Interferometric Synthetic Aperture Radar (InSAR) can be used to monitor ground deformation at high spatial resolution. When integrated with Global Positioning Systems (GPS) so that atmospheric disturbance in InSAR result can be corrected, deformation can be resolved at sub-centimetre accuracy. The corrected InSAR result can be exported as a data layer into Geographic Information Systems (GIS) for further analysis. In collaboration with Hong Kong Polytechnic University researchers, the integrated InSAR-GPS-GIS system will be tested in both Hong Kong and Australia. The expected outcomes include a suite of algorithms and software tools capable of operational, cost-effective ground deformation monitoring.

干涉合成孔径雷达（干涉合成孔径雷达）可以用于高空间分辨率的地表形变监测。当与全球定位系统（GPS）结合使用时，干涉合成孔径雷达结果中的大气干扰可以得到校正，变形可以以亚厘米的精度得到解决。校正后的干涉合成孔径雷达结果可以作为数据层导出到地理信息系统（GIS）中，以供进一步分析。香港理工大学的研究人员将与该系统合作，在香港和澳大利亚测试InSAR-GPS-GIS系统。预期成果包括一套算法和软件工具，能够进行具有成本效益的地面变形监测。
