The main attraction at the not-yet-open National Museum of Surveying in downtown Springfield, a high-tech video system called “Science on a Sphere,” is up and running.
 
At the heart of “Sphere” is a large plastic globe representing the earth that is suspended a few feet off the floor by wires. On it, four high-speed cameras project images of the atmosphere, oceans and landmasses. The sphere doesn’t move, but the cameras can create the illusion that it is rotating on its axis.
 
“It’s even better than I thought,” Bob Church, treasurer of the museum, said after the equipment had been installed last week. “I’ve only seen it on the NOAA (National Oceanic and Atmospheric Administration) Web site. Seeing it live, it’s just amazing what technology can do.”
