This page contains links to a number of organizations and groups that are interested in standardizing or supporting 3D geographic visualization. Many of these are complimentary to the work being performed in the GeoVRML working group. Please e-mail the maintainers (below) if you know of a group that should be included in this list.

The Equip@ge 3D Information Systems
The GeoVRML.com web site is run by Eric Maranne and contains some wonderful terrain and urban simulations done using VRML and GeoVRML, among other technologies. Eric has performed a number of military and commercial contracts involving terrain visualization and his site includes software downloads, a gallery of previous work, and a description of services. Although bearing a similar name, Eric's site is not directly related to the Web3D GeoVRML working group and is not a commercial effort based solely upon Web3D GeoVRML technologies. It does have some great content however.

The Virtual Terrain Project
The goal of VTP is to foster the creation of tools for easily constructing any part of the real world in interactive, 3D digital form. This web site has a host of useful resources relating to the 3D visualization of terrain.

The Geography Network
The Geography Network is a global community of data providers who are committed to making geographic content available. This content is published from many sites around the world, providing you immediate access to the latest maps, data, and related services. This portal to the Geography Network enables you to discover this content and share your own.

The OpenGIS Consortium
The OGC is a not-for-profit membership organization founded in 1994 to address the lack of interoperability among systems that process georeferenced data. Of particular interest to GeoVRML members is the OGC's Web Mapping Technology Testbed.

The Digital Earth Initiative
Digital Earth will be a virtual representation of our planet that enables a person to explore and interact with the vast amounts of natural and cultural information gathered about the Earth. A number of government, industry, and academic groups are collaborating on the development of Digital Earth.

The Synthetic Environment Data Representation & Interchange Specification is a project of the US Defense Modeling and Simulation Office (DMSO) to standardize the data format and some of the tools used for managing simulation data. When the military says simulation, they generally mean training and rehearsal for real-world missions using real-world data. Thus georeferencing of remote sensing data and of other intelligence data is critical for maintaining versimilitude. Moreover, unlike many other projects of this kind they are interested in speed, and are making their code publicly available.

The SIGGRAPH Carto Project:
The Carto Project is an ongoing outreach initiative of ACM SIGGRAPH to explore how viewpoints and techniques from the computer graphics community can be effectively applied to cartographic and spatial data sets.

The GeoTIFF project is an effort by a large number (~160) of GIS companies to standardize a means of georeferencing and managing geocoded (what does that mean?) raster imagery using the TIFF image file format.

The Distributed Interactive Simulation (DIS) Protocol is used to communicate state information (such as position, orientation, velocities and accelerations) among multiple entities participating in a shared network environment. Of course in real simulation environments this information must often be georeferenced. The DIS-Java-VRML Working Group is another working group of the VRML Consortium which is writing software and standardizing an API for integrating DIS data into VRML worlds using Java.
