Gplivemodel
gplivemodel computes dispersion curves, autocorrelation curves, ellipticity curves or SH tranfert functions from a layered model. Compared to command line tools like gpdc, gpspac, gpell and gpsh, ground models can be interactively modified in a graphical user interface.
Important: this is not an inversion tool. Manually inverting a dispersion curve with this tool leads to an extremely poor and biased estimation of the global solution of the inversion problem. dinver is a much more appropriate inversion tool.
Description
gplivemodel graphical interface is structured in 3 panes:
- Plots of Vp and Vs profiles, and the computed curve (top of figure)
- Model definition (bottom left of figure)
- Background models
- Reference model
- Foreground model
- Control panel (bottom right of figure)
Background models and Reference model are free text editors containing layered model descriptions. Model format is the same as for gpdc, gpspac, gpell or gpsh. Control panel has a collection of sliders to control the transformation of Reference models into Foreground models. A right-click on a slider lets the user editing the effects.
Above plots (included in a graphic sheet) are continuously updated after any modification of Background models, Reference models editors or Control panel. Any number of model descriptions can be entered there. By default, axis limits are also changed. To preserve their current state, menu Format has option Automatic limits to be checked or not.
Attributes (color, symbols,...) of velocity profiles and computed curves can be set be editing the legends located on the left of the curve plot.
