Xianning Municipal Urban-Rural Planning Bureau starts 3D technology training

  XIANNING - In the afternoon of July 11th, the Xianning Municipal Urban-Rural Planning Bureau held the training class of 3D image technology application, preparing for the comprehensive transformation of China Geodetic Coordinate System 2000 (CGCS 2000).

  As an essential part of the planning information construction, the application of 3D image technology will help us to come up with more scientific analysis and assessment on the advantages and disadvantages of a project in terms of spatial form, city color, and the harmonious degree of landscapes, so as to rationally give guidance on the orientation of urban planning and construction, and ultimately provide detailed and comprehensive data support to the “Smart Xianning” construction.

  CGCS2000 is a geocentric coordinate system which is established independently by China and adapts to the developmental trend of modern space technology, featured by 3 dimensional, dynamic and high precision, etc. Currently, what Xianning city adopts is 1980 Xi’an geodetic coordinate system, a reference-ellipsoid-centric, 2 dimensional and static plane coordinate system, which has a great difference between the results calculated from the ellipsoid parameters and those obtained from modern technological methods, in other words, it can’t fulfill the application requirement of high precision geometric information service.

  An official from Xianning Municipal Urban-Rural Planning Bureau said that launching the transformation of CGCS 2000 across-the-board can ensure the integrity and coherence of geographic information resources, and it is able to coincide with the subsequent basic mapping and surveying outcomes coordinate system, which is conducive to the application of surveying achievements, so as to speed up the “Smart Xianning” construction.
