Field data of the German National Forest Inventory

The field data of the fourth National Forest Inventory (BWI 2022) and the previous inventories (BWI 2012 and Carbon Inventory 2017) are public available in the form of a RESTful API for use by third parties.

The URL above is an open standard programming interface and is not intended for use with a web browser. It is provided to be used with a programming language that supports HTTP requests (e.g., R, Excel-VBA, Python, JavaScript, etc.). Such requests (API calls) can be implemented to retrieve, filter and combine data for various inventory objects.

Examples of usage and documentation of the interface are also public available on GitHub.

Simple graphical interfaces (jump start pages) are provided to help getting started easier:
Jump start into field data inventory archive
Jump start into metadata (key tables)

The jump start pages above use slightly modified OpenAPI description documents which can be found here:
OpenAPI document for the inventory archive
OpenAPI document for the key database

To use the API and the jump start pages, an API key is needed. This key can be found on GitHub.
