Key Benefits of Using Drones in Urban Planning
City Modeling – Design and plan more effectively with 3D reality models that accurately reflect landform and architectural information.
Urban-Rural Classification – Obtain accurate 2D maps and 3D models of the landscape as frequently as required to ensure proper, up-to-date classification.
Corridor Mapping – Quickly map corridors such as rivers, bridges, and roads, creating accurate 2D and 3D models to facilitate maintenance and inspection.
Traditional Challenges in City Modeling
The lack of precise position data makes it difficult to align BIM designs, road vector maps, Google maps, and satellite imagery, costing time and labor. 2D designs are unable to illustrate the spatial information required to fully visualize the design. The BIM designs can be quite different from the reality model, making it difficult to visualize and verify the design.
Create City Models by Using Drone in Urban Planning
Quickly take off and fly over cities or rural areas to capture data using automated flights, reducing costs and cutting fieldwork hours. Create 3D models with accurate, geo-referenced data that can be readily fitted into the BIM models to visualize designs. The 3D models generated using photogrammetry software are compatible with a variety of GIS software, streamlining the planning process.
Traditional Challenges in Urban-Rural Classification
Classification often relies on a combination of Google Maps, physical maps, and contour maps, which are low-resolution, not updated frequently enough, and not intuitive.The environment can be complex with infrastructure such as roads, bridges, and water supply. This makes mapping difficult.Traditional 2D maps do not capture enough GIS information for an environmental impact analysis needed in infrastructure planning. A 3D model would be more ideal.
How Drones Help with Urban-Rural Classification
Surveying drones and software solutions combine multiple types of geographic information to create 2D orthomosaics and 3D models to help with classification and planning.Quickly take off and fly over cities or rural areas to capture data using automated flights, reducing costs and cutting fieldwork hours.The 2D maps and 3D models generated are compatible with a variety of GIS software, so results can be quickly visualized for timely adjustments.Aerial data collected by drones can be used to create topographic maps for additional feature analyses.
