svg-based webgis system and corresponding energy consumption monitoring system

Abstract

The invention provides an SVG (Scalable Vector Graphics) based Web GIS (Web Geographic Information System) system. The system comprises a server and a client, wherein the server further comprises a data persistent layer, an application logic layer and a Web service interface, and the client comprises a browser; the data persistent layer is used for storing space geometrical geographic data, the application logic layer is used for transferring the Shape file format space geometrical geographic data stored in the data persistent layer into the SVG format, and finally forms an SVG map; and the client interacts with the server through the Web service interface, the client sends a request to the server through the Web service interface, and the server sends an SVG map to the client through the Web service interface. The system provided by the invention has the advantages that the system utilizes the advantages such as accuracy, high scalability and small data amount of the SVG, transfers the long-term accumulated geographical information in the traditional GIS system, and enables the information to be displayed in the network terminal for people to develop and use.

Description

technical field [0001] The invention relates to the technical field of internet geographic information system application, in particular to an SVG-based WebGIS system and a corresponding energy consumption monitoring system. Background technique [0002] With the development of Internet technology, Internet Geographic Information System (webGIS) has become the hot spot of Geographic Information System (GIS, Geographic Information System). One of the main development directions of WWW GIS is multivariate data access, which requires spatial data to be open in a distributed network, and any data in a distributed network can be accessed through an exchange format. At present, WebGIS at home and abroad basically uses two kinds of map generation technologies, namely raster graphics technology and vector graphics technology. [0003] Among them, the disadvantage of raster graphics technology is that it is impossible to separate text data and geometric representations, the amount o...

AI Technical Summary

Problems solved by technology

[0007] First: The existing WebGIS data storage structure does not adopt standardized storage rules, making its storage and reading not universal, and the data is not scalable

[0008] Second: Only one data buffer storage is performed on geospatial data, and there is a phenomenon of instant data generation, so the pressure on the server and database will be very high, and blank areas are prone to appear when user services use maps;

[0009] Third: the existing geospatial data has a certain degree of closure
