The existing three-dimensional GIS software of the webpage end mostly adopts the WebGL technology. WebGL, Web Graphics Library, is a set of JavaScript APIs for rendering interactive two-dimensional and three-dimensional Graphics that can be compatible with any Web browser and does not require any plug-ins. A three-dimensional GIS open source engine developed based on the WebGL technology is known as Cesium. Therefore, many software developers in China develop own webpage-side three-dimensional GIS software based on Cesium.
However, the three-dimensional GIS capability required by development based on WebGL or open source framework Cesium has the advantages of long development time, large code total amount, higher requirement on capability level of developers and higher overall development cost.
And the traditional data loading shows that all operations are on the client side (as shown in fig. 4) no matter the desktop or the Web program. This mechanism results in data being inevitably downloaded locally when it is presented and applied. Under the mechanism, whether the data is maliciously downloaded or not can be judged only by calculating the access amount of a certain IP, and the maliciously downloading is limited. But more or less data goes to the client. And the data in different areas are accessed through multiple IPs, and all the data can still be downloaded to the local, so that data leakage is caused.
