Example Embodiment

[0026] Example: such as figure 1 As shown, the GIS-based method for three-dimensional display of multi-source data front-end includes the following steps:

[0027] (1) Overlay display of GIS multi-source data: Divide GIS multi-source data, and use different methods to load different types of GIS multi-source data according to the results of the division to integrate three-dimensional display on the front end, and perform element editing on the element data. , Collect and update military standard elements and traffic labeling marking elements, and directly load them on the front end to integrate three-dimensional display;

[0028] (2) Process the data: then perform style management and rendering or / and spatial query and measurement analysis or / and statistical analysis on the data integrated in the front-end 3D display in step (1). The medium style management and rendering in the step (2) includes expression-based style labeling, single element rendering, and rule-based element rend

Abstract

The invention provides a GIS-based multi-source data front-end three-dimensional display method, which specifically comprises the following steps: (1) GIS multi-source data superposition display: dividing GIS multi-source data, and loading different types of GIS multi-source data at the front end in different modes according to a division result to perform integrated three-dimensional display; carrying out element editing on the element data, collecting and updating military standard elements and traffic marking and marking elements, and directly loading the military standard elements and thetraffic marking and marking elements to a front end for integrated three-dimensional display; and (2) processing the data: performing style management and rendering or/and spatial query and measurement analysis or/and statistical analysis on the data integrated with three-dimensional display at the front end in the step (1). Three-dimensional display is carried out at the front end in different modes, and a user can directly carry out style management and statistical analysis on the data at the front end, so that the visualization effect of the multi-source data is better, and the performanceof the data is more sufficient; and convenience is brought to the user and the user experience is improved.
