A webgis middleware supporting multiple industries

Abstract

The invention discloses a WebGIS middleware supporting multiple industries, which includes a GIS base layer, a GIS extension layer and a GIS interface layer from top to bottom, and each layer provides services to the upper layer, and uses the Serve. The GIS base layer realizes its own map service and initialization through the acquisition of services from different GIS platforms. The GIS extension layer includes the internal implementation of all GIS operations. The purpose is to add information point processing and layer operations on the map. GIS interface The layer directly provides application programming interface API for WebGIS application to realize the information service of GIS data. The present invention provides a reusable and interface-standard WebGIS middleware not limited to the GIS platform, which can quickly complete the development of map access and initialization when the middleware is developed for the first time; when the middleware is maintained or rewritten It is only necessary to change the implementation strategy for the new platform without changing the structure and interface specification of the middleware.

Description

technical field [0001] The invention belongs to the technical field of WebGIS middleware, and in particular relates to a WebGIS middleware supporting multiple industries. Background technique [0002] Geographic Information System (GIS) is a specific technical system that collects, stores, manages, calculates, and analyzes spatial information and then presents it in the form of graphics and images. In the past 30 years, GIS technology has achieved amazing development, widely used in resource survey, environmental assessment, disaster prediction, land management, urban planning, post and telecommunications, transportation, military public security, water conservancy and electricity, public facility management, agriculture and forestry Almost all fields such as animal husbandry, statistics, business finance, etc. [0003] Since the 21st century, the rapid popularization of Internet technology has provided a new direction and impetus for the development of GIS. The combinatio...

Problems solved by technology

[0006] However, most of the existing WebGIS middleware is a network structure, covering a wide range of functions, but the functional interfaces used by the application systems of different industries are less than 50%, and there is no interface directly corresponding to the relevant business of each industry It can be directly called by the application system, but it still requires complex development work when applied to different systems, and the workload of transplantation is still very large
