The project aims to develop an advanced 5D Multi-Purpose Land Information System (LIS) that integrates and manages diverse urban data types—financial, cadastral, architectural, engineering, and more—across 3D spatial dimensions, time, and scale. Building on existing 3D GIS technologies from the participating enterprises, the system will enable detailed representation and analysis of real estate and manmade structures throughout their lifecycle (planning, development, registration, modification) and at multiple levels of detail. The Israeli team will develop the web-based prototype, while the Greek team will create desktop add-ons, enhancing interoperability and supporting efficient, data-driven urban governance and spatial management.
