Lenses L.A. Times: David Hockney claims that many famous paintings were traced using optical devices And if I'd gotten around to it, and finished typing up my notes from seeing David Hockney lecture at the L.A. County Museum of Art, I woulda told this story here. Inertia. Ain't it grand? Still, Hockney's notion that lenses were in use up to 500 years ago is compelling. Very compelling.

Science, Freedom of Information and the Military ...and a local story, to boot. Pasadena Star News: Security Concerns delay release of SRTM images.

LA CANADA FLINTRIDGE -- Imagine confidently flying blind through San Francisco's notorious pea soup fog, knowing exactly how high you soar above the ground.

Try a similar trip virtually, touring Afghanistan's arid mountains and Costa Rica's rumbling volcanoes on your home computer.

All of these journeys were possible before the Sept. 11 attacks. Since then, security concerns have delayed the scheduled release of information from the February 2000 Shuttle Radar Topography Mission. Scientists and private companies across the country now anxiously await word from the Department of Defense's National Imagery and Mapping Agency, which controls the release.

Strangely enough... I've been in Bryce looking for elevation data for the Los Angeles area... same stuff as what's illustrated in the picture there in the article, but not as detailed. Hrm. If I get further with it, I may post *my* (not as detailed) image, courtesy of Bryce and the USGS.
