Aarhus Workbench & Aarhus SPIA

Aarhus SPIA  is a processing and inversion software for ground-based TEM and DC data. The graphical user interface simplifies the processing and inversion process and enables user-friendly and intuitive access to each step in the process. The processed data and inversion models are all saved in the same SPIA database and can be imported directly into the Aarhus Workbench Essentials module for easy visualization of the results. In Aarhus SPIA TEM, data obtained with ABEM WalkTEM is imported directly. The electromagnetic data can be plotted in different ways, eg raw or stacked in either dB/dt or apparent resistivity mode. Noise and spike filtering are done automatically when importing data.  The Aarhus SPIA DC module  imports  ABEM SAS instrument file formats  directly but data can also be imported either by importing other data files or by manually typing data into the software. On import, UTM coordinates can be added to each sounding.
