Embodiment 1

[0036] Embodiment 1: a method for publishing WebGIS based on IFC, the specific implementation steps are:

[0037] 1) Server deployment, including the following operations:

[0038] Web server deployment: deploy Tomcat server and jdk1.8;

[0039] BIMServer server deployment: deploy the war package of BIMServer1.5.117 version to the Tomcat server;

[0040] BIMServer plug-in installation: enter the BIMServer management page, add management information in turn, and select IFCOpenShell and Three.js plug-ins to install;

[0041] 2) Extended IFC data export: Based on the existing 812 classes of IFC4, the IFC data is extended according to entity types, and the expanded entity types are included in the IFC standard sharing layer and IFC standard field layer to meet the standardized management of engineering construction Requirements: Start Autodesk Revit 2019, modify the exportlayers-ifc-IAI in the Revit export option, and map the entity to the extended IFC entity description; recomp...

Abstract

The invention relates to the technical field of geographic space information systems, and specifically relates to a WebGIS publishing method based on IFC extended data. The WebGIS publishing method achieves fusion of BIM and GIS through the steps of server deployment, extended IFC data exporting, extended IFC data analyzing, extended IFC file analyzing and WebGIS publishing, and can guarantee thefusion precision and the fusion efficiency.

Description

technical field [0001] The invention relates to the technical field of geographic space information systems, in particular to a WebGIS publishing method based on IFC extended data. Background technique [0002] With the continuous improvement of the informatization level of engineering construction in our country, more and more engineering projects have begun to use visual means for information management. As an open international standard for the expression and exchange of building product data, IFC data supports data exchange and sharing throughout the life cycle of buildings. It supports the data exchange between various application systems in the horizontal direction, and solves the data management of the whole life cycle of the building in the vertical direction. IFC format is a standard open data expression and storage method, which has been widely used and supported in the global AEC industry. [0003] IFC has many analysis engines. The BIM Server software is an ope...
