The aeronautical digital space, oriented towards the aviation domain, focuses on key technologies such as pan-spatial data modeling, spatial analysis and computation, and visual representation to build a digital twin spatial foundation for aviation. This enables the representation of spatial objects such as environments, physical entities, and behaviors. Aligning with the trends in intelligent algorithms and visual representation technologies, Aviation Digital Space holds future potential for applications in numerous scenarios, including navigation visualization, low-altitude economy, and intelligence processing.
