Efficient data collection and stakeout
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
Emlid Flow has a wizard for manual coordinate system creation for areas without a predefined coordinate system. To start your survey, you just need to specify the datum, enter transformation parameters or projection, and choose your geoid.
Intuitive stakeout tool
Emlid Flow displays East-North and straight-to-line distances and supports cut and fill indication. When you get close to a point, the indication switches to a close-up alignment mode helping you to center exactly above the point.
Additionally, the app comes with a close-up alignment tool for when you need to be precise.
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 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
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!

“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.”
-
“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.”
Emlid Flow is the single app you’ll need in the field
Configure and control Reach receivers
Monitor your Reach receivers
All the necessary status information is available at your fingertips: satellite reception, solution status, modem reception, corrections stream state, and battery charge level.
Configure your base and rover
Emlid Flow allows you to set up your Reach receivers for any scenario. Pick correction sources, set up your base station, and fine-tune settings, all within a few clicks.
Manage NTRIP profiles
Store all accounts for NTRIP services in one place. You can use the same correction input settings for several Reach units after only entering the credentials once.
Raw data logging
All Reach receivers of RS- and M-series log industry-standard RINEX files for PPK workflows. Reach-produced RINEX logs from multi-band Reach receivers are compatible with popular PPP services, so that you can get centimeter-precise results anywhere on Earth.
