The British Library, in conjunction with Old Maps Online, the website dedicated to making very old maps available digitally, and blogged about here previously, has announced a new georeferencing project. The site is asking for interested folks to participate in a new round of crowdsourced georeferencing. Using the Georeferencer software in a browser, users assign points on the globe to a map image, tying the map to the correct place on Earth. Georeferenced maps can then be downloaded and used in GIS or other software that can use the geographic information to place the old map where it's supposed to be located in relation to other spatial data.
Anyone can participate in the new georeferencing project at the British Library site. The last georeferencing project was a huge success, and hopefully the same will be true again so that more very old maps can be freely available online with enhanced spatial functionality.
The United States Geological Survey (USGS) and the American Association of State Geologists (AASG) have just re-released the National Geologic Map Database (NGMDB) on Geologic Map Day, 2012. The NGMDB provides ". . . well-documented and standardized geoscience information that can be used to support research, understanding, and decisions on a wide breadth of societal needs," including over 90,000 products from over 600 publishers.
One example of the improvements made to the NGMDB is MapView, which provides, "the systematic, regional mapping of the bedrock and surficial deposits, conducted by Federal, State, Universtiy, and private entities since the 1800's." Find out more about MapView and other updates at the NGMDB site.
OskiCat, the library's catalog, is currently experiencing an indexing problem that makes reliably finding topographic maps difficult. Here's a workaround to help you find maps in the meantime:
From the Quick Search tab, click into the More Searches link:
Select Genre/Form and search for [topographic maps]:
Click the Sort/Limit Results button on the search results page.
Scroll to the bottom, select Words in the SUBJECT and search for [country].
Browse the search results for maps and map sets that may cover your area of interest.
You can find more information about finding maps on the Earth Sciences and Map Library website.
The new acquisitions lists for books and maps on the Earth Sciences and Map Library's homepage are now refreshed nightly with material that is new to the library. Check out the new acquisitions at the library either through the lists on the homepage or via rss.
As always, you can search OskiCat, the online catalog for UC Berkeley libraries, to find books, journals, maps, and data.
Fall semester hours for the Earth Sciences and Map Library begin on Thursday, August 23, 2012.
During semester hours, the library is open Monday - Thursday 9am - 7pm and Friday 9am - 5pm. The library is closed on Saturday and Sunday.
The Circulation Desk closes 15 minutes before the library does. This means no items can be checked out or returned after 6:45pm Monday - Thursday, and 4:45pm on Friday.
The library will be closed for upcoming holidays including:
Monday, September 3 (Labor Day)
Monday, November 12 (Veterans Day)
Hope to see you in the library soon!
