During the information detection and discrimination, the remote sensed data always represents three important characters: space character, spectral character and time character.

遥感数据源在信息提取和识别的过程中主要表现为三大特征：空间特征、光谱特征和时间特征。

Imaging spectrometer is a kind of space remote sensing detector. It can get space and spectral distribution information of a target at the same time.

成像光谱仪是一种空间遥感探测器，它可以同时获取目标的空间和光谱分布信息。

The stories come in order of composition, with dates, and in three sections, each of them flagged by a quietly resonant illustration (a view of the planet from outer space, a heavily restored classical fresco, a painting of a spectral cadaver).
