Introduction:What is BIM on GIS project?
3Introduction to BIM on GIS Open Platform
BIM data GIS data
Objects of Buildings Objects on the Earth
Walls, Pillars, Floors, Windows, Doors, etc. Roads, Buildings, Mountains, Trees, etc.
Usually created by HumanUsually generated via surveying(and
processing)
.RVT, .IFC, and so on .SHAPE, .GEOTIFF, and so on
BIM data vs. GIS data
There’re basically and originally differences between BIM data and GIS data.
4Introduction to BIM on GIS Open Platform
BIM data GIS data
BIM data vs. GIS data
BIM data and GIS data are xenogeneic data.

IFCG3D
* Industry Foundation Classes (IFC) data model is intended to describe building and construction industry data. It is a platform neutral, open file format specification that is not controlled by a single vendor or group of vendors. It is an object-based file format with a data model developed by buildingSMART (formerly the International Alliance for Interoperability, IAI) to facilitate interoperability in the architecture, engineering and construction (AEC) industry, and is a commonly used collaboration format in Building information modeling (BIM) based projects
Service Model of IFC for Interoperability
Service Model: IFC conversion format for BIM/GIS interoperability G3D is designed for rapid display of big size IFC data based on GIS Characteristics of G3D
Including IFC geometry and property information Relative coordinate + Georeference information(Latitude, Longitude, Altitude,
Direction, Etc.) LOD and spatial indexing information for rapid display Geometry information based on file system Property information based on database (ongoing)

Simplification, Hierarchical, and Data Streaming are required for rapid display.
12Introduction to BIM on GIS Open Platform
Technology for Rapid Display
G3D format G3D stands for Gaia3D Defined and developed by Gaia3D For rapid processing of BIM data for visualization Adopts block/reference concept: Generated geometries is defined as blocks
and all objects referring to blocks is defined as reference.

World Wind Java for 3D GIS World Wind is an open-source (released under the NOSA license) virtual globe developed by NASA and the open source community for use on personal computers. Old versions relied on .NET Framework, which only ran primarily on Microsoft Windows. The more recent Java version, World Wind Java, is cross platform. World Wind Java is a Software Development Kit (SDK) which is aimed at developers and is not a standalone virtual globe application in the style of Google Earth.
