The Technical Chamber of Greece (TEE) has launched a new Information System for the Delimitation of Watercourses. This digital infrastructure, known as the Unified Digital Map, aims to consolidate data from various files and archives into a single geospatial system.

The project involves digitizing existing delimitations and collecting data for over 8,000 kilometers of undelimited watercourses, particularly in high-risk flood zones. The initiative is intended to assist the state, municipalities, and citizens by improving resilience against extreme weather, enhancing environmental planning, and accelerating project licensing.
