At present, massive amounts of data are distributed across different institutions, departments and scientific research institutes, and even at one site can be stored in heterogeneous storage systems. Therefore, it is hard to get the desired information from the massive data resource, which leads to the requirement of data sharing. In an effort to solve this problem, this paper studies Grid technology...
The paddy rice is one of the major crops in China and its planting areas increase year by year in Northeast China. In this study, a crop identification system in large scale based on two- phase classification using Remote Sensing (RS) is designed to do the rice identification. It includes the stratified sampling method to select the sample area using RS, and different spatial resolution RS images...
In this paper the adaptive feature selection model (AFSM) which is based on two layers, adaptive and multi-classes JM distance is studied. During the process of crop identification using remote sensing (RS) image classification, it is the effective way to improve the classification accuracy that the feature is proper treated. Firstly, with MODIS data as examples, the extracted spectral characteristics...
Vehicle-based estimation system on large scale crop acreage, which was equipped with GPS receivers, GIS software and a video camera on a off-road vehicle, can capture the images of video and calculate the crop acreage proportion based on matching between GPS information and image recognition. The system provides the credible data for government to make decision and provides technological method. In...
