EEMstudio: Process and Model Electric and Electromagnetic Data with a QGIS Plugin
N.A.L. Sullivan, Andrea Viezzoli, Gianluca Fiandaca · 2024
Summary EEMstudio is a QGIS plugin for visualization and processing of inductive and galvanic data in a GIS environment, as well as a graphical user interface for data modelling and inversion through the inversion kernel EEMverter, all in one unique environment. EEMstudio allows visual inspection of data and manual culling of outliers using an ad-hoc interface, as well as to run inversions and to evaluate data fit and correspondence between data and inversion models, all synchronized with the QGIS georeferenced maps. The map from QGIS is integrated during the processing to monitor the position of the soundings/electrodes and target possible coupling occurrences. Processing is handled in an interface composed by many interactive plots where acquired data, forward data and models can be displayed and processed, synchronized with the map. Lastly, the modelling apps facilitate the set-up of inversion and the construction of synthetic models to use as starting models or for forward computation. EEMstudio is distributed freeware and open source, and the inversion kernel EEMverter is distributed freeware together with EEMstudio in its LITE version, which allows to run modelling of galvanic data with induced polarization and of ground-based inductive data.
