Digsur has continuously undertaken and completed the aerial photography task of Beijing for eight years. In specific projects involving air - ground coordinated observation, how to achieve air - ground coordination, and airspace coordination and use is a crucial link. The company fully leverages its airspace coordination advantages, is well - versed in the rules and management systems for airspace use, and takes into account the terrain, landforms, and meteorological conditions to effectively connect the air and ground. It has produced a dedicated Beijing surveying and mapping chart, effectively ensuring flight safety and operational efficiency. This year, the company achieved ultra - low - altitude aerial photography for the first time in the complex area of Beijing's Chaoyang District, Asian Games Village, with a population and high - rise buildings. It collected oblique aerial surveying data with a resolution better than 2.7 centimeters on the ground and established a refined 3D model of the real scene, serving the governance and development of the capital Beijing.

A certain technology park in Beijing covers an area of 100,000 square kilometers, with the tallest building reaching 120 meters and being close to the Capital International Airport, where airspace control is strict. Faced with many difficulties, the project team, based on past experience and considering the particularity of this flight, ultimately formulated a feasible UAV aerial surveying implementation plan. After four years of efficient operations once a year, all aerial photography work was completed, providing complete basic data and updated data for the subsequent application platform construction.

During the flood season, when the urban area was hit by heavy rainfall and many low - lying points on the roads faced the risk of water accumulation and flooding, DiCe Tech staff, commissioned by the client, arrived at the monitoring site in time before the heavy rain with rain - proof UAV equipment, equipped with stabilized gimbals and various sensor cameras. They completed large - scale rapid imaging and obtained real - time information on road water accumulation. They clearly captured the complex road conditions of bridges, roads, and water - accumulation points in the monitored sections. The monitoring results were promptly submitted to the relevant departments to assist the municipal authorities in organizing drainage work and making efficient decisions and implementation of disaster prevention and control efforts. This also provided basic data and a practical solution for the intelligent and efficient monitoring of urban roads.

This chart filled the gap in China's aeronautical charts and completed the registration and trading of data assets at the Beijing International Big Data Exchange in November of this year. Through the project of developing the "1:1,000,000 National Visual Aeronautical Chart," the company clarified the technical route for compiling visual aeronautical charts and the efficient practice methods for data updates. It established a quality control system for the entire project and formed an organizational model for batch production. This is of great significance for completing other batch geospatial surveying and mapping product production tasks in the future.

DiCe Tech completed the "Low - altitude Visual Aeronautical Chart of Hunan Province," the "Low - altitude Airspace Operation Management Manual," and the "General Aviation Airport User Manual." The "Low - altitude Visual Aeronautical Chart of Hunan Province" is the first high - specification and high - quality low - altitude visual aeronautical chart, which for the first time realized the "three - standard - same - chart." This is of great significance for the standardized construction of general aviation airports.

Real - scene 3D navigation transforms the low - altitude airspace into a low - altitude 3D data space that can be positioned, quantified, calculated, managed, and utilized. It digitizes the channel elements, civil aviation elements, and low - altitude airspace planning elements of the low - altitude airspace, integrates relevant aerial navigation information, and constructs a 3D navigation map. This provides a spatiotemporal information infrastructure for low - altitude transportation and builds a three - dimensional intelligent general aviation system with air - ground coordination in cities. It better supports low - altitude air route planning, airspace line control, flight safety early warning, and other aspects, ensuring the safety of low - altitude operations.

Custom - made low - altitude aeronautical maps, including aeronautical situation maps, low - altitude visual aeronautical charts, aeronautical element thematic maps, and topographic maps in various scales such as 1:1,000,000, 1:500,000, and 1:250,000. These maps detail the stratification of airspace, air routes and lines, terrain elevation, landform features, and obstacles within the entire province. They fully ensure "taking off safely and flying safely." As an important tool and support for low - altitude airspace planning, low - altitude aeronautical maps help optimize airspace resource allocation, enhance low - altitude flight safety, reduce the operating costs of the low - altitude industry, and promote the transformation of regional economy from a "flat" to a "three - dimensional" model, creating a new growth pole for the regional economy.

In 2019, after receiving the task, we successively completed 11 research reports, including analysis of airspace conflicts, optimization of airspace structure, design of flight procedures, aircraft performance analysis, airspace capacity assessment, and coordination of military and civil aviation airspace issues. Within less than a year, we obtained the site selection approval from the military and civil aviation for Nantong New Airport. During the pre - feasibility study stage, we strengthened communication and coordination with the Joint Staff Department of the Central Military Commission, the Air Force, the Navy, the Civil Aviation Administration, the regional administration, the air traffic control bureau, the Eastern Air Force, the Shanghai Base, and surrounding military and civil aviation airports and troops. In January 2024, we organized the Nantong New Airport Airspace Planning Military - Civil Aviation Coordination Meeting. After the civil aviation industry review is completed, the next stage of work can be carried out.
