With the sustaining economic development in China, the timely, accurate and objective agricultural production information service has been highly demanded by the central and provincial governments. China Agricultural Remote Sensing Monitoring System (CHARMS) is an operational agricultural monitoring system in the Ministry of Agriculture of China to meet this demand.
China's rape acreage and total output of rapeseeds ranks among the top in the world, accounting for more than 30% of the world's total rape acreage and output of rapeseeds. This paper takes Landsat TM as the main data source in conducting the study of extracting rape acreage information in the Shou County, Anhui Province. Through analysis and calculations of phenological diversity, spectral discrimination,...
It is important for the improvement of numerical weather forecast accuracy to reseach the simulation error of rapid radiative transfer model. Using the radiosonde data as the input of rapid radiant transfer model CRTM, the simulation error of infrared channels observation of VIRR on FY-3A is analyzed. The distribution of model biases in radiance of three infrared channels are approximate normal ditribution,...
This paper has focused on a new automated detection and removal of cloud shadows of remotely sensed data to service quantitative interval of atmospheric parameters, using the FengYun-3 (FY-3), moderate spatial resolution and HuanJing-1 (HJ-1), high spatial resolution satellite data. Taking into account interaction between neighboring pixels in remote sensing images, this research aims at the special...
Based on a great deal of spectral data for different kinds of ground objects which were denoised by wavelet transform method, the spectral characteristics and changing rules of water, paddy field, wheat, cole and vegetable greenhouse in Chao Lake basin were analyzed with ASD portable spectrum analyzer by field investigation and plot survey. The spectral data of typical ground objects in Chao Lake...
This paper demonstrates the Ruddick's algorithm to utilize atmospheric correction with the hyper-spectral imagery over Chinese turbid lake water obtained by China first hyperspectral imager (HSI) onboard HJ-1A. The paper studies on the sensor characteristics and analyzes the optical properties of turbid lake water in Taihu Lake. Based on consideration about real circumstances, the paper recalibrates...
