The American Association of Petroleum Geologists (AAPG) has listings for their upcoming educational opportunities on their calendar site. The opportunities include: Field Seminars, Short Courses, Online Courses, and the semiannual Education Conference.
Users can also browse by date: weekly, monthly, or yearly. The calendar page also provides a list view of all AAPG-sponsored opportunities for professional development and education.
Open Street Map is "an editable map of the whole world, which is being built largely from scratch using GPS traces, and released with an open content license." The map is created primarily from gps data posted by users who do field surveys in their areas and use wiki-style collaborative software to create the map. Yahoo! aerial imagery is also a source the project uses to derive mapping data.
A related source of geospatial data is the Public Geospatial Data Project. If you're looking for free gis data, the Public Geospatial Data Project is a valuable clearinghouse. The project's goals include:
NASA and the Japanese Ministry of Economy, Trade, and Industry (METI) have recently released the ASTER Global Digital Elevation Model (GDEM), the most complete topographic map of Earth to date. From the project's site: "The GDEM was created by stereo-correlating the 1.3 million scene ASTER VNIR archive, covering the Earth?s land surface between 83N and 83S latitudes. The GDEM is produced with 30 meter postings, and is formatted in 1 x 1 degree tiles as GeoTIFF files. Each GDEM file is accompanied by a Quality Assessment file, either giving the number of ASTER scenes used to calculate a pixel?s value, or indicating the source of external DEM data used to fill the ASTER voids."
Examples of the imagery are available on the NASA ASTER imagery site.
Users can also use the Warehouse Inventory Search Tool (WIST) to find related remote sensing and other earth science data provided by NASA.
OskiCat, the new UC Berkeley library catalog, is tentatively scheduled to go
live on Wednesday, June 24. It will replace both Pathfinder and GLADIS.
A couple disruptions resulting from the migration:
If all goes well, OskiCat will launch and circulation services will be available as normal on Wednesday, June 24.

The United States Geographic Survey (USGS) has quietly launched the Digital Map--beta, a "a new kind of georeferenced map that is a synthesis and evolution of USGS's legacy digital map data files, the Digital Raster Graphics (DRG)." According to Adena Schutzberg at the All Points Blog, the beta was released on May 8, 2009.
From the site, "The initial version of "Digital Maps ? Beta" includes orthoimagery plus roads and geographic names in the traditional 7.5 minute quadrangle format. The "Digital Map - Beta" is easily accessible, has reasonable file sizes and a common format with embedded tools, and theme-based layers."
A quick start guide is available in pdf format.
While the site is still in beta, there may be some variability in its functioning, but this is a fantastic step toward presenting USGS mapping online.
