Efficient data collection and stakeout

Point collection

Collect points, write detailed descriptions, and perform quality control using our responsive interface. The app has built-in support for projections, grids, and geoids and a library with hundreds of verified coordinate systems.

Coordinate systems wizard

Intuitive stakeout tool

Linework
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 survey library is perfect, so you can always create new codes on the go
right in your survey project.

Work with different background maps

Upload topographic maps, cadastral plans, and aerial imagery from WMS and WMTS sources or work with a built-in satellite map.

Localization
Adjust your coordinate system to fit the control points

Find or adjust missing or outdated local coordinate system parameters. Depending on the data provided, Emlid Flow automatically chooses the calibration algorithm that delivers the best accuracy.
All residuals are placed on a single screen, so you have the full context while you adjust.

User reviews

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!

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!

• “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.”

ReachView 3 app. 
It is great!”

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

• “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.”
