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.

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.

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.

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Find or adjust missing or outdated local coordinate system parameters.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.
