With the continuous transformation and upgrading of my country's "digital city" to "smart city", GIS applications based on two-dimensional vector data have been difficult to meet the needs of urban intelligent management. The important construction task of national basic surveying and mapping during the "14th Five-Year Plan" period, the urban 3D platform can provide the city's 3D base for the comprehensive management of natural resources and smart city management, and provide basic data and information for urban planning, management, fire protection, emergency response, ecological environment monitoring, etc. management platform. Therefore, how to quickly and accurately obtain 3D data in geographic space has become an important support for the 3D construction of real China. UAV oblique photogrammetry has become an important way to obtain oblique photography data due to its efficient and flexible data acquisition capabilities.

Currently, there are two main types of UAV airborne lidar. One is a short-range laser of about 250m, which is low-cost, short-range, and suitable for small-scale terrain data acquisition. The other is a long-range laser of 1500m and above, which is heavy. Large, high cost, suitable for large-scale terrain data acquisition for large models.
The successful development of DV-LiDAR600 has filled the gap in lightweight medium-range lidar. The device has a total weight of 2345g and a maximum range of 1000m. It can be mounted on the V10/D20/D500 intelligent drone system for efficient operations. DV-LiDAR600 integrates a full-frame camera module. Using a 28mm focal length aspherical lens can acquire laser data while simultaneously acquiring orthophoto data of high resolution.

D-LiDAR2110&2210 is another series of miniature airborne lidar payloads developed by Foxtech Robot based on its own MTC technology. This series of equipment continues the design concept of Foxtech Robot's micro-airborne lidar payload. It uses limited hardware and high-precision algorithms to create a highly reliable and low-cost engineering tool to provide customers with high-precision and high-quality surveying and mapping results.

From November 8th to November 10th, the first China Surveying and Mapping Geographic Information Technology and Beidou Application Expo concluded successfully at the Zhejiang Deqing International Exhibition Center. This expo is co-sponsored by the China Society of Surveying and Mapping, the China Geographic Information Industry Association, and the China Satellite Navigation and Positioning Association. It has an exhibition area of 20,000 square meters and brings together 148 exhibitors, including the main forum, 38 sub-forums, and a technology and industrial development salon. , "Surveying and Mapping Geographic Information + Beidou" Night and China Surveying and Mapping Geographic Information Technology and Beidou Application Expo and many other activities were unprecedented in scale, attracting tens of thousands of participants.
