Embodiment Construction

[0043] The embodiment of the present invention provides a GIS information processing method and device, which can effectively solve the problem of unsmooth roaming due to relatively large scene data when the three-dimensional GIS process loads all refined models.

[0044] see figure 1 An embodiment of a GIS information processing method provided by an embodiment of the present invention includes:

[0045] 101. Establish refined scenes based on GIS information;

[0046] In this embodiment, the GIS application system can import real scene information into the refinement process to perform refinement modeling.

[0047] It should be noted that the above real scene information can be changed in real time, and the establishment process of the corresponding refined scene is also a dynamic process, which can change the texture, material and rendering effect of the scene accordingly.

[0048] 102. Cut the refined scene according to the preset cutting rules to obtain several partial s...

Abstract

The invention discloses a GIS information processing method and device. The GIS information processing method and device can effectively solve the problem that when a full refined model is loaded by a three dimensional GIS process, the data of a scene are larger and roaming is not smooth. The method comprises the steps that firstly, a refined scene is built according to GIS information; secondly, the refined scene is cut according to a prearranged cutting rule to acquire a plurality of partial scenes; at last, the partial scenes are loaded to the GIP process, and operations are conducted on the partial scenes by the GIS process. Because only the partial scenes are loaded by the three dimensional GIS process, and the number of the data of the partial scenes is small, the problems that when the full refined model is loaded by the three dimensional GIS process, the data of the scene are large and roaming is not smooth are effectively solved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a GIS information processing method and device. Background technique [0002] Geographic Information System (GIS, Geographic Information System) is a computer system used to collect, store, manage, process, retrieve, analyze and express geographic information data, and is a general technology for analyzing and processing massive geographic data. [0003] Looking at the current situation at home and abroad, the research of 3D GIS has made great progress, focusing on the visual expression of the real world. It has developed from a professional software technology to a very important platform software in the IT field. play an important role in more and more fields. [0004] Although some achievements have been made in the research of 3D GIS visualization technology, further in-depth research is still needed in improving the roaming speed of massive data, improving the reali...
