AGI EarthImager 3D

AGI EarthImager 3D is a three-dimensional resistivity and induced polarization (IP) inversion modeling software. It converts electrically gathered data and converts it into a 3D rendering presented using an advanced volume display.

EarthImager 3D is ideal for resistivity imaging—even in areas where there is a large topographic variation—without producing a noisy image. The final image can be rotated in any orientation, zoomed in and out, and translated to anywhere inside the image window in order to see the feature of interest in three-dimensional detail. It may show the shape of a hidden cave, the volume of a detected ore body, or the extent of an environmental spill plume.

AGI EarthImager 3D Use Cases

EarthImager 3D is for use in geotechnical and geologic industries, including the following applications:

  • Outlining the shape of caves and voids.

  • Calculating the volume of caves and voids.

  • Visualizing the bedrock surface.

  • Pinpointing precise well location for groundwater exploration.

  • Outlining the shape of an ore body during mineral exploration.

  • Calculating the volume of an ore body during mineral exploration.

  • Mapping the extent of environmental spills.

  • Monitoring the progress of an environmental clean-up procedure.

  • Calculating volumes and extent of sand, gravel, or clay during aggregate mapping.

One example of AGI EarthImager 3D at work is when imaging a cave. If you discovered the cavern using 2D imaging software, you wouldn’t be able to tell where you needed to drill in order to hit an exact location, as objects to the side of the 2D survey line gets “folded” in on the 2D image. This happens because the injected current does not simply flow downwards into the ground, but flows through the ground in all directions. 3D imaging does not have this limitation, as it can take spatial data and model the geometries in the correct location—ensuring that your drilling location is exact and accurate for more precise projects.
