The grounding line (GL) is the location where ice sheet lose contact with the bed rock. Since this line is under the surface ice, it's hard to define the GL. However, the different basal condition besides the GL caused different vertical movement and a flexure is often formed at the GL. This flexure is detectable by optical images. Meanwhile the ocean-induced vertical movement is detectable by repeat...
This paper focuses on a new approach for the calibration of IMU misalignment angles. Firstly the rigorous mathematic model of IMU misalignment describing the relationship among IMU output angles, misalignments and exterior orientation angular elements is discussed, then one-step and two-step these two fundamental calibration methods are introduced. According to the idea of two-step calibration a rigorous...
High altitude photographic work such as Aerial photogrammetry and UAV photography has very high demands on geometric optical parameters of the CCD camera, one millimeter or one pixel error of geometric optical parameters tends to cause a few meters or even dozens of meters error on the ground, so the camera's high-precision geometric optical parameters calibration is a crucial step for data geometry...
Suspended substance (SS) concentration is an important index of water quality evaluation. It is significant to build a quantitative remote sensing retrieval algorithm to inverse the SS concentration. With focus on the problems that empirical method is lack of the support of the physical theory and not robust in quantitative remote sensing monitor of SS concentration in inland water, the feasibility...
Monitoring seasonal changes in vegetation activity over wide areas is essential for many applications, Satellite remote sensing offers a systematic and objective means for detecting and monitoring ecological environment.A large amount of satellite remote sensing data at different spatial, spectral and temporal resolutions was proved to estimate Land cove change.One of the most widely used approaches...
