Surveying and mapping
Surveying and mapping involve collecting, organizing, and analyzing spatial data to organize layers of information into visualizations using maps and 3D scenes.
This data is later interpreted into patterns, relationships, and situations using image processing software to help users make well-informed decisions.
Geographical information systems require high-resolution images in real-time. Drones built for speed and accuracy provide the ideal abilities to capture vast amounts of data with minimum manpower and time compared to conventional methods.
Modern drones use multiple payloads such as RGB cameras, multispectral cameras, LIDAR sensors that can provide a wide range of data when combined with photogrammetric software to create geo-referenced orthomosaics, digital elevation models, digital terrain models, 3D reconstructed models of the project area.
Drones provide the following advantages:-
Reduced time and cost of surveys
Drones can decrease the time of data acquisition with minimum manpower if necessary. Automated and semi-automated drones can be used to regularize monitoring and decrease costs.
Reach remote and inaccessible areas
Drones require minimum space to take off and can fly almost anywhere. They are not bound by topography or time and can be used without disrupting services.
High-resolution images with great accuracy can be used for maintaining land records, disaster mitigation, and slope measurement. This data can help identify potential landslides and prevent damage to roads, railways, and bridges.
