From a somewhat unlikely source, Jalopnik, comes a brief tutorial on reading road maps. While many of us here at the Earth Sciences and Map Library wouldn't consider ourselves "old timers," we apparently have some resources that require skills that may have begun to fall by the wayside with the use of portable gps devices and in-car turn-by-turn navigation. Regardless, there is some interesting information in the post, especially good for those who would like to eek out the last of their summer vacation with a road trip.
The library also has quite a few resources for anyone who might be interested in learning more about map reading and interpretation. Specific subjects range from historic to more specialized, like geologic map interpretation.
Treehugger has an interesting slideshow of 12 subway maps from cities and metropolitan areas around the world. Each slide can be viewed in a smaller thumbnail image or a larger scanned file or digital image. Cartographic commentary, information, and trivia are included with each map. Unfortunately, neither BART nor Muni made the cut. Thanks to Jonathan Crowe at The Map Room for sharing the link.
The Earth Sciences and Map Library has quite a few transit related books and maps available. You can find more information about these resources by searching OskiCat, the online catalog for UC Berkeley Libraries.
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.
