Problems solved by technology
[0006] This way of displaying data is difficult to satisfy good data transmission and user experience
First of all, the timing refresh of the front-end of the GIS platform cannot accurately know the change time of the back-end data, so the time of the data channel is wasted, and the back-end data of the GIS platform cannot be notified to the front-end of the GIS platform in real time after the change; secondly, due to data lag and Constant requests for refresh cause the data display on the front end of the GIS platform to fail to display the data function well

The invention relates to a power grid resource dynamic real-time GIS rendering algorithm based on a GIS platform, and the algorithm comprises the following steps: compiling and deploying a GIS power grid resource platform rear-end server code; compiling a GIS rendering algorithm of a GIS platform back-end server end; calling programming and deployment of a layer algorithm program; compiling and deploying a GIS map rendering program at the rear end of the GIS platform; pushing the rendering layer result to the GIS platform front end by the GIS platform back end; and loading related informationGIS rendering data at the front end of the GIS platform for display. Various kinds of resource information of power production and operation can be timely, accurately and comprehensively acquired, meanwhile, a guarantee can be provided for safe and efficient operation of a power grid, and more comprehensive and perfect services are provided for users. A GIS platform front-end display interface does not need manual operation, a power grid resource GIS rendering interface is automatically entered, and the latest data pushed by the GIS platform is subjected to default rendering effect display atthe GIS platform front end.
Description
[0001] (1) Technical field [0002] The invention relates to GIS technology, in particular to a dynamic real-time GIS rendering algorithm for power grid resources based on a GIS platform, which relates to an application method of a realistic graphic rendering algorithm. [0003] (2) Background technology [0004] Map rendering in GIS is mainly to convert spatial data into map images and display them through computer simulation. A high-quality map needs to accurately and vividly represent the location, shape, and quality level of geographic elements, which involves the setting of the spatial coordinate system and The expression of map symbols is a very basic and very important functional module in the GIS system. [0005] In this technology, it mainly relies on the regular refresh of the front end of the GIS platform, and sends the layer request parameters and function request parameters to the server; the server performs logical operations and processing on the request, and obt...
