Abstract

The invention discloses a construction method and system of a three-dimensional GIS platform, and the method comprises the following steps: S1, obtaining platform function demand information and GIS data, and building a technical hierarchical framework; s2, creating functional modules according to the functional requirement information, and analyzing the requirements of the functional modules to decompose each functional module into a plurality of functional sub-modules; s3, compiling logic characteristics of each sub-module by adopting a function analysis method according to the GIS data, anddetermining data flow directions among the sub-modules by adopting a sequence diagram method; and S4, constructing a three-dimensional GIS platform according to the logic characteristics of each sub-module, the data flow direction of each sub-module and the data calling relationship among the sub-modules. According to the technical scheme, optimization processing is carried out on the bottom layer module of the GIS three-dimensional platform system, the loading speed of the GIS platform can be increased, and reusability is higher.

Description

technical field [0001] The present invention relates to the technical field of building a three-dimensional GIS system platform, in particular to a method and system for building a three-dimensional GIS platform. Background technique [0002] Since the 1990s, due to continuous breakthroughs in computer technology and the improvement of GIS-related theories and technologies, GIS has developed rapidly throughout the country. It has achieved remarkable results in massive data storage, processing, expression, display and data sharing technology. At present, the application of GIS has shifted from basic information management and planning to more complex regional development, forecasting and forecasting, and has become an important auxiliary decision-making tool. There are many existing GIS platforms, but for its research and application, there are two situations: one is to use the GIS platform to process user data, such as using big data to display regional information on the G...
