EM Survey Design

Setting the relevant expectation about what electromagnetic (EM) imaging can provide or NOT is critical before or after an EM survey. By combining the three other apps: 1) detectability, 2) inversion, 3) depth of investigation, this app provides a capability to evaluate the feasbility of the survey or the obtained resistivity model (after the survey).

Usage

App parameters

  • EM system: AEM or tTEM

  • Simulation or Inversion:

    • Sim: Simulation mode
    • Inv: Inversion mode

  • z: depth to the layer

  • h: thickness of the layer

  • rho_b: background resistivity

  • rho: layer resistivity

  • % error: percentage error

  • threshold: a threshold value to determine depth of investigation (DOI).

Plotting parameters

  • Resistivity range: range of resistivity shown in the left panel
  • Depth range: range of depth shown in the left panel
