caution

If you don’t have an Emlid account or your data isn’t visible in Emlid Flow 360, do not remove or reinstall the app, as this may result in data loss. If you experience missing data, startup crashes, or any other issues with the app, please contact us at support@emlid.com.

tip

We recommend creating projects before the survey since some

coordinate systems

Coordinate system is a coordinate-based local, regional or global system used to locate geographical entities. A spatial reference system defines a specific map projection, as well as transformations between different spatial reference systems.

require additional downloads in Emlid Flow.

This guide describes how to create or import a project in Emlid Flow or Emlid Flow 360 to survey.

Overview

Projects are a way to group and operate your survey data. Using projects, you can collect and stake out data in the preferred

coordinate system

Coordinate system is a coordinate-based local, regional or global system used to locate geographical entities. A spatial reference system defines a specific map projection, as well as transformations between different spatial reference systems.

. Projects can be linked with a code library to help you manage survey data later in the post-processing.

Workflow

Every survey starts with a project.

Creating project

To create a project in Emlid Flow or Emlid Flow 360, follow the steps below:

Emlid Flow

1. Open Emlid Flow and go to the Survey tab.

   

2. Tap the Plus button in the top right corner to open the New project screen and fill in your project info.

   

3. With the subscription plan, you can link a code library to your project to work with lines and codes.

   note

   You can specify the linked code library only when creating a project.

4. Specify the coordinate system you want to work in.

   tip

   Check the Coordinate systems introduction to learn more.

5. Select the measurement units for your project from the Linear Units drop-down menu.

       

6. Select the angle display format: DD or DMS.

note

By default, all geographic coordinates, directions, and azimuths are displayed in the DD format. Alternatively, you can change this in your Profile settings: go to your profile, tap the Preferences section, and select the DD or DMS format.

6. Tap Save. Emlid Flow will open the project.

   

Once the project is created, you can start working with survey tools in Emlid Flow.

Emlid Flow 360

1. Go to flow360.emlid.com and sign up or sign in using your Emlid account.

   tip

   To learn how to create an Emlid account, check the Getting started guide.

   

2. Click + New project in the top left corner.

   

3. Fill in your project info.

   

4. With the subscription plan, you can link a code library to your project to work with lines and codes.

   note

   You can specify the linked code library only when creating a project.

5. To specify the coordinate system you want to work in, click the Edit button in the Coordinate system cell.

   note

   By default, all geographic coordinates, directions, and azimuths are in the DD format. To change this, go to your profile, tap the Preferences section, and select the DD or DMS format.

   

7. Click the Create project button. Emlid Flow 360 will open the project.

   

8. Open your project in Emlid Flow and ensure the coordinate system files are downloaded to your mobile device.

Once the project is created, you can start surveying with Emlid Flow.

Importing project data

With Emlid Flow and Emlid Flow 360, you can import your projects in the CSV, DXF, KML, or Shapefile format.

To import the project, follow the steps below:

Emlid Flow

1. Swipe up the project drawer and tap the Import button.

   tip

   You can also import the project from the Survey tab by tapping the 3 dots in the top right corner.

   

2. Tap the import format you want to use. The format requirements will appear.

   

3. Choose the project file.

   note

   Emlid Flow supports projects only with points and lines. Lines support is included only in the subscription plan.

4. Wait until Emlid Flow finishes importing the project. Once the project is imported, you will see the confirmation sign.

   

Emlid Flow 360

1. Click on the Import button on the top panel.

   

2. Tap the import format you want to use. The format requirements will appear.

   

3. Choose the project file.

   note

   Emlid Flow supports projects only with points and lines. Lines support is included only in the subscription plan.

4. Wait until Emlid Flow 360 finishes importing the project. Once the project is imported, you will see the confirmation sign.

   

Now all the objects are imported to your project.

Adding NTRIP profile

When setting up a project, you can also add an NTRIP profile at this stage to receive NTRIP

corrections

The corrections are the data that is used to eliminate ionospheric and tropospheric delays, and satellite clock errors. The static base transmits corrections to the moving rover in the RTK scenario.

during your surveys. You can create and manage NTRIP profiles in both Emlid Flow and Emlid Flow 360, and your profiles will be synchronized between the applications.

To add a new NTRIP profile, follow these steps:

Emlid Flow

1. Open the Emlid Flow app, and go to Profile.

2. Tap My NTRIP profiles.

3. Tap the blue plus button in the upper-right corner.

4. Fill in the information from your NTRIP provider.

   tip

   To find out which

   mount point

   Mount point is a correction data source related to the specific physical or virtual reference station chosen or created based on your location respectively. When you get corrections from a VRS, you need to enable sending your receiver's position in the NMEA format.

   suits you better, check the website of your NTRIP provider. The closer the

   , the more precise your solution will be.

   ANDROID KEYBOARD TECH TIP

   On some Android devices, default keyboards do not provide a minus sign. To get access to it, we recommend downloading Gboard, a virtual keyboard app, from the Google Play Store.

   

5. Tap Save in the upper-right corner.

Emlid Flow 360

1. Open the Emlid Flow 360 app and tap Profile in the upper-right corner.

2. Tap My NTRIP profiles.

3. Tap the +New button.

   

4. Fill in the information from your NTRIP provider.

   tip

   To find out which mount point suits you better, check the website of your NTRIP provider. The closer the mount point, the more precise your solution will be.

   

5. Tap Save.

Now your new NTRIP profile is saved in your NTRIP profiles list.
