Ground Scanner Software and Data: Exporting, Saving and Interpreting Scans
3D ground scanner software takes the raw sensor readings collected along your scan lines, arranges them into a grid, and draws them as colored 2D maps and 3D plots so you can spot anomalies. Good results depend on three things: setting up the scan parameters correctly before you walk, saving every scan with enough notes to make sense of it later, and understanding how display settings such as color scaling and smoothing can exaggerate or hide what is really in the data.
This guide walks through the typical data workflow for handheld ground scanners, the settings that matter, how to organize and export scans, and the most common interpretation traps created by the software itself. Every manufacturer's software differs, so use this alongside your unit's manual.
How the data flows from sensor to screen
- Measurement. The probe takes a reading at each "impulse" point as you walk a line, either automatically at a set rate or manually at each step.
- Grid assembly. The software places each reading by line number and position along the line.
- Interpolation. Gaps between readings are filled mathematically so the result looks like a continuous surface.
- Display. Values are mapped to colors and, in 3D views, to height. Many handheld systems use the height of the 3D plot to show signal strength rather than measured depth.
- Analysis tools. Depending on the software, you can rotate the view, filter, adjust contrast, mark targets and estimate size or depth.
Some systems show results on the main unit's screen; others send data to a tablet app. Mega Detection, for example, supplies an Android tablet with its Multi Visual Analyzer app with models such as the Gold Star 3D Scanner and Infinity Max Pro, according to the manufacturer.
Setting up 3D ground scanner software before you scan
Most interpretation problems start before the first step is taken. Check these settings every time:
| Setting | What it controls | Practical tip |
|---|---|---|
| Field length and width | Size of the scanned area | Make the area large enough that any target sits well inside it, with background ground on all sides |
| Number of lines | Spacing between passes | Closer lines give better resolution; wide spacing can miss or distort small targets |
| Impulses per line | Readings taken along each line | More readings give more detail but demand a steady pace |
| Parallel or zigzag mode | Whether every line starts at the same edge | Parallel mode reduces direction-related striping; zigzag is faster |
| Automatic or manual impulses | Timed readings or one per step | Manual mode suits rough ground where a steady pace is impossible |
| Sensor height and orientation | Distance to ground and probe angle | Keep both constant for every line |
Saving scans: a simple system that works
A scan without context is hard to use a week later. Build a habit around every save:
- Consistent file names. For example: site code, date, scan number and direction, such as "FARM-N 2026-10-03 S04 EW".
- Field notes. Record grid size, line count, mode, start corner, line direction, soil moisture and anything nearby that could interfere (fences, vehicles, power lines).
- Location. Note GPS coordinates of the start corner and photograph the area with a marker at the starting point.
- Paired scans. Save the crosswise repeat scan with a matching name so you can compare them side by side.
- Backups. Copy scans off the device or tablet after each outing. Devices get lost, dropped and reset.
Exporting and sharing data
Export options vary widely between brands and models. Typical possibilities include screenshots of 2D and 3D views, image exports, and the manufacturer's own data files that can be reopened in its software. Some packages allow export of the underlying values in a general format, but many do not. Before buying, ask:
- Can scans be saved on the device, the tablet or both?
- Can raw values be exported, or only images?
- Is desktop software available, or only a mobile app?
- How are software and firmware updates delivered?
- Will older scans remain readable after updates?
Professional ground penetrating radar systems use their own processing software and data formats, and interpretation is a specialist skill. If you are deciding between technologies, see 3D ground scanner vs GPR.
Display settings that create false targets
Automatic color scaling
Many programs stretch the color scale to fit the highest and lowest values in each scan. On empty ground, that means tiny natural variations get the full red-to-blue range, and an ordinary patch of soil can look like a dramatic target. Always check the actual value range or compare against a scan of known empty ground on the same site.
Heavy smoothing or interpolation
Smoothing makes images look cleaner but can merge separate objects into one blob, round off sharp edges and spread a small anomaly over a larger area.
Exaggerated 3D height
Vertical exaggeration turns small bumps into tall peaks. It is useful for spotting features but misleading for judging how strong an anomaly really is.
Edge effects
Readings at the edges of the grid have fewer neighbors, so interpolation there is less reliable. Anomalies sitting on the border deserve a new scan centered on them.
Depth and size calculators
Depth and size estimates rely on the manufacturer's algorithms and assumptions about the target. Treat them as rough guides; field results depend on soil, target size and shape, and operator technique.
Build a reference library with known targets
The fastest way to learn what your software is really showing is to scan things you already know. On your own property, with utilities marked, bury a few known objects at measured depths and leave one area empty:
- A small non-ferrous object, such as a brass or aluminum plate
- An iron object of similar size
- A larger metal container
- An empty plastic container or a small sealed air space to imitate a void
- A control area with nothing buried
Scan each one with your normal settings, then again with different line spacing, smoothing and color scaling. Save all of them in a "reference" folder. Over time you will see how your unit displays ferrous and non-ferrous targets, how depth affects the image, how the empty control area looks under automatic color scaling, and how much your own walking technique changes the result. Repeating the reference scans in wet and dry seasons shows how soil moisture affects your site.
Turning data into decisions
Software is a tool for deciding where to look next, not a verdict on what is buried. A sound sequence is: scan, rescan crosswise, compare, tighten the grid on persistent anomalies, then confirm with an induction coil or pinpointer before digging.

Frequently asked questions
Do 3D ground scanners need a computer?
Not always. Many show results on the main unit's screen, and some pair with a supplied tablet app. Check whether desktop software is offered if you want to review scans on a larger screen.
Can I export ground scanner data to other software?
It depends on the model. Many systems export images and proprietary files only. Ask the manufacturer or our team before buying if raw data export matters to you.
Why does an empty area look like a target in my software?
Automatic color scaling often stretches tiny variations across the full color range. Compare with a known empty scan or check the actual value range.
How should I store scans long term?
Copy them to a computer or cloud storage after every outing, keep consistent names, and store your field notes and photos with them.
Does better software mean deeper detection?
No. Software can make data easier to read, but it cannot add information the sensor did not capture. Depth depends on the sensor, the target and the ground.
