Digital map indexes at EART

Digital map indexes title image

Are you working on a specific place in another country? Interested in finding out if the library has topographic maps of Peru, China, and the former Soviet Union? Would you like to see what map sheets are held by the library without having to leave your office or house?

The Earth Sciences and Map Library has recently digitized nearly all of the indexes for map sets in the library and placed them online. Users can browse the list or use the "Find" functionality in their browser to find map sets for their area of interest.

The indexes can be sorted by area and call number by clicking on the column headings. In the future, each map set will be linked to its corresponding catalog record from the page.

Currently, this list does not include the Army Map Service (AMS) index maps which can be found on a separate page.

Animated map projections on YouTube


Here's an interesting animation by Jack van Wijk of the Eindhoven University of Technology that depicts various strategies for projecting the globe on a two dimensional surface. Some of these projections are well known while others are a bit more experimental.

You can find out more about the animation and the Unfolding the Earth project, including the names of the projections, on the project's site. Professor van Wijk has published a paper in The Cartographic Journal about Unfolding the Earth.

Thanks to Kay Guildner and Maps-L for the link.

Berkeley Seismological Lab Lawson Lecture April 14, 2009

BSL logo

Chris Poland
of Degenkolb Engineers will give the annual Lawson Lecture on Tuesday, April 14 at 6pm in Sibley Auditorium at the Bechtel Engineering Center on the UC Berkeley campus.

This year's lecture, "Building Resilient Communities: Fresh Challenges for Earthquake
Professionals" will present the San Francisco Planning and Urban Research
Association's (SPUR) Resilient City Initiative.

From the BSL Lawson Lecture site: "Healthy communities grow by leveraging intellectual capital to drive economic development while protecting cultural heritage. In the San Francisco Bay Area, as in other regions where earthquakes occur, success depends in part on the ability to rebound from major earthquakes. But action plans for reducing losses have stalled. Chris Poland will present the San Francisco Planning and Urban Research Association's (SPUR) Resilient City Initiative. This Initiative is an effort to avoid post-Katrina-type problems by defining the seismic hazards and response performance goals for San Francisco in terms that everyone can understand. SPUR's path and plans will improve San Francisco's ability to recover and are a guide for other cities preparing to cope with disasters."

You can find a list of past Lawson Lectures, from 2003
on, many with links to presentation material and a webcast of the
lecture itself, on the BSL site.

Rapid disappearance of Antarctica's ice shelves

The USGS has released a report that notes Antarctica's glaciers are melting due to climate change at a quicker pace than previously known. The study documents, for the first time, that the Wordie Ice Shelf has disappeared and that the northern end of the Larsen Ice Shelf no longer exists. An area three times the size of the state of Rhode Island has disappeared from the Larsen Ice Shelf since 1986.

From the USGS press release: "Using historical and recent satellite imagery, aerial photography and other data, as well as the newest mapping techniques, the USGS study released today maps recent glacier retreat along Antarctica?s Larsen and Wordie Ice Shelves. It represents is just one map of several upcoming studies of Antarctica's glaciers."

More information is available in the USGS Geologic Investigations Series Maps I-2600 Coastal-Change and Glaciological Maps of Antarctica and I-2600-B, Coastal-Change and Glaciological Map of the Larsen Ice Shelf Area, Antarctica: 1940?2005.
