THE APP

Everything you need to survey, in one app

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.

  • Record points, lines and areas
  • Set out straight from your drawing
  • Layers and attributes, set up once
  • Length, area and volume
  • Your own coordinate system per country
  • Sync to UNI-Cloud in the background

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 .

See it on a real site

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.

Why you should equip your teams

Surveying stops being a specialist job the moment the crew can do it themselves. Three things change on site.

Work faster and gather more data

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.

Cut cost and lower the chance of damage

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.

Fewer surprises in the ground

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.

Work to the centimetre, every time

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.

WHAT IT COSTS

Cheaper than hiring it in, from the first year

Survey Package, per working day over five years
Hiring a surveying service, per day

Based on a per day hired surveyor and the average yearly cost of the Survey Package over five years, at 255 working days.

WHAT IT DOES

Everything the app does, grouped

Measure, set out, scan in 3D, photograph and export, straight from the app. What is not there yet is marked as such.

Measure

  • Points, lines and areas.
  • Offset points, offset lines and offset areas.
  • Enter a point by hand.
  • Averaging over a set recording time.
  • Tilt compensation with the UNI-GR2.
  • Your own pole height per point.

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.

Layers and data

  • Unlimited attributes.
  • Layer groups.
  • Labels on or off per layer.
  • A coordinate system per country, with transformation grids on the tablet.

Background

  • Cadastral lines for the Netherlands, Belgium and Germany.
  • Set out inside an imported background layer.
  • Inspect the objects in that layer.

Photos and 3D

  • Photos on a point or a shape, with EXIF and bulk actions.
  • Photos sync to UNI-Cloud on their own.
  • LiDAR 3D scanning on iOS devices with LiDAR.
  • Photos and scans land on the map on the centimetre, on the position of the UNI receiver, not on the tablet's own GPS.

Export and sync

  • CSV, DWG, DXF and TXT straight from the app.
  • Real-time sync.
  • View, edit and delete your exports.
  • Importing runs through UNI-Cloud, and the app links you there.

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.

How it works

STEP 1

Set up the project in UNI-Cloud

Layers, attributes and the coordinate system, once, from the office.

STEP 2

Measure on site

Open the app, connect the receiver, record and set out straight from the drawing.

STEP 3

It is in the office before you are

Background sync puts every point in UNI-Cloud.

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. Included in the UNI-Collect Survey Package for the first year.

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

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 straight into the project. It is on the tablet at the next sync.

Importing a CSV file with coordinates into UNI-Cloud

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.

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.”

T. Van de Haterd

The Netherlands

Frequently asked questions

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.
