Nearmap, known for providing cloud-based subscription access to up-to-date 2D orthomosaic aerial imagery, is now offering high-resolution oblique imagery and derivative 3D products. The company is using its patented HyperCamera2 technology to acquire the 3D data.
“This level of detail and scale of coverage of oblique imagery has never been available as a ready-to-use service for commercial and government needs until now,” says Patrick Quigley, senior vice president and general manager, U.S. of Nearmap. “The HyperCamera2 process maps reality by capturing the tops, sides and view angles of locations, buildings and objects, providing specific details of what’s exactly on the ground.”
Because the new camera system provides a high degree of overlap from different angles, Nearmap can reconstruct the real world in detail, producing not only high-resolution orthomosaic and oblique imagery, but also surface and terrain models, natural color point clouds and textured 3D meshes.
Soon, users can immerse themselves in 3D textured mesh models, improving analysis and design activities. They can see different elevations and line of sight using the 3D information. These features are important in many use cases, including airport or utility planning, or to determine the best location for a crane before a construction project. Other applications include wireless telecommunications network modeling, solar panel design, tactical resource deployment, real estate development promotion, property valuation, insurance underwriting, and smart cities.
“3D brings a whole new aspect of mapping reality to both commercial and government organizations,” says Rob Newman, CEO and managing director of Nearmap. “This new service will help industries plan, design, estimate, communicate and execute their plans — everything from major construction projects to solar installations on homes and businesses.”
Nearmap has already surveyed oblique images in Las Vegas; Indianapolis; Austin, Texas; Omaha, Neb.; Phoenix; Seattle; Denver; Kansas City, Kan.; Chicago; and New York. New areas are continuously added. By the end of 2017, Nearmap plans to complete surveying the largest urban areas covering more than half of the U.S. population; about 150 million people.
Nearmap imagery will be refreshed up to three times per year in these coverage areas, with three orthomosaic captures incorporating one oblique capture. Nearmap’s orthomosaic imagery already covers nearly 70 percent of the U.S. population dating back to 2014. “This gives our customers the aerial imagery services they need for their businesses and projects,” Quigley says.
Nearmap’s oblique imagery can be accessed in the MapBrowser interface or integrated into a customer’s own Web application using Nearmap’s industry-standard API. Digital surface modeling is also available for export into GIS/CAD tools, including Esri’s ArcGIS Pro. Nearmap will soon enable similar access to the 3D products.
Nearmap captures, manages and delivers current location content, allowing businesses and governments to explore their environment easily. Its high-resolution, frequently-updated aerial imagery is 2.8-inch GSD. Delivered within days of capture, Nearmap shows changes over time.
