VSP data inversion for vertical velocity gradient and elliptical anisotropy model [PDF]

open access: yesE3S Web of Conferences, 2019
Inversion of velocity parameters for the walkaway VSP data in a multilayered medium can be impeded by velocity gradients and anisotropy in some layers. A problem occurs if we compare velocities obtained from borehole seismic profiling which are equal to ...

On the BIC for determining the number of control points in B-spline surface approximation in case of correlated observations

open access: yesJournal of Geodetic Science, 2020
B-spline curves are a linear combination of control points (CP) and B-spline basis functions. They satisfy the strong convex hull property and have a fine and local shape control as changing one CP affects the curve locally, whereas the total number of ...
