Access Data from the European Tracking Network • etn

etn is an R package to access data from the European Tracking Network (ETN). With etn you can query metadata (animals, tags, deployments, receivers, projects) and data (acoustic detections, sensor data) from the ETN database and use these in your analyses. Data access requires user credentials and is subject to a data policy.

To get started, see:

Configure credentials.

Installation

You can install the development version of etn from GitHub with:

# install.packages("pak")
pak::pak("inbo/etn")

Usage

Before you can access data from the European Tracking Network, you need to register for a MarinePass account at the Flanders Marine Institute (VLIZ). See authentication for instructions.

With etn you can query ETN (meta)data:
