A diagnostic analysis of the space–time structure of error in quantitative precipitation estimates (QPEs) from the precipitation radar (PR) on the Tropical Rainfall Measurement Mission (TRMM) satellite is presented here in preparation for the Integrated Precipitation and Hydrology Experiment (IPHEx) in 2014. IPHEx is the first NASA ground-validation field(More)
Multi-element scanning imaging spectrometer is a typical spectrometer with complex geometrical distortion, which falls in between optical mechanical scanning imaging and push broom imaging. Based on the field imaging spectrometer system (FISS) developed in China, a geometrical distortion model for multi-elements scanning imaging spectrometer is proposed.(More)
A method of spectral reconstruction based on FLAASH (Fast Line-of-sight Atmospheric Analysis of Spectral Hyper cubes) is introduced in this paper. A scene of Hyper ion image is adopted with hyper spectral data in October 14th, 2008 in the Mountainous regions of Guizhou. The FLAASH model is adopted spectral reconstruction five typical objects. Atmospheric(More)
Height accuracy is one of the most important requirements of stereo mapping. In order to improve the height accuracy of airborne photogrammetry, a new method using a multicamera system was developed. This method collects multiple groups of stereo images with 60% overlap between adjacent stations, and with 90% overlap between simultaneous images. In this(More)
