On December 23, a grand unveiling ceremony of "Aerial Survey Data Processing Center" and "Geographic Information New Technology R & D and Application Center" was jointly held by Guangdong Water Power Vocational College and Guangzhou Zhixuncheng Geographic Information Technology Co., Ltd. Held a "Surveying and Mapping Artificial Intelligence Symposium."

This meeting has been from all over the country A and B units and other colleges and universities strongly support the presence of nearly 300 people!

Cadastral mapping in such densely populated housing areas as rural cadastral surveys has always taken a large amount of time, effort and cost of surveying and mapping personnel. The production units have always wanted to shorten the construction period and reduce the cost by means of aerial survey. At present, there is no valid approach to achieve this goal.

Guangzhou ZXC Geographic Information Technology Co., Ltd. After a long period of research and put a lot of manpower and resources, and ultimately go through the "oblique photogrammetric production of 5CM Error Line Plan DLG" the technical route, and with Guangdong Institute of Water Resources and Electric Power jointly established a computer room of aerial survey data processing center and formed an excellent application innovation base of "cultivating and improving students' innovative and practical ability" and can provide data production in various fields such as digital city, urban planning and municipal administration Processing services.


Application Case - Rural Cadastral Survey - 1: 500 DLG line drawing

Baiyun District, a village of rural cadastral survey project, the data center using the wind resistance of 7 industrial-grade Hawado rotor tilt photography UAV collected a large number of high-resolution aerial images, combined with high-precision image control point Acquisition, the industry using the United States imported ContextCapture-Center cluster aeroeconomy and modeling, get high-precision real-world three-dimensional model, and then the naked eye based on real three-dimensional model and undistorted original film using Wuhan Skyrim DP-Modeler for efficient acquisition High-precision digital line drawing DLG.

High-precision real-world three-dimensional model




High-precision, high-resolution real 3D models, eaves can be directly corrected, the number of layers can inform the structure



DLG (Residental Stratum), which is not collected by the naked eye in the domestic industry without any external adjustment



The total station field test the entire test area, the housing corner (has been corrected) and obvious points relative to the adjacent control point error in no more than ± 0.05 meters! Meet the requirements of the accuracy of rural cadastral survey mapping project!


The value of this technical route reflects:

1. High precision: plane and elevation accuracy of less than 5CM! And the accuracy of uniform distribution, but also to avoid the problem of surface approximation error;

2. High efficiency of data collection: a total of 35 people completed a total of 1 square kilometers a day (about 20 days); contiguous zone higher production efficiency! Time is money, high efficiency brings high efficiency!

3. The small amount of work in the field: a great reduction in the heat of the outdoor measurement time, but also reduces the field of subsidies, fares and accommodation fees; the industry can be achieved high-precision eaves correction, confirm the number of floors, housing structure The workload of information, field mapping and retesting is very small;

4. Safe and reliable: Hawa UAV belongs to military products, the failure rate is very low, no pressure on the city flight! Without touching the target, can achieve the goal of dangerous targets and environmental data collection;

5. To facilitate internal quality inspection: DLG is based on real-world three-dimensional model collection, quality inspection links in the project can access mapping staff collected what point to confirm whether the acquisition is correct;
      6. Technology upgrading to bring more business: the upgrading of professional and technical strength to bring better corporate image, better able to bring higher quality business and projects!
