A platform for civil engineering geographic design based on soa architecture

Abstract

The invention discloses a civil engineering geography design platform based on SOA architecture. The civil engineering geography design platform comprises an SOA data bus, a CAD module, a geographic information system module, a data storage module and a data scheduling engine module. The CAD module and the geographic information system module are connected to the SOA data bus. Geographic information system space model data and CAD space model data are stored in the data storage module and disintegrated into geometric primitive data namely point, line or surface data. Each point datum, each line datum or each surface datum after disintegration is associated with the space model data before disintegration through data structures. The data storage module is communicated with the SOA data bus through a point data interfaces, a line data interface and a surface data interface. The data scheduling engine module is connected to the SOA data bus. The platform has the advantages that geographic environment factors are combined with a design process, geometric primitive is used as intermediate data bridge, seamless integration of CAD data and GIS data is achieved, and fast scheduling and visualization of massive data is researched on the basis of the integration.

Description

technical field [0001] The invention belongs to the field of civil engineering design, in particular to a civil engineering geographic design platform based on SOA framework. Background technique [0002] The data used by the two disciplines of CAD (Computer Aided Cartography) and GIS (Geographic Information System) can be summarized as flat or three-dimensional spatial data from a mathematical perspective. However, the focus of the research of these two disciplines is different. The content of CAD research mainly lies in refined mapping, and the content of GIS research mainly lies in the management, analysis and application of spatial data. In some fields, especially in the field of civil engineering, it is often necessary to use the knowledge of these two disciplines together; in order to solve these interdisciplinary engineering problems, people invented a new discipline "geographical design", which has become the current GIS and The hottest research topic in the field o...

Problems solved by technology

The advantage is that it solves the problem of large server requests; the disadvantage is that a large memory data buffer space is required to save the used data

The third is the model simplification method. According to the importance of the points in the model, it is usually sorted according to the degree of influence on the volume, and a progressive data flow is established, and then dynamically loaded through the network. The disadvantage is that the algorithm for automatic calculation of vertex importance is complicated. It is easy to cause model distortion
