TL;DR: Geotechnical monitoring software collects readings from instruments such as prisms, piezometers and inclinometers, compares them with trigger levels, and reports them to the people accountable. Instrument data platforms take many sensor types at once. Survey-based tools focus on prisms and imagery. Most monitoring programs use one of each.
Key takeaways
- Monitoring software is not analysis software. PLAXIS and GeoStudio model ground behavior, while monitoring platforms record what the ground is actually doing.
- The engineer of record sets the frequency. According to the Global Industry Standard on Tailings Management, monitoring data is analyzed at the frequency the engineer of record recommends.
- Results must be reported. According to the same standard, monitoring results are reported at least annually, and out-of-range performance is handled through trigger action response plans.
- Prisms are checkpoints, not control. According to the help center of Birdi (birdi.io), prisms read from low monitoring flights reach about 3 to 4 mm of tagging accuracy.
- Thresholds need an audit trail. Recording which warning and action levels were in force is what lets an engineer explain a decision months later.
What does geotechnical monitoring software do?
Geotechnical monitoring software collects readings from instruments in and on the ground, stores them with dates, checks each one against trigger levels, raises alerts, and produces reports for the engineer, the owner and the regulator. It records what the ground is doing. Geotechnical analysis software, such as PLAXIS or GeoStudio, models what it should do, and is a different purchase.
The instruments vary by what they measure. Prisms and GNSS points measure surface movement. Piezometers measure pore water pressure. Inclinometers and shape arrays measure movement below the surface. Settlement gauges, extensometers and tiltmeters fill in the rest. Most platforms specialize in some of these, so the first question is which instruments your program uses.
Who uses it
Monitoring is usually run by a consulting engineer for an asset owner: a mine, a dam owner or a transport agency. The consultant collects the data, the engineer of record reviews it, and the owner and regulator read the reports. So access for people outside the consultant's team matters as much as the data itself. For tailings in particular, see our guide to tailings dam monitoring software.
How did we choose and compare the platforms?
We chose platforms that manage geotechnical monitoring data, and compared them on the instrument types they take, how thresholds and alarms work, whether they are real-time or periodic, data types in one view, and access for people outside the paid team. Birdi is listed first, and the order is not a ranking.
Every fact was checked on the vendor's own website or help center on October 7, 2026. None of the platforms publishes a price, apart from Birdi, so pricing is by quote throughout. We left out pure analysis software, which models ground behavior rather than recording it.
Instrument platform or survey record?
The list mixes two kinds of tool. Instrument data platforms (MissionOS, iTwin IoT, Worldsensing, Proqio, Encardio-rite) take readings from many sensor types. Survey-based tools (Birdi, Trimble 4D Control) focus on surface movement from prisms and survey data. A program with piezometers and inclinometers needs an instrument platform, whatever else it uses.

How should warning and action levels be set?
Warning and action levels should come from the engineer of record's design assumptions and the facility's risk assessment, not from software defaults. A warning level asks someone to look closely. An action level triggers a response under the trigger action response plan. Each instrument type, and often each instrument, needs its own levels.
The software's job is to apply those levels consistently and keep a record of them. When levels change, the reports produced before the change should still show the old values, so a decision can be explained later. Our guide to running a prism movement report shows how this works for prisms.
Who needs to see geotechnical monitoring data?
The consulting engineer, the engineer of record, the owner's site team and the regulator all need to see monitoring data, at different levels of detail. A consultant needs every reading. Meanwhile, the engineer of record needs trends and exceedances. Owners and regulators need banded reports they can read without specialist software.
That makes access a real selection criterion. A platform that needs a paid license for every reader pushes reports into PDFs and email, where versions multiply. A platform with viewer access keeps one record. For keeping survey control consistent between readings, see our guide to prism survey control.
Frequently asked questions
What is geotechnical instrumentation?
Geotechnical instrumentation is the set of sensors used to measure how ground and structures behave. It includes survey prisms and GNSS for surface movement, piezometers for pore water pressure, inclinometers for movement below the surface, and settlement gauges, extensometers and tiltmeters. The readings are compared with design assumptions and trigger levels.
What is the difference between a piezometer and an inclinometer?
A piezometer measures pore water pressure in the ground, which affects the stability of slopes, embankments and dams. An inclinometer measures horizontal movement below the surface, along a borehole, showing where and how fast the ground is shifting. Together they show the cause and the movement.
How often should monitoring prisms be read?
It depends on the structure, its risk and the engineer of record's design. Critical structures may be read continuously by automated total stations, while others are read at each survey, often monthly. Under GISTM, data is analyzed at the frequency the engineer of record recommends, so the frequency is an engineering decision.
What are trigger action response plans (TARPs)?
A TARP sets pre-defined trigger levels for monitored parameters and the actions to take when each level is exceeded. A range of actions is set in advance, based on how far a reading goes past its trigger. GISTM requires out-of-range performance on tailings facilities to be addressed promptly through TARPs or critical controls.
Can drone surveys support geotechnical monitoring?
Yes, as a periodic layer. Drone surveys can read survey prisms as checkpoints, at a few millimeters of tagging accuracy on low flights in Birdi's published figures, and record the whole surface between readings. They do not replace piezometers, inclinometers or real-time instruments, and the engineer still interprets the results.
