PROBA（Project for On-Board Autonomy）小卫星是欧空局于2001年发射的一颗最小的对地观测卫星，CHRIS（Compact High Resolution Imaging Spectrometer）是搭载在PROBA平台上最主要的成像光谱分光计，具有五个成像模式，以其卓越的光谱空间分辨率及多角度的优势为不同的研究目的分别对陆地、海洋及内陆水体进行成像。它是目前世界上唯一可以同时获取高光谱和多角度数据的星载传感器，空间分辨率高，光谱范围宽，在生物物理、生物化学等方面能收集到丰富的信息。黑河流域目前共有PROBA CHRIS数据23景。\n

Proba (project for on board autonomy) small satellite is the smallest earth observation satellite launched by ESA in 2001. Chris (compact high resolution imaging spectrometer) is the main imaging spectral spectrometer mounted on proba platform, with five imaging modes, With its excellent spectral spatial resolution and multi angle advantages, it can image land, ocean and inland water respectively for different research purposes. It is the only spaceborne sensor in the world that can obtain hyperspectral and multi angle data at the same time. It has high spatial resolution, wide spectral range and can collect rich information in biophysics, biochemistry and so on. At present, there are 23 scenes of proba Chris data in Heihe River Basin.\n
