The Survey of India has completed a comprehensive drone survey covering approximately 550 square kilometers of Delhi, representing over one-third of the city. This initial phase included the Yamuna O Zone and 66 unauthorized colonies, with images shared with the Delhi Development Authority (DDA) and the Municipal Corporation of Delhi (MCD). The survey aims to identify encroachments on DDA land, assess structures, and facilitate their removal. Following a tripartite agreement, the DDA plans to overlay cadastral maps on drone images to monitor land status and ensure compliance with regulations, ultimately enhancing land management and resource utilization across various departments.
The Survey of India has successfully completed a drone survey covering nearly 550 square kilometers, which accounts for over one-third of Delhi, as part of the first phase of the project. The captured images have been shared with the Delhi Development Authority (DDA) and the Municipal Corporation of Delhi (MCD).
This survey encompassed the entire Yamuna O Zone, spanning approximately 97 square kilometers, as well as 66 unauthorized colonies. Officials noted that the agency is currently conducting a drone survey of the morphological ridge, which covers about 111 square kilometers.
The images obtained will assist in identifying encroachments on DDA land, assessing the type of structures and the number of floors in residential areas, and facilitating the removal of encroachments after cross-referencing with revenue records. They will also be valuable for regular monitoring of any new encroachments.
In August, the DDA entered into a tripartite agreement with the MCD and the Survey of India to address the uncertainties regarding land ownership and status among various government entities in Delhi. This initiative aims to protect government land from unauthorized encroachments and illegal construction activities.
Officials explained that the DDA plans to overlay cadastral (khasra) maps onto the drone images to identify its land and ascertain whether it is encroached upon. "We will also continuously monitor new encroachments on DDA land throughout the year," an official stated.
The drone survey was initiated following repeated recommendations from Lieutenant Governor VK Saxena, who emphasized the need to understand the current status of land. He played a key role in facilitating the collaboration among the three agencies that signed the agreement. "This issue has also been highlighted by various courts, which directed land-owning agencies to employ advanced technological solutions to accurately map land status," the official added.
The drone survey will provide high-resolution images that aid in precisely demarcating the boundaries of structures and khasra layers. Data elevation models are being utilized to detect vertical encroachments, enabling real-time data collection on encroachments and prompting authorities to take action at early stages.
Ultimately, the survey will generate geospatial data and track activities, forming a foundation for integrating information from the DDA, MCD, and other departments in Delhi, including revenue, housing, urban development, public works, flood control, environment, agriculture, and disaster management. This integration aims to optimize resource utilization and ensure comprehensive oversight across all jurisdictions.
The successful completion of the drone survey marks a significant advancement in addressing land management issues in Delhi. This initiative not only fosters collaboration among key agencies but also aligns with judicial recommendations for improved land oversight. As the project progresses, the integration of geospatial data across multiple departments will enhance resource allocation and promote sustainable urban development, paving the way for a more organized and accountable approach to land use in the capital.
