Session 3.2 GNGTS 2024 QGIS Widget Locatng the data and checking the acquisiton surroundings during processing is essental to ensure a good quality analysis. Choosing QGIS as the base of EEMstudio means embedding a powerful Geographic Informaton System (GIS), the most widespread sofware available with this purpose, to the processing and modelling tools. This results in having just one workspace to work with and the possibility to use data fles among other georeferenced layers. EEMstudio plugin starts as a docked widget in the QGIS main window (Fig. 1). Here there is the possibility to organize data and modelling fles, and open them for processing or visualizaton of the results, loading automatcally the acquisiton points. Fig. 1 – QGIS main window with EEMstudio widget on the right, used for management of processing and modelling fles. Once uploaded, the coordinates of the acquisiton points are automatcally added to the QGIS layer, among eventual other layers in the QGIS project. In this fgure, two types of data are shown: galvanic and inductve (airborne). White dots are the electrodes, red circles and blue points are the positons of the quadrupoles used in the soundings selected in the galvanic processing app (Figure 2a). Black dots are the inductve soundings and yellow points are the soundings highlighted in red in the inductve processing app (Figure 2b). Processing A separate window is dedicated to data processing and visualizaton of forward and model. Regarding processing, this graphic interface allows to select data to refne the dataset, to clean it from coupling efects and noise, using a vast range of shortcuts to optmize the process. Moreover, all the soundings that are shown and selected in this window are also ploted as georeferenced points in the QGIS map, to locate them instantly.
