Abstract:In order to efficiently extract quantitative parameters in active tectonics research, JX4C digital photogrammetric system has been used to found stereo model based on CORONA KH-4B stereo pairs with 2 m resolution, which were declassified in 1995 by USA for scientific purpose. Meanwhile, large scale digital elevation model (DEM) and digital orthophoto mapping (DOM) have been formed. These processing techniques are applied in a ease study of the Kuqa fold-and-thrust belt in southern Tianshan, China, to quantitatively analyze the Kumugeliemu active fault and the Qiulitage active fault-related folds, considering the seismic reflection profiles therein and data from field measurements. Results show that the CORONA stereo pairs can be used in JX4C digital photogrammetric system, and root mean square error (RMS) of relative orientation is about 0.01 mm,while absolute orientation is about 10 m. Some parameters for deformation of river terrace and fault and fold scarps are identi fied and measured, which are helpful to reveal the characters of active tectonics. The processing techniques are feasible and ef fective particularly in remote settings with complex topology and the measurement precision can meet the requirement for analysis of active tectonics.
