"1:1,000,000 National Visual Aeronautical Chart"

This chart fills a gap in China's aeronautical charts and completed data asset registration and trading at the Beijing International Data Exchange in November this year. Through the project Development of the 1:1,000,000 National Visual Aeronautical Chart, we have clarified the technical roadmap for compiling visual aeronautical charts and efficient methods for data updates. We established a comprehensive product quality control system and developed an organizational model for mass production, which is of great significance for future batch production of surveying and mapping products.

Hunan Province Low-Altitude Visual Chart Compilation

Detect Technology completed the Hunan Province Low-Altitude Visual Chart, the Low-Altitude Airspace Operations Management Manual, and the General Aviation Airport Operations Manual. The Hunan Province Low-Altitude Visual Chart is the first high-specification, high-quality low-altitude visual chart in the region, achieving for the first time the integration of "three markings on one chart," which is of great significance for the regularization of general aviation airports.

3D Real-Scene Navigation

3D real-scene navigation transforms low-altitude airspace into a calibratable, quantifiable, computable, manageable, and usable 3D spatial data domain. It digitizes channel elements, civil aviation elements, and low-altitude airspace planning elements within the airspace, integrating relevant aerial navigation information to construct a 3D navigation map. This provides spatiotemporal information infrastructure for low-altitude transportation, building an urban air-ground integrated three-dimensional intelligent general aviation system. This better supports low-altitude route planning, airspace corridor management, flight safety warnings, etc., ensuring safe low-altitude operations.

Airspace Planning and Refined Management

We customize low-altitude aeronautical charts, including aviation situation maps, low-altitude visual charts, thematic aviation element charts, and topographic maps at various scales such as 1:1,000,000, 1:500,000, and 1:250,000. These maps meticulously detail provincial-level airspace stratification, routes, terrain elevations, geomorphic features, and obstacle distribution, comprehensively ensuring that aircraft can "take off smoothly" and "fly safely." As crucial tools and support for low-altitude airspace planning, these charts help optimize airspace resource allocation, enhance low-altitude flight safety, reduce operational costs for the low-altitude industry, and promote the transformation of regional economies from a "planar" to a "three-dimensional" model, creating new engines for regional economic growth.

Detect Technology has consecutively undertaken the Beijing aerial photography mission for eight years. For projects requiring coordinated air-ground observation, airspace coordination and utilization are crucial. Leveraging our strengths in airspace coordination, in-depth knowledge of airspace usage rules and management systems, and comprehensive consideration of terrain, landforms, and meteorological conditions, we effectively link aerial and ground operations. We produce specialized charts for Beijing aerial surveying, effectively ensuring flight safety and operational efficiency. This year, in the complex, high-density residential and building height area of Yayuncun, Chaoyang District, Beijing, we achieved ultra-low-altitude aerial photography for the first time, collecting oblique aerial survey data with a ground resolution better than 2.7 cm. This enabled the creation of a detailed 3D real-scene model to serve the urban governance and development of the capital.

A certain technology park in Beijing covers an area of 100,000 square kilometers, with its tallest building reaching 120 meters. Due to its proximity to Beijing Capital International Airport, airspace control is stringent. Despite these challenges, we ensured both ground resolution and the overlap ratio of images captured over tall buildings. Through extensive coordination and communication, the project team, drawing on past experience and the specific requirements of this mission, formulated a feasible UAV aerial photography execution plan. Over four consecutive years of annual efficient operations, all aerial photography was completed, providing complete baseline data and updated data for subsequent application platform development.

During the flood season, the urban area experienced heavy rainfall, with multiple low-lying road sections at risk of flooding. Entrusted by the client, Detect Technology personnel arrived at the monitoring site before the rainstorm with rainproof UAV equipment, equipped with stabilized gimbals and various sensors and cameras. They completed large-scale rapid imaging in real-time, capturing information on road waterlogging conditions and clearly photographing complex road conditions including bridges, roads, and submerged points in the monitored sections. The monitoring results were promptly submitted to the relevant authorities, assisting municipal departments in efficiently organizing drainage and disaster prevention/response efforts. This also provided baseline data and a feasible practical solution for the intelligent and efficient management of municipal road monitoring.
