Hebei: Empower real estate registration with real three -dimensional angle

Ji Shi client report (correspondent Bai Weite Zhang Qiannv Sun Yuxia) In recent years, Hebei Province's Third Surveying and Mapping Institute is guided by the application of real three -dimensional service natural resources management. As an electronic sand table, the picture is fully combined with the tilt photography, three -dimensional models and real estate data. Through the secondary development of the system, the information query, auxiliary issuance, and statistical analysis of real estate management in the three -dimensional scenario are realized to help the science of the natural resource management department science Decisions are at the forefront of the same industry in the country.

At present, the system has completed the main functional development and testing work. It is conducting the system trial operation and testing and improvement. Information and building attribute information, retrieve the corresponding non -motionless units, quickly locate the position of the model, and related special data statistics and analysis according to the inquiry conditions such as right holders, locations, and non -mortal unit numbers.

The established three -dimensional management system has transplanted two -dimensional real estate information. In the three -dimensional model, the three -dimensionalization of real estate management has been achieved, which makes up for some shortcomings of traditional real estate registration:

Three -dimensional natural buildings are generated by "high" and three -dimensional household three -dimensional models of the two -dimensional natural building. The problem of distribution;

Construct a three -dimensional natural building data and layered divided household three -dimensional model

When adding a new registration business, the real -life three -dimensional data can be superimposed with historical data and the topology restructuring. This update method can achieve rapid update of incremental increase based on the original two -dimensional historical data;

Real -view 3D data and two -dimensional vector data sets to realize the linked query positioning and attribute hanging of two -dimensional and three -dimensional independent unit data. It solves the problem of difficulty in registering information positioning. The trouble of block information.

Establish a database, superimposed high -resolution images to achieve real estate information query

The person in charge of the Hebei Provincial Third Surveying and Mapping Institute said that the system has expanded the application of 3D in the application of real estate in real estate applications, and improves the accuracy of business management at the space level. In the next step, the experiment is loaded with real estate registration data and real three -dimensional data to related business platforms. It optimizes the system in the trial operation, and promptly solve practical problems in natural resource management. Finally, the three -dimensional real estate management system and promotion application work.
