How do I make a Command File (.cmd) with EarthImager 2D or 3D?

Watch the videos or follow the steps below to make a .cmd file using EarthImager 2D or 3D.

To learn how to create a Command File using the SuperSting Administrator, view this article.

Creating a Command File in EarthImager™ 2D:

 

1. Open EarthImager 2D and select the Tools button from the menu on the top

2. In the menu choose Command Creator 2D

3. To set up electrode geometry, choose the Surface or Borehole Tab on the menu depending on your survey type.

For surface electrode geometry:

  • Enter first electrode address number and X(m) coordinate value
  • Enter the number of electrodes
  • Enter Electrode spacing
  • Choose “Add Surface Electrodes” to create surface electrode geometry

For borehole electrode geometry:

  • Add a borehole
  • Enter the top electrode address
  • Enter the top electrode X(m) coordinate
  • Enter the top electrode Z(m) coordinate
  • Enter the number of electrodes
  • Enter electrode distance
  • Add to create the borehole electrode geometry

4. Choose the Setting Tab and set the instrument type, array type, and other settings:

  • Choose SuperSting R8, R1 or Sting R1 from the Product Type drop down menu.
  • Choose an array from the Array Type drop down menu.
  • If you're creating a reciprocal measurement, select the Reciprocal box
  • If you're doing reverse measurements, select the Reverse box.
  • Choose signal strength values if you want any restrictions for creating the commands with average resistivity and current values.
  • Choose the maximum number of measurements or maximum acquisition time if you want any restrictions for creating the command file.

5. Choose Create Tab for creating the commands.

6. (Optional) Choose Simulation and Start Tab if you want to simulate how the measurements will be performed:

  • You can change the simulation speed and symbol size
  • You can choose forward or reverse simulation direction
  • You can enter the command line number and make manual stepping simulations
  • You can also load & simulate any previously created command file
  • You can also choose different Survey Time estimation parameters to simulate survey times

7. Finally, choose the Save Tab for saving the command file.

 

Creating a Command File in EarthImager™ 3D:

 

1. Open EarthImager 3D and select the Tools button from the menu on the top

2. In the menu choose 3D Command Creator

3. To set up electrode geometry, choose Surface Tab on the menu:

  • Choose what unit of length you want to use (meters or feet) in Length Unit
  • Enter the total number of electrodes
  • Enter the number of electrodes in X direction
  • Enter the number of electrodes in Y direction
  • Enter the electrode spacing in X direction
  • Enter the electrode spacing in Y direction
  • Choose Cable Orientation in X or Y direction
  • Set Electrode Geometry to create a rectangular grid surface electrode geometry

4. Choose the Setting Tab and set the instrument type, array type, and other settings:

  • Choose an array from the Array Type menu.
  • Choose SuperSting R8, R1 or Sting R1 from the Product Type drop down menu.
  • If you're creating a reciprocal measurement, select the Reciprocal box
  • If you're doing reverse measurements, select the Reverse box.
  • Choose the maximum number of measurements or maximum acquisition time if you want any restrictions for creating the command file.
  • Choose No Cross-String Data if you want to collect the data at the same string

5. Choose Create Tab for creating the commands.

6. (Optional) Choose Simulation and Start Simulation Tab if you want to simulate how the measurements will be performed:

  • You can change the simulation speed and symbol size
  • You can choose forward or reverse simulation direction
  • You can enter the command line number and make manual stepping simulation
  • You can also load & simulate any previously created command file
  • You can also choose different Survey Time Estimation parameters to simulate survey times

7. Finally, choose the Save Tab for saving the command file.
