Scalable 3D GIS Environment Managed by 3D-XML Based Modeling
Nowadays,the namely 3D GIS technologies become a key factor in establishing and maintaining large-scale 3D geoinformation services.However,with the rapidly increasing size and complexity of the 3D models being acquired,a pressing needed for suitable data management solutions has become apparent.This paper outlines that storage and exchange of geospatial data between databases and different front ends like 3D models,GIS or internet browsers require a standardized format which is capable to represent instances of 3D GIS models,to minimize loss of information during data transfer and to reduce interface development efforts.After a review of previous methods for spatial 3D data management,a universal lightweight XML-based format for quick and easy sharing of 3D GIS data is presented.3D data management based on XML is a solution meeting the requirements as stated,which can provide an efficient means for opening a new standard way to create an arbitrary data structure and share it over the Internet.To manage reality-based 3D models,this paper uses 3DXML produced by Dassault Systemes.3DXML uses opening XML schemas to communicate product geometry,structure and graphical display properties.It can be read,written and enriched by standard tools;and allows users to add extensions based on their own specific requirements.The paper concludes with the presentation of projects from application areas which will benefit from the functionality presented above.
