Asia Air Survey Co., Ltd has developed systems for 3D survey and drawing production using high-resolution aerial photograph image data. The method is to display 3D images by applying photographic survey technology and editing existing 3D spatial data. Land-form digital feature data in 3D space can be recognized property in space and can be created and edited appropriately. Existing 2D information can be created and edited the same way by adding 3D information to it.
