With the launch of Maxar's WorldView-3 satellite, satellite imagery for the first time became a viable alternative to costly aerial data. Anxious to complete a proofof-concept for the Japanese customer, NTT DATA procured 30 cm Maxar imagery covering 200 sq km of the surroundings of several Japanese airports in February 2015. "The pilot project provided strong proof that 30 cm images meet and even exceed accuracy expectations, especially for airports situated in more rural and sub-urban areas, which is where the majority of airports are located," said Mr. Kenji Wakamatsu. "The 30 cm imagery readily enables obstacle extraction of smaller buildings and can be used to update 3D obstacles more quickly and cost-effectively than aerial photos." Exceeding accuracy standards, NTT DATA proved that Maxar 30 cm imagery, at a cost of 70% or lower of aerial imagery, presents a viable and cost-effective option for airports around the world seeking to implement PBN. Tokyo-based Maxar master reseller NTT DATA procured WorldView-3 high-resolution 30 cm images for several airports in Japan to demonstrate that cost-effective 30 cm imagery meets the accuracy requirements of Performance Based Navigation. Find a cost-effective option to aerial imagery to create high accuracy elevation vector datasets for airports around the world, allowing them to meet the rigid requirements of Performance Based Navigation. Challenge Solution Results 30 cm imagery viable for mapping airports globally With the ready ability to capture the vertical accuracy required of PBN applications, 30 cm imagery has the potential to meet the data collection needs of more than 100 airports in Japan alone and countless others around the globe. At a cost of 70% or lower of aerial imagery, realizing the potential of PBN is within the grasp of hundreds of airports that previously faced insurmountable budget obstacles with aerial images. "Performance Based Navigation requires fast delivery and regular cost-effective updates, two characteristics that aerial imagery could not provide. Now, with the ability to create an elevation vector dataset for all significant man-made and natural obstacles around an airport with 30 cm imagery, potentially hundreds of airports will find this solution viable to finally put PBN applications in place that will deliver on the promise of more efficient takeoff and landing patterns to reduce fuel consumption and increase capacity, while minimizing the environmental impact." - Mr. Kenji Wakamatsu, Director of EO business, Public Sector, NTT DATA Corporation obstacle data obstacle extraction digital surface model
