|Title||Monitoring human-induced surface deformation with TerraSAR-X data stacks|
|Investigator||Liao, Mingsheng - Wuhan University, LIESMARS|
Three AOIs have been selected for the proposed study in the Los Angeles Basin, including two oil fields in Santa Fe Springs and Orange County as well as the Santa Ana aquifers in Pomona. From the available GPS data, we know that there is a distinctive seasonal deformation in the study areas. Therefore, we need to model the periodical deformation function in the PS-InSAR processing to get more precise deformation estimations.
A similar strategy can be used for Taiyuan. There are three minor differences. First, the available Taiyuan data stack is much larger. Second, another external data (leveling data) other than GPS will be available for result validation. Third, the available ENVISAT ASAR PS-InSAR results cover a long time span, which can help us to derive the relationship between time and deformation in case of limited GPS/leveling measurements.
In general, five main steps should be carried out:
The project is funded by the National Key Basic Research Program of China (Grant No. 2013CB733205) and the National Natural Science Foundation of China (Grant No. 41174120, 41271457 and 41021061).
