The program can automatically generate a starting model (e.g., using the “Bostick transform” or “Zohdy method”). For better control, manually input a 2- or 3-layer guess based on regional geology.
Yes, if you need a rapid, memory-efficient, and transparent tool for 1D resistivity interpretation. It is not a substitute for 2D inversion in complex fault zones or heterogeneous landfill sites. But for groundwater exploration in sedimentary basins, depth to bedrock studies, and educational settings, Interpex IX1D v350 remains an unmatched workhorse.
Its power lies in its simplicity: by forcing the geophysicist to think in layers, it builds intuition that fancy automated tools obscure. For field crews facing a long day of VES measurements, having IX1D v350 on a rugged laptop is like having a senior geophysicist in the truck—pointing out where to dig the next borehole.

Interpex IX1D v3 represents a generation of software that prioritized computational integrity 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.
Note: If you are looking for the very latest updates, the software lineage has evolved into newer versions and suites, but v3 remains iconic in the industry for its stability and focused toolset.
Interpex IX1D V3.50 is a specialized geophysical software used for 1D sounding inversion. It is primarily designed to help geoscientists process, interpret, and display subsurface data for various electrical and electromagnetic methods. Core Capabilities
The software supports a wide range of geophysical data types, allowing for detailed 1D modeling of the earth's subsurface:
DC Resistivity & Induced Polarization (IP): Supports standard arrays like Wenner, Schlumberger, dipole-dipole, and pole-pole. It handles resistivity only or resistivity with IP measurements (chargeability, PFE, or phase).
Magnetotellurics (MT): Inverts apparent resistivity and impedance phase data.
Electromagnetic (EM) Sounding: Covers frequency-domain EM (horizontal/vertical coplanar and coaxial configurations) and transient EM (TEM) for central, fixed, or coincident loop setups.
Well Log Integration: Users can import resistivity well logs and interactively reduce them into discrete layers to refine their models. Key Features for Interpretation
Inversion Methods: Offers both Ridge Regression and Occam's inversion to generate smooth or layered models.
Interactive Modeling: Models can be adjusted by depth or thickness. A split-screen interface typically shows sounding data on the left and the resulting model on the right.
Equivalence Analysis: Includes tools to analyze the equivalence of layered models, helping interpreters understand the range of possible solutions that fit the data.
Data Handling: Features easy data entry through spreadsheets or direct import from flat ASCII and USF files. Getting Started interpex ix1d v350

Interpex IX1D V350 — Essay
Introduction The Interpex IX1D V350 is a compact, budget-oriented device positioned for entry-level users who need basic functionality without premium pricing. Although not a market-leading flagship, its design and feature set aim to balance affordability with usability, making it relevant for consumers seeking straightforward performance for everyday tasks.
Design and Build The IX1D V350 adopts a simple, utilitarian aesthetic. The chassis uses cost-effective materials that prioritize light weight and manufacturability over luxury feel. Fit and finish are adequate for its segment: seams are generally aligned, and ports are accessible. The device’s size and weight favor portability, while the cooling solution is intentionally modest, reflecting the product’s low-to-midrange thermal and power profile.
Hardware and Performance Under the hood, the IX1D V350 pairs entry-level processing hardware with modest memory and storage options. This configuration targets typical use cases such as web browsing, word processing, media playback, and light multitasking. Performance is adequate for these tasks but will struggle with sustained heavy workloads like video editing, 3D rendering, or modern gaming at high settings. The device’s storage is commonly an eMMC or budget SSD option, which delivers acceptable responsiveness for everyday use but lags behind higher-end NVMe drives.
Display and Audio The display on the IX1D V350 is serviceable for general consumption: adequate brightness for indoor use, decent color reproduction for casual media viewing, and average viewing angles. It is not intended for color-critical work. Audio output from built-in speakers is typically thin and lacks deep bass, sufficient for voice calls and basic media but not for immersive listening; headphones or external speakers are recommended for better sound quality.
Battery Life and Thermals Battery life tends to align with the device’s modest hardware—sufficient for a half to full day of light use depending on settings and workload. Power management is tuned for efficiency rather than performance. Thermals are controlled through conservative clocking and a modest fan/heatsink arrangement; under heavy load the device may throttle to maintain safe temperatures.
Connectivity and I/O The IX1D V350 includes essential connectivity: Wi‑Fi, Bluetooth, USB ports, and likely an HDMI or display output depending on the exact model variation. Port selection favors mainstream peripherals and basic external displays. Expandability is limited; upgrades to RAM or storage may be restricted or require professional service on some variants.
Software and User Experience Out of the box, the device typically ships with a lightweight operating system configuration, sometimes with manufacturer-provided utilities. The software experience emphasizes simplicity and low resource overhead. Bloatware is possible on budget devices, so a clean install or disabling unnecessary background apps can improve responsiveness.
Target Audience and Use Cases The Interpex IX1D V350 is best suited to:
Limitations and Considerations Prospective buyers should be aware of:
Conclusion The Interpex IX1D V350 represents a pragmatic choice for users whose priorities are affordability, portability, and straightforward day-to-day computing. It delivers acceptable performance for common tasks while making clear compromises in processing power, display/audio fidelity, and expandability. For buyers on a tight budget or in need of a basic secondary device, it provides reasonable value; those needing higher performance or premium features should consider stepping up to more capable alternatives.
Older versions suffered from a dated, clunky interface. v350 features a cleaner layout, dockable windows, and improved graphics rendering. The resistivity pseudo-section display now supports real-time zooming and panning.
At its core, IX1D v350 is a Windows-based interactive program designed for the processing, forward modeling, and inversion of DC resistivity sounding data. Unlike generic math packages, IX1D is purpose-built for geoelectrics. The "v350" designation indicates the version 3.50 release, which includes critical patches, UI enhancements, and compatibility fixes for modern operating systems (Windows 10 and 11).
The software excels at converting apparent resistivity curves (measured in ohm-m) into a layered earth model—typically 2 to 7 layers—showing true resistivity and thickness for each layer. This output is essential for:
Navigate to Inversion > Automatic 1D Inversion. Here, v350 offers two modes:
During inversion, watch the RMS error. v350 typically achieves convergence in 5-15 iterations. A final RMS < 5% is excellent for clean data; <10% is acceptable for noisy field conditions.
To appreciate the software, let’s walk through a typical project:
