Emlid Flow Survey Plan (1-Year)

Emlid Flow is an easy-to-use land surveying app for iOS and Android, designed for full control of Emlid Reach receivers in the field. It handles all your fieldwork – from configuring base/rover settings and connecting to NTRIP, to collecting points and stakeouts – with a user-friendly interface.

Its cloud companion, Emlid Flow 360, is a web-based service that keeps your projects **in sync** between field and office. With Flow 360 you can prepare projects on a computer (choose coordinate systems, import CAD files, etc.), and all data syncs to the mobile app (and vice versa) as soon as you’re online.

The Emlid Flow Survey Plan (1-Year) is a subscription license that **unlocks all professional features** of Emlid Flow and Flow 360. It includes everything in the free standard version of Emlid Flow, **plus** advanced capabilities for streamlined surveying workflows – such as linework and coding, CAD drawing support, expanded stakeout tools (including surfaces and stakeout reports), multi-point localization, and more. Below is a comparison of the Free vs Survey versions of Emlid Flow:

Project Management & Cloud Sync

Seamless field-to-office integration is at the heart of Emlid Flow. With an Emlid account, your projects and survey data are automatically synchronized to Flow 360, the cloud-based platform. This means you can create or organize projects on a computer (adding coordinate systems, preparing code lists, etc.), and then access them on your mobile device in the field.

Likewise, data collected on the Emlid Flow app (points, lines, etc.) is backed up to the cloud and instantly available in the office. The Survey plan uses a single login subscription for both the mobile app and Flow 360, ensuring that all advanced features are enabled and your data stays consistent across devices.

Coordinate Systems & Localization

Emlid Flow includes a comprehensive coordinate system library with thousands of EPSG codes, projections, and geoids, so you can work anywhere in the world with the correct datum. You can select predefined coordinate systems or manually enter custom parameters.

The app even supports base shift in the free version – allowing you to align your project to a known point (for example, shifting to a local benchmark). The Survey plan adds true Localization capability, enabling multi-point site calibrations: you can collect several known control points and Emlid Flow will compute a best-fit transformation to your local coordinate system. This is critical for jobs like local site grids or ground control where you need your rover to match an existing survey coordinate system.

CAD & Data File Support

Broad file support in Emlid Flow ensures you can easily import and export survey data with other software. Even with the standard (free) version, you can import or export points and geometry in common formats including CSV (point lists), DXF (CAD drawings), Shapefile (SHP) for GIS, and KML for Google Earth. The Survey subscription further enhances CAD integration: you can import full CAD drawings (e.g. DXF files with linework) into your projects as background layers for reference and stakeout.

This means you can see engineering plans or site maps right in the app while you survey. Additionally, the Survey plan enables rich mapping context with Satellite imagery and custom WMS/WMTS map layers in both Emlid Flow and Flow 360, giving you up-to-date ortho maps or other GIS data overlays directly in your survey project.

Advanced Stakeout Tools & Automation

The Emlid Flow app provides intuitive stakeout functionality to guide you to points or along lines. In stakeout mode, you’ll see distance and direction indicators (East/North offsets, plus “straight to line” distance for linear features) to help you find the exact spot on the ground. All basic stakeout capabilities are available for free, but the Survey plan greatly extends these tools.

With Linework enabled, you can stake out not just points but also lines and polygon vertices from your design drawings. The Survey plan also introduces Auto-Collect, a feature that automatically records a point once your rover remains within a specified accuracy threshold – this speeds up data collection while ensuring quality (for example, auto-measure a point after 5 epochs of FIX solution within 2 cm tolerance).

After stakeout or collection, you can generate stakeout reports (in PDF/CSV) summarizing designed vs staked coordinates and elevation deltas, which is invaluable for quality assurance and as-built documentation.

3D Data Handling – Surfaces & Cut/Fill

One of the standout features unlocked by the Survey plan is the ability to work with 3D surface modelsLandXML format (for example, a TIN or digital terrain model of a site). These surfaces then sync to the mobile app, allowing you to perform surface stakeout in the field. With a surface loaded, Emlid Flow will display your real-time cut/fill values – showing how far above or below the design surface your current rover position is.

You can walk the site and see elevation differences to grade in real time, or stake out points on the surface (the app will tell you where to cut or fill to reach design elevation at that point). All staked points can be saved and later exported along with their cut/fill information, and you can generate stakeout reports that include these surface delta values. This 3D workflow, from importing a design surface to on-site guidance and reporting, is made simple and accessible with Emlid Flow + Survey.

Compatible Hardware: Emlid Flow (mobile app) and Emlid Flow 360 (cloud) are compatible with all Emlid Reach receivers. This includes popular models like the Reach RS3, RS2/RS2+, RS+, Reach RX, as well as the Reach M2/M+ modules. In practice, any Emlid Reach device can be configured and used with Emlid Flow for data collection and stakeout, with project data syncing to Flow 360 for further management.

Can I use Emlid Flow without an internet connection?

Yes. The Emlid Flow mobile app is fully capable of offline use in the field. You can collect points, stake out, and configure your receiver without an internet connection. If you’re logged in with your Emlid account, any changes or new data you collect will be saved locally and then **synchronized** to your Emlid Flow 360 cloud account once your device goes back online. This offline-first design ensures you won’t lose data if you work in remote areas – your projects will simply update to the cloud when connectivity is restored.

What file formats can I import and export with Emlid Flow?

Emlid Flow supports importing and exporting survey data in all the common formats needed for GIS and CAD interoperability. You can import existing project data (or background maps) and export your collected survey points in CSV (comma-separated values spreadsheet), DXF (CAD drawings), SHP (Shapefile) for GIS, and KML for Google Earth. These formats cover typical use-cases like point lists, linework, and map overlays, allowing you to easily move data between Emlid Flow and other software platforms.

Will my data sync between the mobile app and the cloud?

Absolutely. As long as you are signed in with your Emlid account, your survey projects and data stay in sync. Any project you create or edit in the Emlid Flow mobile app is automatically backed up to Flow 360 (cloud) when you have connectivity. Likewise, if you upload or modify data in Flow 360 on your computer, those changes will sync down to your mobile app. This live synchronization means your field crew and office team are always looking at the same up-to-date information. It’s a seamless way to ensure data integrity and avoid manual transferring of files.

How do I activate the Emlid Flow Survey Plan after purchase?

Upon purchasing the 1-Year Survey Plan (for example, from Advexure), you will receive an activation code or license instructions. Activating the subscription is simple: log in to your Emlid account on the Emlid Flow app or via the Flow 360 web portal, navigate to the subscription or profile section, and enter the provided code (under “Have a code?” in Flow 360). Once applied, your account will be immediately upgraded to the Survey plan. All the premium features will unlock on both the mobile app and Flow 360 for the duration of the subscription. (If you were already on a trial or monthly plan via the app stores, you may need to cancel that to apply the code – see Emlid’s docs for details.) After activation, just restart the app (if needed), and you can start using the advanced tools right away.

Is the subscription tied to one device or to my account?

The Emlid Flow +Survey subscription is linked to your Emlid account, not to a single device. This means you can sign in with the same account on multiple devices (e.g. a phone and a tablet, or multiple team members’ devices) and all will have access to the Survey plan features under that account. Similarly, the subscription covers both the mobile app and the Flow 360 web service simultaneously. You are free to use any compatible device – the license isn’t locked to hardware, it’s simply tied to your login. Just remember that the subscription is intended for one user account; if you need to equip multiple surveyors with premium features, each would have their own subscription (or you can share the one account, though that also means sharing the project data).

What platforms and operating systems does Emlid Flow support?

The Emlid Flow mobile app is available for iOS (Apple) and Android devices – you can download it from the App Store or Google Play. This lets you use Emlid Flow on iPhones, iPads, Android smartphones, and tablets in the field. Emlid Flow 360, on the other hand, is a web-based application accessible through any modern web browser. You can log in to Flow 360 on a Windows PC, Mac, or any computer (or tablet) with a browser to view and manage your projects. There’s no special software required for the cloud side – just an internet connection and a browser. And regardless of platform, all Emlid Reach receivers are supported through these apps, so you can mix and match devices as needed while maintaining full compatibility.
