Works on iOS and Android, with the UNI-GR2 or any Bluetooth NMEA receiver. Start with the tablet you already carry.
UNI-Collect is the field app of the marXact system. Set the project up once, then everyone on site works from the same drawing, the same layers and the same attributes.
Works with the UNI-GR2 and with any other Bluetooth NMEA receiver.
Pair the UNI-GR2 for centimetre-accurate RTK out of the box, or connect a receiver you already own over Bluetooth as long as it outputs NMEA. The app is the same either way.
The complete UNI-Collect Survey Package, receiver, tablet, app, cloud and corrections in one case, starts at .


We bring a receiver and a tablet to your own project and let your crew take the first measurement.
Trusted by 1000+ companies
More than 10 million objects measured, in more than 40 countries.















Surveying stops being a specialist job the moment the crew can do it themselves. Three things change on site.
One person measures and sets out without waiting for a surveyor to become available. Points that used to be skipped because they cost an extra visit now get recorded on the spot, so your as-built is complete the first time.
No hired surveyor per visit and no standing around while the site waits. In the Netherlands the KLIC cable viewer is included from UNI-Cloud Professional, so your crew sees where the cables and pipes run before the first spade goes in.
Load your existing drawings and background layers into the project before the crew arrives, so everyone works from the same picture of what is already there.
RTK corrections give a centimetre-accurate fix in the field. Everyone in the crew measures the same way, in the same coordinate system, against the same layers and attributes.
From roads to fibre, utilities to green space: record and set out to the centimetre with the same app, on any site.

Set out and check roads, sewers and foundations right in the field.

Map cables the moment they hit the trench and invoice the same day.

Record gas, water and power to the centimetre for the energy transition.

Design and set out gardens, parks and sports fields on site.

Set out stages, fences and cable runs, and reuse the same plan next year.
And much more.
Measure, set out, scan in 3D, photograph and export, straight from the app. What is not there yet is marked as such.


Coming soon: basic CAD drawing in UNI-Cloud. PDF reports are in the works.
Your KLIC data sits in the same project as your measurements, in the field and in the office.
Available from UNI-Cloud Professional.
Layers, attributes and the coordinate system, once, from the office.
Open the app, connect the receiver, record and set out straight from the drawing.
Background sync puts every point in UNI-Cloud.

Layers and attributes
Set them up once in the office. In the field your crew picks them from a list, so every point lands in the right layer.

Drag and drop your files
Drop a drawing or a point file straight into the project. It is on the tablet at the next sync.

Import and export
Bring in a full AutoCAD drawing with automatic layer mapping, names and colours kept. Export to DWG, DXF, LandXML, CSV, TXT or GeoJSON.

Our own support team in Hilversum answers the phone during office hours, on a local number in the Netherlands, Germany and the UK. Those three numbers are an extra, not a limit: we help customers worldwide, by phone, email and chat, in several languages. What customers tell us most is that we keep them moving. Someone picks up a kit from a colleague, has never used it before and calls to ask how to set it up: that is usually sorted on the phone in a few minutes. If talking it through is not enough, we can take over the receiver remotely and look at it with you. For the harder cases we stay on it until you can get on with your work.
“Measuring tapes are a thing of the past. With the UNI-GR2 we are now able to equip every worker, foreman or technician in the field with an easy to use receiver to survey.”

The Netherlands
“By using the UNI-GR2 and combining it with our GIS tools, we have been able to work more efficient. On fibre optics projects, we are now able to skip about 50 process steps!”

The Netherlands
“The stake-out function saves us a lot of time, with quick loading of points and lines. It’s easy to use, which is a big plus. We use the UNI-GR2 for baseline measurements, construction work, and sewer projects, and we’re very satisfied with it.”

The Netherlands
Survey everything yourself without waiting for a third party, and send your data straight to the office.
Record points, lines and areas, set out straight from your drawing, and work with the layers and attributes you set up in advance. Photos sit on the point you took them at, and exports go out as CSV, DWG, DXF or TXT.
Get your data from the field to your (home) office in real time. Whether you work on Android or Apple, it makes no difference.
You do the work yourself instead of booking a surveyor for every visit. Over five years the Survey Package works out cheaper than hiring one in.
We come to your site, pair a receiver and let your own crew take the first measurement.
