A25 Delaunay Triangulation-based Spatially Constrained Inversion for Quasi 3d Modeling of Airborne Tem Data
SUMMARY The spatially constrained inversion (SCI) is a robust methodology for quasi-3D modeling of geoelectrical and EM data of varying spatial density, using a 1D forward solution. Information migrate horizontally through spatial constraints applied between nearest neighboring soundings, and allow resolution of layers that would be locally poorly resolved. The constraints are built using the D...
متن کاملuasi - 3 D modeling of airborne TEM data
We present a new methodology, spatially constrained inversion SCI , that produces quasi-3D conductivity modeling of electromagnetic EM data using a 1D forward solution. Spatial constraints are set between the model parameters of nearest neighboring soundings. Data sets, models, and spatial constraints are inverted as one system. The constraints are built using Delaunay triangulation, which ensu...
متن کاملConstrained inversion of P-S seismic data
A method to estimate S-wave interval velocity, using P-S seismic data is presented. The method is composed of three steps. First, the P-S data are converted to a relative change in S-velocity section. The section is then linearized. Constrained inversion is used to convert this last section to S-interval velocity. To illustrate the method, the S velocity of a field data set was derived, and a V...
متن کاملholistic approach to inversion of frequency - domain airborne EM data
We have developed a holistic method for simultaneously calibrating, processing, and inverting frequency-domain airborne electromagnetic data. A spline-based, 3D, layered conductivity model covering the complete survey area was recovered through inversion of the entire raw airborne data set and available independent conductivity and interface-depth data. The holistic inversion formulation includ...
متن کاملThe 3D inversion of airborne gamma-ray spectrometric data
Gamma radiation measurements are made at airborne survey heights and, through suitable processing, are converted to estimates of the count rates due to the radioelements (K, U and Th) at each observation point along the flight lines. The conventional processing of these data would include a correction for deviations in the aircraft height from the nominal survey height. The elemental count rate...
