SummaryOur project entitled” Monitoring snow and ice on the power transmissioncorridors in alpine area” is supported by the National Natural ScienceFoundation of China (NSFC). We propose a research plan to revolutionize ourability to monitor the safety of the power transmission corridors. Specificobjectives of the proposed activity include: 1)an initial assessment of TERRASAR-X data acquired by the staring spotlight mode forconventional Interferometric Synthetic Aperture Radar (InSAR) analysis aimed atthe mapping of the snow and ice on the power transmission corridors in highalpine areas;2) propose an analytical model that accounts for snow or ice atthe power transmission corridor regions including transmission towers andtransmission lines;3) assess the information of snow and ice coverage on thepower transmission corridors so that their safety can be more effectivelymanaged. The long term continuous monitoring techniques include thesatellite-based InSAR measurements from the TERRASAR-X satellite and the ground station monitoring.The expected impacts of the project, to be finalized with the preparation ofapplication demonstration examples and the publication of results, include thedemonstration and assessment of TERRASAR-X data for snow and ice coverage measurement onthe power transmission corridors in alpine areas. The data obtained from TERRASAR-X is crucial for success of this project. We arewriting this proposal to acquire new TERRASAR-X SAR data for the research. We would like toobtain the TERRASAR-X data acquired by staring spotlight mode from Januaryto July, covering2.5 km x 6 km area in Liangshan Yi Autonomous Prefecture,Sichuan, China.
