SIGGRAPH

Special Projects

The Carto Project is an ACM SIGGRAPH Special Project that explores how viewpoints and techniques from the computer graphics community can be effectively applied to cartographic and spatial data sets. The "Carto Project" is in collaboration with the International Cartographic Association's (ICA) Commission on Visualization and the GeoVRML Working Group of the Web 3D Consortium. The project seeks viewpoints from the computer graphics community on technology (including hardware and software) and techniques that will impact and can be applied to cartographic visualization.

Our SIGGRAPH 2007 Carto BOF meeting is scheduled for Tuesday, August 7th, 12:30 - 2:30 PM, in Room 29B of the San Diego Convention Center (during SIGGRAPH 2007). See: (SIGGRAPH 2007 Birds of a Feather Sessions). In addition to our one hour technical update session, we will also feature a session on Google Earth mashups and X3D Earth applications.

Our SIGGRAPH 2006 Carto BOF Meeting was held Wednesday, August 2, 2006, 2:00 - 3:00 PM, in Room 203 of the Boston Convention and Exhibition Center.

The summary notes of our this session can be found at: (http://www.siggraph.org/~rhyne/carto/carto06sum.html).

Our project began in 1996. During the 1997 year, we conducted a survey on cartographic and geographic visualization. These and other issues were discussed at an ACM SIGGRAPH 97 Birds of a Feather session on August 6, 1997.

In 1998, we have served as a focal point for information gathering on:

-- standardization of cartographic data representation among and between various computer graphics systems.

-- establishment of data standards for computer graphics and cartographic applications

-- tracking of trends in the adoption of VRML by the computer graphics and cartographic communities.

These efforts are ongoing activities of the ACM SIGGRAPH Carto Project.

At SIGGRAPH 98, we held our 1998 Carto BOF meeting. At the meeting, Alan MacEachren reported on the research agenda of the International Cartographic Associations's Commission on Visualization. Martin Reddy demonstrated his newly developed GeoVRML Nodes ( VisiblityInline and QuadLOD nodes) for handling large terrain datasets in VMRL. Don Brutzman also showed a GeoVRML application which used Reddy's GeoVRML nodes. The GeoVRML Working Group of the VRML Consortium also released its GeoVRML Request for Comment document in honor of the 1998 Carto BOF meeting.

In 1999, members of the Carto Project presented their viewpoints on integrating cartography and computer graphics. For VRML 99, Jason Dykes, Kate Moore, and David Fairbairn authored a paper on "From Chernoff to Imhof and Beyond: VRML & Cartography", (http://www.geog.le.ac.uk/jad7/VRML99/). In the March/April 1999 issue of IEEE Computer Graphics and Applications, Martin Reddy, Yvan Leclerc, Lee Iverson, and Nat Bletter published a paper on "TerraVision II: Visualizing Massive Terrain Databases in VRML", (http://www.computer.org/cga/cg1999/g2030abs.htm). A PDF copy of this article can be found at: (http://www.ai.sri.com/~reddy/pubs/CGAVRML/).

The June 1999 issue of the International Journal of Geographical Information Sciences was devoted to visualization of spatial data. It was guest edited by the Chair (Alan MacEachren) and Co-Chair ( Menno-Jan Kraak) of the International Cartographic Association's Commission on Visualization. A Web Supplement of this special issue is located at: (http://www.geovista.psu.edu/sites/icavis/publications/IJGIS99.html).

In 2000, open source code for GeoVRML 1.0 became available, (http://www.geovrml.org). "Under the Hood of GeoVRML 1.0", by Martin Reddy, Lee Iverson, and Yvan G. Leclerc, was selected as the Web3D-VRML 2000 Best paper and was presented at the Web3D-VRML 2000 Symposium in February 2000. See: (http://www.ai.sri.com/~reddy/pubs/pdf/vrml2000.pdf).

In late 2000/ early 2001, the International Cartographic Association's Commission on Visualization and Virtual Reality published a geovisualization research agenda in a Special Issue of Cartography and Geographic Information. See: (http://www.geovista.psu.edu/icavis/agenda/index.html). In 2001, GeoVRML was incorporated into the Environmental Systems Research Institute (ESRI)'s Arc products and SRI International has produced an OpenGIS Consoritum Web Mapping Server (WMS) that can output GeoVRML content. In 2002 and 2003, work continued on incorporating GeoVRML into the X3D standard under development by the Web3D Consortium.

In 2004, Theresa-Marie Rhyne and Alan MacEachren offerred a course on "Visualizing Geospatial Data" at SIGGRAPH 2004 that featured ACM SIGGRAPH Carto Project and the ICA Commission on Visualization and Virtual Reality efforts. See: (http://www.siggraph.org/s2004/conference/courses/30.php?pageID=conference).

In 2006, Theresa-Marie Rhyne, Alan MacEachren and Jason Dykes guest co-edited a theme issue on GeoVisualization for the July/August 2006 issue of IEEE Computer Graphics and Applications Magazine. See: (http://csdl2.computer.org/comp/mags/cg/2006/04/g4020.pdf)
