GNSS SURVEYING FOR EVERYONE

Professional GNSS surveying, made for everyone on site

Survey, set out, 3D scan and control machines yourself, accurate to the centimetre. One platform, three ready-to-use packages. No specialist needed.

Trusted by 1000+ companies

More than 10 million objects measured, in more than 40 countries.

One platform for everyone who works on site. From a single GNSS receiver to a full machine setup, everyone works from the same project.

Work faster, gather more data

Capture points, lines and surfaces in the field yourself, without waiting for a specialist to show up.

Lower cost, fewer mistakes

Skip the day rate of a hired surveyor and cut the rework that on-site errors cause.

Centimetre accuracy

RTK-corrected GNSS gives you survey-grade accuracy you can set out and build on.

WHAT IT DOES

Everything the kit does, grouped

Survey, set out, scan in 3D, import, export and share. What is not there yet is marked as such.

Measure

  • Points, lines and areas, with offsets on all three.
  • Enter a point by hand.
  • Length in 2D and 3D, per segment and the angle to the previous one.
  • Area, and volume over a surface.
  • Averaging over a set recording time.
  • Your own pole height, and tilt compensation up to 45 degrees.

Set out

  • Points, lines and areas.
  • A direction arrow to the target point.
  • Values to the centimetre.
  • A warning when accuracy drops.
  • Save what you set out, or update the existing point.

Import and export

  • In: CSV, TXT, DXF, DWG, LandXML, GeoJSON, KML and ESRI Shapefile, or a ZIP with a set of files.
  • A full AutoCAD drawing with automatic layer mapping, names and colours kept.
  • Out: DWG, DXF, LandXML, CSV, TXT and GeoJSON, in 2D or 3D.
  • Per layer, or the whole project at once.

Background and reference data

  • Cadastral lines for the Netherlands, Belgium and Germany.
  • Large drawings as a fast background layer, in the field and in the cabin.
  • WMS layers supplied by us on Professional, your own source on Ultimate.
  • A coordinate system per country, set when you create the project.
  • Transformation grids on the tablet.

Photos and 3D

  • Photos on a point or a shape, with EXIF, syncing on their own.
  • LiDAR 3D scanning with an iPad Pro, with the UNI-GR2 for accuracy.
  • Scans and photos on the map in UNI-Cloud, in a 3D viewer.
  • Photos and scans land on the map on the centimetre, on the position of the UNI receiver, not on the tablet's own GPS.

Share and work together

  • A public project link or a QR code, no account needed on the other side.
  • Users, groups and rights.
  • Real-time sync.
  • An API and WebSockets for your own integration.

Coming soon: basic CAD drawing in UNI-Cloud. PDF reports are in the works.

KLIC (NETHERLANDS)

KLIC notifications in the field and on the map

Your KLIC data sits in the same project as your measurements, in the field and in the office.

  • KLIC viewer as a layer over your project in UNI-Cloud.
  • Open and download KLIC documents from UNI-Cloud.
  • Use imported GeoJSON as a KLIC layer.
  • Use KLIC codes in UNI-Collect on the tablet.
  • Also visible in UNI-Machine in the cabin.

Available from UNI-Cloud Professional.

UNI-CLOUD

Where all your field work comes together

Every point, line and project syncs to UNI-Cloud. Plan the work, share with the office and clients, and keep the field and the desk on the same page.

Everyone who works in the project gets their own login.

Draw straight in the cloud and send a finished PDF report to your client.

UNI-Cloud project open on a desktop screen in the office

Import and export

Bring in a full AutoCAD drawing and export to DWG, DXF, LandXML, CSV, TXT or GeoJSON.

Projects

Set up layers and attributes once, use them in the field.

Real-time sync

Field data in the office the moment you save.

Share your results

Send a project to your client with a link or a QR code.

Working with layers in a UNI-Cloud project

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.

Adding a file to a UNI-Cloud project by dragging and dropping it

Drag and drop your files
Drop a drawing or a point file, or full AutoCAD drawing straight into the project. It is on the tablet at the next sync. A drawing arrives as layers with points, lines and areas.

Importing a CSV file with coordinates into UNI-Cloud

Share your results
One click gives your client a link or a QR code to the project. No account needed on their side. Export to DWG, DXF, LandXML, CSV, TXT or GeoJSON, in 2D or 3D, per layer or the whole project.

SUPPORT

Support that keeps you working

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.

  • Email and chat support on every plan.
  • Phone support and remote assistance from Professional.
  • A replacement receiver if yours fails, on Ultimate.

What our customers say

“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.”

Heijmans

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!”

BAM Infra Telecom

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.”
