note

To start using codes, you need to create a code library in Emlid Flow 360 or use one of the default libraries and apply it to your project. Learn more in the Manage code libraries guide.

This guide describes how to work with survey codes to ease your work with survey projects in third-party GIS software.

Overview​

Emlid Flow supports two code geometry types—point and line. Point codes are used to survey designate features such as trees, utility poles, and road signs. Line codes are used to survey linear features such as fences, walls, and curbs.

Additionally, each code may have its attributes. Attributes are additional data fields attached to a survey code. They allow you to record metadata beyond position, such as material type, diameter, condition, asset ID, or inspection notes. This helps standardize data collection and ensures consistent information across projects and field crews.

caution

Currently, attributes can only be added to manually created code libraries in Emlid Flow 360. Importing code libraries with attributes is not yet supported and will be added in future releases.

Surveying with codes​

The typical workflow of surveying with codes in Emlid Flow is the following:

  1. In your project, open the Collector or Collector in stakeout menu.
caution

Attributes in the Collector in stakeout mode are currently available only on Android. Support for iOS will be added in a future release.

  1. Tap the Code selector button to open the Code library screen. Here you can see the list of codes linked to your project.

  2. Select the code you need.

  3. Start data collection.

    tip

    For a more detailed workflow, check the collect points and collect lines guides.

Creating codes on the go in Emlid Flow​

Sometimes, there might be a situation when a code library doesn't have the required code. Emlid Flow allows you to create survey codes in the field.

note

Codes created on the go are stored only in the project in which they were created.

caution

Adding attributes to codes on the go is not supported on both Android and iOS platforms. To use codes with attributes, create and configure them in a code library in Emlid Flow 360. Learn more in the Manage code libraries guide.

To create a survey code on the go in Emlid Flow, follow the steps below:

  1. Open Emlid Flow and connect to your Reach.

  2. Open or create a project.

    tip

    To learn how to create a project, check the Create or import project guide.

  3. In Collector, tap the Code selector button.

  4. Tap the Plus button in the top right corner.

  5. Fill in the fields and select code geometry type. Tap Save.

The created code will appear in your code library.


You can continue creating codes on the go in Emlid Flow and continue your survey.
