The SiTEM/Semdi program package is a powerful tool for processing and inversion of ground-based time-domain electromagnetic data (TEM). Over the last 10 years the software package has been used to process and invert more than 30 000 TEM-soundings in Denmark. SiTEM is the processing part of the program package.
The TEM processing is easily accessed via a graphical user interface (desktop example). Multiple data plots can be viewed at the same time to assist in the processing procedure. Bad data are removed directly in the data plot windows using the mouse. The data uncertainty can be determined either from noise measurements or directly from the data stack.
