报告摘要：
Recent technological advancement has enabled acquisition of remote sensing data at increasingly high spatial resolution. HD camera from space routinely generates up to hundreds of terabytes per hour. This pushes research for high performance algorithms. While conventional multi-spectral sensors have improved their spatial resolution, new emerging applications require high spectral content. Hyperspectral imaging is a technology to mimic spectroscopy for target identification. It is rich in spectral information with hundreds of bands. There is still no operational spaceborne hyperspectral mission with global coverage. However, this is going to change in the next 2 decades with several national and international efforts to launch new hyperspectral satellite. One disadvantage of the future hyperspectral missions is that most will opt for a 30m resolution which is too coarse for many applications. Spatial enhancement with superresolution reconstruction, pansharpening and image fusion is one of the hottest topics. Synthetic hyperspectral data, hundreds in dimension at high spatial resolution and possibly high revisiting temporal resolution, has high potential to materialize as a standard product. This short talk will brief the recent development in remote sensing, in particular future spaceborne hyperspectral missions and the pressing needs for powerful algorithms for big data handling and enhancement, the opportunities and challenges.
