Digitising cadastral surveys is pivotal for modernising land management and urban planning. Traditional methods often involve extensive fieldwork, which can be time-consuming, costly, and challenging, especially in areas with complex terrains or limited accessibility. However, advancements in drone technology and photogrammetry software have revolutionized this process, enabling efficient and precise data collection.
A compelling example of this innovation is the project undertaken in Jardín, Antioquia, Colombia. JAB Visual, led by José Alfredo Betancourt, aimed to generate a detailed 3D model of the municipality to aid in territorial and tourism planning. The town’s traditional architecture and irregular topography posed significant challenges for cadastral updates, as many buildings had unregistered modifications, and the steep slopes made certain areas difficult to access.
To address these challenges, JAB Visual employed drone technology to capture aerial images of the area. Utilising drones like the eBee X and Phantom 4 RTK, they collected 2,254 images covering 210 hectares in just half a day. This approach significantly reduced the time and resources required compared to traditional field surveys.
The collected data was processed using PIX4Dmatic, a photogrammetry software designed for large-scale mapping. This software enabled the team to process the data in six hours, generating accurate 3D models with a ground sampling distance (GSD) of 5 cm. The resulting models provided a detailed and reliable representation of the municipality, facilitating better decision-making for infrastructure planning and management.
The integration of drone technology with advanced photogrammetry software like PIX4Dmatic exemplifies the transformative potential of digital tools in cadastral surveying. By reducing the need for extensive fieldwork and providing high-precision data, these technologies enhance the efficiency and accuracy of land management processes.
