The version 3.50 release refined the user interface and processing engine, offering several key capabilities:

is a 1-D inversion program that handles multiple geophysical methods in a single Windows-based environment. It replaces older DOS-based applications by offering a graphical user interface (GUI) that allows you to see your data and models side-by-side in real-time. Key Capabilities and Methods

IX1D offers two primary mathematical approaches to refine your models: Blocky Inversion (Marquardt-Levenberg)

By calculating the theoretical response of a layered ground (forward modeling) and iteratively adjusting layer thicknesses and resistivities to match field data (inverse modeling), IX1D helps professionals map groundwater tables, bedrock depth, and contaminant plumes. Supported Geophysical Methods

Geoelectrical surveys, such as Vertical Electrical Sounding (VES) and Time-Domain Electromagnetic (TDEM) methods, measure the apparent resistivity of the subsurface. However, these measurements require inversion to reveal the true distribution of resistivity, thickness, and depth of geological layers.

For thin, highly resistive layers, the software can resolve the product of resistivity and thickness (transverse resistance), but not the individual values.

(released in 2019) have added stability and features like soft parameter limits. Licensed users can generally download these updates for free from the Interpex support page

Commonly used by geologists and engineers, it specializes in , which means it takes electrical or electromagnetic data collected on the surface and "translates" it into a vertical picture of soil and rock layers. Core Functionality

Click to let the Marquardt or Occam algorithm run. Within seconds, the software minimizes the Root Mean Square (RMS) error between the observed field data and the synthetic model. Aim for an RMS error below 5% for high-confidence geological interpretations. Core Applications Groundwater Exploration

This creates a "smooth" model with many thin layers, which is excellent for identifying general trends and depth to basement without needing a complex starting model.

IX1D provides flexible data import options:

Finally, while powerful, the interface is designed for . Users can manipulate models graphically and calculate a batch of soundings in the background, greatly increasing productivity. When the inversion is complete, the program allows for the export of results as images, ASCII files, or DXF, which can be integrated into other software for final map creation.

Interpex IX1D v3 represents a generation of software that prioritized over visual flashiness. It acts as a translator, taking the silent, invisible signals of the earth and translating them into clear, actionable layers of rock, water, and ore.

: Compatible with common DC resistivity arrays like Wenner, Schlumberger, Dipole-dipole, and Pole-pole.
