Emlid has launched Emlid Flow - a mobile app for land surveying featuring new professional survey tools.

Emlid Flow is an upgraded version of Emlid's ReachView 3 app, with enhanced features.

The app has enhanced functionality for fieldwork with easy-to-use linework and coding, while the new Emlid Flow 360 brings a cloud-based service to enable the remote management of survey data.

Emlid Flow and Emlid Flow 360 simplify workflows in the field and the office. A free standard version is available, or take out a paid-for subscription to access the Survey package, which has more features.

heliguy™ has partnered with Emlid to add the company's range of industry-leading GNSS receivers, such as the Reach RS2+, to our surveying product ecosystem to help professionals streamline and bolster their end-to-end surveying workflows. The new Emlid Flow can be used in conjunction with Emlid receivers.   

Emlid Flow: Key Features

The updated app brings new options for geospatial professionals, featuring long-awaited features to increase productivity.


With Emlid Flow, you can now create linework on the go. Measure and move ahead with just a few taps. Make data collection a breeze using predefined geometry types or a full-blown code library. The linework is displayed immediately, so you can always see how your project is progressing.

While staking a line using Emlid Flow visual guides, you can easily navigate to a line, and stake out a line with an offset and with a chainage.





Emlid Flow supports the coding of points and lines during collection in the field. This enables you to measure and describe objects seamlessly.

Upload your custom code library or use a standard one built into Emlid Flow, which has more than a hundred codes available from the start.




There's no need to type the description for each point and line, just choose a code from a library at your fingertips. You can quickly switch between different object codes, start or continue collecting the lines, and create new codes on the go right in your survey project.

Satellite Map View

One more new feature brings several map layers. Now you can switch between a standard map and satellite imagery.

**Please note that the Linework, Coding, and Satellite Map View are only available with the paid-for Survey package.

Efficient Data Collection And Stakeout

These next set of features are available with the Standard and Survey packages.

Point Collection

Collect points, write detailed descriptions, and perform quality control using the 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 centre exactly above the point.

Additionally, the app comes with a close-up alignment tool for when you need to be precise.



Emlid Flow With Reach Receivers

Use Emlid Flow to configure and control your Reach receivers: Available with the Standard and Survey licences.

Monitor 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 the 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 centimetre-precise results anywhere on Earth.




Emlid Flow 360

Your app is synchronised with a cloud-based service, Emlid Flow 360. It allows you to access and manage your survey data from the browser at

With Emlid Flow 360, you can prepare for the fieldwork remotely: Create a project, configure the coordinate system, choose a code library or upload a new one, or just import all the necessary data.

It is immediately available inside the Emlid Flow app. No need to check if the latest version is on the collector because it syncs automatically for each linked project.




When the fieldwork is done, there is no need to manually transfer files from controllers: Just log in at Emlid Flow 360, and all your field data will be safely backed up here.

The app can work offline and synchronise data to Emlid Flow 360 as soon as your phone is back online. From the cloud service, you can export or import projects in DXFs, Shapefiles, and flexible CSVs just like in Emlid Flow.




Emlid Flow Subscriptions And Features

All the features previously available in the ReachView 3 app moved to Emlid Flow and remain free with the Standard subscription plan.

As before, Emlid Flow enables you to configure Reach receivers, collect and stake out points, export and import data in CSV, DXF, and Shapefile formats. The free Standard plan also includes the core features of Emlid Flow 360: Sync with the app, create projects, and export and import data.

Emlid will continue delivering updates available for free to enable users to easily handle the fieldwork with the Emlid Flow app and keep data in sync with Emlid Flow 360.

To access new features, subscribe to the Survey plan - bringing features such as linework and coding, and with more innovations on the horizon.
