Explorer Window

| << | >> |

The Explorer Window is placed on the right side of the screen and provides easy access to the workspace environments of the program. The workspaces and their dependent menus are arranged in an intuitive tree with roots on the left and branches on the right. To move from one environment to the other select the appropriate item from the menu. When the Explorer Window is closed or hidden, it may be brought forward by selecting Explorer Window from the View menu or by clicking the button on the toolbar.

 

Items available in the Explorer Window are different depending on whether a Forward (Survey Design) or Inversion project is in session. Since the forward menu is less complicated, the inversion menu will be described. From the top to the bottom, we find the following items:

Schedule

For a Data Inversion Project:

  1. Import Syscal file provides access to a component for importing IRIS BIN files.
  2. Data set (file name): appears after a Schedule has been input. This branch provides direct access to the Data Quality Control Workspace for visualization of electrodes, quadrapoles and measurements, quality control operations, and generation of pseudo-plots of apparent resistivity and IP.
In Survey Design mode the Import Syscal file item is substituted by a Schedule Maker link to the Sequencer module.

Data Quality Control

Visualization of electrodes, quadrapoles and measurements, quality control operations, and generation of pseudo-plots of apparent resistivity and IP.

Mesh and Resistivity/IP Model

  1. Make Mesh: open the mesh workspace to generate or manipulate mesh settings using a menu (rather than directly entering the settings in the Configuration Settings).
  2. Make Resistivity/IP Model: open the Model Workspace to build a resistivity or IP model (assign background + insert anomalies). Anomalies are not usually inserted for an inversion, however an appropriate background should be assigned.  Anomalies are typically used for forward modeling.
  3. Export Mesh and Resistivity Model: export the generated mesh and resistivity model including the background region.
  4. Export Mesh and IP model: export the generated mesh and IP model including the background region.
  5. Import Mesh and Model: import a mesh and a resistivity model that has been saved using the export functions above.
  6. Load Resistivity Model: load the frameword for a resistivity model (background resistivity + anomalies) from a configuration file.
  7. Load IP Model: load the frameword for an IP model (background IP + anomalies) from a configuration file.

Data Inversion (or Forward Modeling for Survey Design)

  1. DI workspace (or FM workspace for Survey Design): open the Data Inversion workspace (or the Forward modeling workspace). This is the master window that provides controsl for data input,  saving  output and  running the models.
  2. Forward solver set up: set up of the main forward parameters (pcg solver tolerance, iterations, boundary conditions, ...).
  3. Inverse solver set up (for Data Inversion only): set up of the main inversion parameters (number of iterations, roughness, weights, ...).

Sensitivity Analysis

SA workspace: open the Sensitivity analysis workspace.

Items:

1. Schedule

2. Data Quality Control

3. Mesh and Rho/IP Model

4. Data Inversion (Forward Modeling)

5. Sensitivity Analysis
