China, the most important region for commercial grain farming in China, is vulnerable to drought due to high fluctuation in monthly rainfall. Timely, accurate and effective drought monitoring is very essential for securing the output of grain farming. In this study, three widely used drought indices were compared using satellite soil moisture data and their capability for drought monitoring...
Northeast China, one of the most important grain producing regions in China, is vulnerable to drought. Timely, accurate and effective drought monitoring in the region is very essential to secure its output grain production. In this paper, the temporal and spatial distribution of drought in Northeast China was analyzed based on the TVDI. Also the drought change trend from 2001–2013 in Northeast China...
Current remote sensing sensors can only provide data either with high spatial resolution or with high temporal resolutions. It's a challenge to fully characterize the patchy phenology change in the dryland region. The Flexible Spatiotemporal Data Fusion (FSDAF) method, can produce synthesized frequent high spatial resolution images through blending Landsat 30 m data with MODIS 500 m data to produce...
Change detection is still a research hotspot in digital image processing and information extracting area, but how to detect the changes of target area quickly and accurately is still a challenge. This paper proposed a change detection method which find the target areas first and then locate the change types. An improved fuzzy c-means (FCM) algorithm was put forwarded and proved to be sensitive to...
