This article only applies to movement data

This article is only relevant when working with movement data, not when working with time series data.

You can read more about the differences between the two in this article.


Before you can upload any .csv files with movement data to our platform, you need to inform the platform about the structure of your data.

  • The identifier can be found in column 3

  • The longitude is stored in column 1, and the latitude in column 2

  • Column 5 contains a property "Speed" that I’m interested in

New to data uploads ? Follow the tutorial !

There is a tutorial available where you go through the whole process of uploading your movement data to the platform. That is the best starting point for people trying to upload data for the first time.

Define the structure of the data csv files

After you have created a new data set, you get redirected to the UI where you can adjust the properties of your data set.

At the top of the page, you will find the navigation bar or stepper that takes you through the process. The UI where you define the structure of your data .csv files is located under the Configure Data Properties step:

The UI offers 3 different ways to define the structure:

  1. Using a wizard. This is the recommended way when you are new to creating data sets. This is also the way that is used in the tutorial.

  2. Using a properties file. Here you define the structure by uploading a special file containing the structure of your data. The benefit is that you can store such a file next to your data so it’s easy to re-use. The drawback is that creating this file is not super-intuitive.

  3. Copy from another data set. When you have already created another data set which uses .csv files with the exact same structure, you can instruct the platform to copy that structure from an existing data set instead of having to re-define it.

More details on each of these methods are listed below.

Using the wizard

Each data set should have at least an Identifier, Longitude, Latitude, and Timestamp columns. The wizard asks you to define which columns in your data are used for these:

  • Identifier: This should be the identifier of the vehicle, trip, asset, device,…​ being tracked. This way the platform knows to which vehicle, trip, etc. the location record belongs. Multiple records will have the same Identifier. It should not be the unique id of the record, but instead the id of the thing or person being tracked.

  • Longitude: The x-coordinate, or longitude coordinate, by default in the WGS-84 coordinate reference.

  • Latitude: The y-coordinate, or latitude coordinate, by default in the WGS-84 coordinate reference.

  • Timestamp: The date and time when the vehicle, etc. was at the location corresponding to the record.

After defining these mandatory columns, you can define additional columns to be used, by clicking the ADD PROPERTY button. A property can be free-form text (like the name of a vessel), an enumeration (like the brand of a car), or a numeric value (like the velocity of an aircraft).

Read the info messages on the right-hand side of the wizard

While you are using and going through the wizard, the info messages on the right-hand side of the wizard provide more information.

Using a data properties file

A data properties file is a CSV file describing the different columns. Each row in the CSV file specifies what kind of data a column contains.

  • Row 1 specifies the properties of column 1 in the data CSV file,

  • Row 2 the properties of column 2,

  • …​

The structure and syntax of this data properties file is explained in detail in this article.

Once you have got such a file, you can upload it by drag-and-dropping it on the drop area:

Copying from another data set

In case you already created a data set before, and your new data set follows the same structure, you can simply copy the data properties definition.

Select the data set from which the record structure information should be copied from the dropdown and press the Copy button.

Define the structure of the metadata csv files

Defining the structure of the metadata csv files is similar to how you do that for data files.

The UI looks identical and can be found under the Configure Metadata Properties button:

Figure 5. The Configure Metadata Properties button in the top navigation bar when creating or editing a data set

It offers the same options:

  • Use a wizard

  • Upload a properties file

  • Copy the structure from another data set

Mandatory properties


The definition of the data .csv files must at least define the columns of the following properties:

  • The identifier of the record

  • The longitude or x-coordinate

  • The latitude or y-coordinate

  • The time of the recording


The definition of the metadata .csv files must at least define the columns of the following properties:

  • The identifier of the record

Verifying your properties match your data files

If you’re unsure whether you’ve defined the properties correctly, you can use the validator to check.

Figure 6. The data validator UI, which appears once you’ve defined the properties

The validator allows to upload a data file to the server, and the server will validate its contents against the defined properties.

In case there is a problem parsing your data file, you still have the opportunity to update your properties before you start adding data to the data set.
