Development and implementation of software to obtain the Resistivity Depth Image (RDI) using TEM data.

This paper aims to show and validate the result of synthetic data processed by the ImagEM software. This program is been developed by the Electromagnetic Interpretation Research Group of University of Brasilia. It processes time domain electromagnetic data for different platform systems like in loop. The program uses a simplified inversion by the secant method. This method has proven reliable for a qualitative analysis and it has proven very agile in its processing. It is based on the analysis of the secondary magnetic field to obtain as result an estimated of the depth of the conductivity target, its shape in two dimensions beyond of the conductivity relative values. So the ImagEM shows the Resistivity Depth Image (RDI). This software was initially developed in MatLab and its final version will be in JAVA so it can be used on Windows and Linux.
