GeoVRML is an effort to provide support for representing and visualizing geographic data using standard VRML97 (Virtual Reality Modeling Language). GeoVRML 1.0 includes a Recommended Practice document that makes recommendations on how to extend VRML to support geographic applications. It also includes an open source sample implementation of the new nodes that are described in this document. This work is a product of the GeoVRML Working Group, an official working group of the Web3D Consortium.

Recommended Practice Document

The GeoVRML 1.0 Recommended Practice document details a number of goals for representing geographic data using VRML, describes the various issues associated with these goals, and introduces a number of new nodes that achieve the goals.

The GeoVRML Run-Time

The GeoVRML 1.0 package includes an open source sample implementation of the new nodes that are described in the above document. In order to use these nodes, users must install the GeoVRML 1.0 run-time on their system.

Example Content

This link provides a number of examples of GeoVRML content as a showcase for its capabilities. Note, in order to view any GeoVRML content, you must first download and install the GeoVRML Run-Time (see above).

Open Source Sample Implementation

Developers can obtain the full source code for the GeoVRML 1.0 nodes and associated run-time. These are supplied in the spirit of open source to foster exchange of knowledge and enable the community to further develop these capabilities. You do not need to download this material in order to browse GeoVRML scenes.


This page contains a collection of links to various tools and utilities that support GeoVRML. This includes tools that generate GeoVRML data from other sources as well as tools that perform operations on GeoVRML models themselves.
