Hauz Khas – Drone Survey to Help Redevelop Delhi
The Delhi Development Authority (DDA) is embracing the future of surveying by launching an ambitious campaign to map and revitalize the sprawling green spaces of Hauz Khas. Moving away from traditional manual surveying methods, the DDA is utilizing high-resolution photogrammetry paired with Differential Global Positioning System (DGPS) technology to capture the landscape from above. This aerial initiative is designed to generate precise orthomosaic maps and detailed 3D models of the terrain, covering key locations such as the District Park opposite RK Puram and the popular Rose Garden. By processing thousands of aerial images into dense point clouds, the project creates a comprehensive digital dataset that captures every contour, tree canopy, and built structure with remarkable fidelity.

The significance of this project extends towards data-driven urban management. In a city as dense as Delhi, maintaining the ecological balance of “green lungs” is vital. The centimeter-level accuracy provided by this survey allows planners to design more effective irrigation systems, optimize walking paths, and monitor vegetation health with precision. Furthermore, the 3D models serve as an essential tool for identifying and checking land encroachments, which is a persistent challenge in the region. By creating a 3D model of the parks, the DDA can simulate redevelopment plans virtually, ensuring that any physical changes are both sustainable and beneficial to the community before ground is even broken.
This high-tech revamp is slated for completion within a tight 45-day window. The survey specifically targets four major zones, signaling DDA’s commitment to modernizing India’s horticultural planning. For professionals in the geospatial field, this project highlights the growing utility of photogrammetry in civil engineering and environmental conservation. It serves as a prime example of how remote sensing technology can be leveraged to protect and enhance urban biodiversity, setting a new standard for how cities document and care for their natural assets.
