uasi - 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 کاملLaser Airborne Depth Sounder (lads):
LADS (Laser Airborne Depth Sounding) is a new laser bathymetric survey tool that has applicability in clear coastal (Case II) waters down to -70 m depth. The new sounding technique features rapid acquisition of large high-quality data sets via variable swath widths that are independent of water depth. This advanced airborne laser bathymetric (ALB) system was deployed along the southeast Florida...
متن کاملA25 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 کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
15 صفحه اولConductivity-depth imaging of time-domain EM data based on pseudo-layer half-space model
A conductivity depth imaging (CDI) algorithm for concentric-coil helicopter time-domain electromagnetic (HTEM) systems is developed based on the pseudo-layer half-space model. The primary advantages of this model are immunity to altimeter errors, and a bias towards conductive layers. Effective depth is derived empirically from the computed conductivity, sampling time, and apparent thickness of ...
