Efficient data collection and stakeout


Efficient data collection and stakeout


Collect data and create linework on the go

Measure and move ahead with just a few taps. You can use either predefined geometry types or a full-blown code library, whatever suits your needs.

Line stakeout

Navigating to a line is intuitive. With our visual guides, you can perform stakeout with an offset. The distance along the line indication will help you stake out with chainage.


Add codes to your data
Forget about memorizing code lists. Your whole library is always at your fingertips

Add codes, quickly switch between different object codes, start new lines, and continue collecting existing ones. Upload your custom code library or use a standard one built into Emlid Flow with more than a hundred codes available from the start.

Add codes on the go

No code library is perfect, so you can always create new codes on the go right in your survey project.


Work with satellite maps or any WMS source

Our responsive project view supports satellite imagery, as well as your own custom background map sources.

User reviews

Reach View 3 App
James Lamping California, USA

Emlid has redesigned the app ReachView 3 so that it is no longer a web app, but a fully native iOS or Android app. This means that you can view and export your survey points from your phone even after you disconnect from your receiver! Another really great feature that was added is the ability to choose your coordinate system and vertical datum!

Reach View 3 App
Rory Gillies Scotland, UK

We had a job observing control points for an aerial survey. It went great, surveyed straight to ETRS89 with Lerwick height. It was close to gale force winds but surveying with the RS2 is fun in any weather!

  • “Just started using the emlid 3.0 app. It’s really really good. Nice work!”

  • “Emlid has developed an upgraded app ReachView 3. It's easy to use. It has all you need for survey/mapping. Datum, projection, and geoid.”

  • “I just installed the new 
ReachView 3 app. 
It is great!”

  • “I currently use my iPhone with the ReachView app, and it works great.”

    Rob Camirand President
    of RC Drone Services
  • “It works brilliantly. I tested all the EPSG codes I need nationally, and it also allows to download a 2mb height set with a custom vertical EPSG. I use NTRIP and get a fix immediately. I switched completely from our other gear, as this is much faster. I can actually argue that I spend less than half the time surveying now.”
