3D GIS for creating, editing, storing and visualizing 3D geographic features and 3D geographic objects using XML and method thereof

摘要

The present invention aims to use (eXtended Markup Language) XML provides creates a three-dimensional geographic features and 3D geographic object, which is the key feature of the 3D GIS, editing, storage and visualization systems and methods that can be there is.; According to the invention, the newly generated three-dimensional geographical features or, edit an existing three-dimensional geographic feature, the three-dimensional geographical feature authoring tool for creating a DTD (Document type Definition) file of XML (3D Geographic Feature Authoring Tool); The 3D with reference to the XML DTD file generated by geographic feature authoring tool, the three-dimensional geographical create an object new or edit an existing three-dimensional geographic object by the three-dimensional geographical object authoring tools stored in an XML file (3D Geographic Object Authoring Tool); And the three-dimensional geographic feature authoring tool XML DTD file created by and 3D geographic object browser to visualize the three-dimensional geographic object reads the XML files generated by the three-dimensional geographic object authoring tools (3D Geographic Object Browser ) a three-dimensional geographical information system, characterized in that formed is provided, including.
