In the fast-paced realm of modern warfare, operational success heavily depends on the accuracy and timeliness of battlefield maps. Recognizing the need for near-real-time mapping updates, the European Defence Agency (EDA) has initiated the 3D-4Land project. This innovative project aims to revolutionize how maps are updated in operational areas, ensuring they are revised on a 24-hour cycle using advanced land-based sensing technologies.

Innovative Three-Part Process
The project’s approach breaks down into three steps:
- Sense – utilizing a range of land-based sensors already deployed within the area of operation, the project captures essential geographical and situational data in real-time.
- Process – data collected is processed and interpreted to make sense of the changing landscape and tactical environment.
- Plan – finally, the processed information is integrated into decision-making processes, enhancing tactical planning and can be used to drive autonomy.
Direct Benefits for Warfighters and Autonomous Systems
The implications of this updated and accurate mapping data are profound, offering direct benefits such as:
- Situational Awareness – accurate maps are vital for maintaining warfighter situational awareness. Without up-to-date maps, warfighters cannot make informed decisions, potentially compromising mission success.
- Decision making – with rapid access to detailed updates, warfighters can make quicker, more informed decisions without having to rely on air and space assets, which may not always be immediately available.
- Autonomy – in GPS-denied environments, drones and other autonomous systems can utilize the updated maps for enhanced navigational capabilities and operational autonomy.
A Landmark European Defense Project
The 3D-4Land project is a significant collaborative effort in European defense: it stands as the largest multimillion-dollar project dedicated to utilizing digital twins for land operations.
It’s managed by EDA and funded by the Ministries of Defense from Luxembourg and the Netherlands. The consortium is led by RE-liON, along with other leading organizations: FIRIS SA, TNO, the University of Luxembourg and the Luxembourg Institute of Science and Technology.
