GeoWeb 2008 conference hosts student contest.
By Kenneth Wong
In Dallas, Texas, Bryan Chastain, a Ph.D. student at the University of Texas, is building a Web-based mapping application that lets high school football teams select neutral sites for playoff games. About 1,200 miles north, in Toronto, Ontario, Ryerson University student Eric Chang is working on a collaboration platform that lets people in different locations share the same GIS application. In June, Chastain and Chang's programs, along with dozens of others, will be forwarded to a committee of GIS industry leaders as entries for a student contest at the GeoWeb 2008 Conference (July 21-25, Vancouver, BC, Canada). If they both make it to the conference, Chastain and Chang might actually meet, confirming the tagline for the conference: "Everything is connected."
Apparently, finding neutral ground for a football playoff takes quite a bit of wrangling. Chastain, who is as much a fan of the game as he is of geospatial technologies, explained, "Coaches from the competing teams would come together to pick a neutral site. Ideally, they won't want the venue to be advantageous to one team or another. It should be the middle ground, roughly equal distance from both schools. It shouldn't take too much driving time to get there for either side."
The size of the teams is also a consideration. Depending on the number of students enrolled in a semester year, a Texas school falls somewhere within the official 1A (smallest) to 6A (largest) rating system. A six-player team on the lower end of the scale, for example, would typically play in an 80 x 40 yard field; an 11-player team generally requires a 100 x 54 yard field.
"A 5A-rated team would need a standard playoff stadium, whereas a 1A team can just play in a high school stadium," Chastain observed. Read more »

Description Key Sets and Point Styles
By Phillip Zimmerman
In the continuing discussion of styles, points are the first stop in an in-depth look at styles. Point styles are simple, but their use in any one project can be complex. With the emergence of GIS, point observations have become more than mere point number, elevation, and description. Sometimes additional attributes need identification along with a point's coordinates. These attributes can be collected as parameters or user-defined attributes. Points are also a project's bookends; they describe the existing conditions and define the future location of important design elements.
Civil 3D uses point styles to represent observed existing feature coordinates or critical design points. Whether the point styles represent observed or design coordinates, their coding should be consistent from project to project. Consistent names make the assignment of styles and creation of point groups a simple decision-making process. Read more »
