Problems solved by technology
The interactive realistic visualization capability and complex spatial data analysis capability of 3D Digital Earth’s massive data have high requirements on the software and hardware environment of the client computer. In order to obtain a better user experience, some portable devices such as netbooks, mobile phones, tablet computers, etc. do not run smoothly or normally.
However, the current mainstream desktop virtualization technology is difficult to meet the needs of customers in terms of 3D graphics applications, which also makes the use of 3D digital earth on mobile devices a bottleneck problem

Embodiment Construction
[0031] As mentioned above, the purpose of the present invention is to solve the problem that the 3D Digital Earth application program in the prior art has high requirements on the configuration performance of the client device, and proposes a 3D Digital Earth system that supports desktop virtualization applications. The rendering of geographic data is placed on the server side of the virtual machine, and the client side of the virtual machine receives the rendering results and can interact and control them in real time, so that the problem of large data transmission in Digital Earth applications is simplified to the problem of image transmission. Users access the virtual desktop through the client device. The application program obtains the image information of the 3D digital earth, which eliminates the limitation on the computing power and storage capacity of the client device.
[0032] The present invention will be further described below with reference to the accompanying dr...

The invention discloses a construction method for a three-dimensional digital globe. The method includes the steps that S101, geographic data are collected, processed and stored, and the processed geographic data are issued through http services or web services; S102, the http services or the web services of the geographic data are integrated, three-dimensional visualization and virtualization are performed on the geographic data, and a three-dimensional digital globe application program is formed; virtualization is performed on three-dimensional rendering capacity, so that a GPU of the three-dimensional digital globe is rendered in the virtualization environment in an acceleration mode in real time; S103, graphic information of the three-dimensional digital globe is obtained by the utilization of the three-dimensional digital globe application program so that the three-dimensional digital globe can be displayed. The invention further provides a three-dimensional digital globe system corresponding to the method. The transmission problem of the mass data applied to the digital globe is simplified to be a picture transmission problem, so that limiting on the calculation capacity and storage capacity of client side equipment is eliminated.
Description
technical field [0001] The invention relates to the technical field of three-dimensional geographic information, in particular to a method for constructing a three-dimensional digital earth supporting desktop virtualization applications and a corresponding three-dimensional digital earth system. Background technique [0002] The 3D digital earth is based on the traditional geographic information system technology, and has been widely used in digital cities, digital oceans, navigation and other fields with the characteristics of real 3D scene virtual reality, intuitive, real, visual and efficient. The visualization function of 3D Digital Earth is one of the important functions of Digital Earth. It relies on a large amount of accurate data to provide more abundant and realistic information, so that various users can make accurate and rapid spatial decisions based on their own relevant experience and understanding. . The interactive realistic visualization capability and compl...
