Meet the Emlid Flow app with the linework, coding, and more

Emlid Flow survey app

Emlid is introducing new functionality and the new name of our survey app. Meet Emlid Flow—the highly upgraded ReachView 3 app featuring the new professional survey tools. 

We have developed new features to simplify your work both in the field and the office. We have enhanced the Emlid Flow app functionality for fieldwork with easy-to-use linework and coding. For greater flexibility, we have also launched a cloud-based service that allows you to manage survey data from the comfort of the office. If you feel intrigued, let’s drill down to the major improvements.


New features for land surveyors

The updated app brings new options for geospatial professionals. We have developed long-awaited features to amplify your team’s productivity.


With Emlid Flow, you can now create the 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. Find out the detailed guide for collecting and staking out lines in our Docs.

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.

Forget about typing 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. Read more about working with codes in our Docs.

Your app is synchronized 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 from the comfort of your office—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. Check out the guides for preparing and managing projects in our Docs.
