2D RESISTIVITY TOMOGRAPHY

RESITOMO v2 is used for 2.5D modeling and 2D tomographic reconstruction inversion) of DC resistivity measurements on a PC running DOS. RESITOMO can help to plan and interpret Geotechnical Engineering and Exploration surveys to delineate waste disposal sites, mineral deposits in advance of mining, and cavities in advance of construction.


RESITOMO can use any combination of vertical and horizontal electrode positions in a plane, including the surface topographic relief. Electrode arrays can be pole-pole, pole-dipole, dipole-dipole or Wenner. Algorithms employed are well known: Finite Elements (FE) for 2.5D forward modeling and SIRT for 2D reconstruction.


RESITOMO is completely menu-driven. The resistivity model is entered with the mouse and the FE grid is created automatically. All I/O is in (directly readable) ASCII format, permitting easy editing and assessment. The final image can be seen directly on the screen and can be further processed or presented with any mapping software. The three figures show an image obtained by SIRT inversion of a block model, a progressive reduction in RMS error during iterative reconstruction, and a field example of a flooded cavity (data courtesy of DMT).
