Unified Data Format

On this page we like to provide a basis for exchange and comparison of data. First a common data format is proposed that can be used to compare synthetic and field data.

In order to have a common basis we like to present a data format for multielectrode data. The information about electrode positions is separated from logical use of electrodes and associated fields. This should go along with most measuring devices as well as forward calculation routines.

The unified data format description.

See the forum for discussing how this should develop.

Other useful ways for inputting data in form of collected profiles (.pro-File) or soundings (.s2d/.s3d-File), third party (Res2dInv) or device files (ABEM, Resecs, Geotom, ...) can be found in DC2dInvRes/Dc3dInvRes documentation under Menu->File->Open.

I'll provide Matlab-routines for reading and writing data soon.


Synthetic data

are useful for testing different codes (forward and inversion) against each other
the homogeneous flat halfspace is easily analytically available
simple 2d case with topography and uniform conductivity of 1 S/m
the 3d mound from our GJI inversion paper with 1 S/m (pure topography effect)
the complete synthetic model with 2 layers and a cavity
circle object (1m radius) with 1 S/m calculated after Weidelt & Weller

Field data

everyone is encouraged to send interesting field data
