At the end of last month, the Oregon Department of Geology and Mineral Industries (DOGAMI) issued this press release describing their new online interface for their statewide digital geologic map. The online version only covers the eastern portion of the state at the present time. But the interface is not too shabby with the ability to view conventional stratigraphy information, rock properties layers or general rock type. Available overlays include faults, highways, formation boundaries, cities/towns and USGS quad grids. You can also add a shaded relief map or topographic map base map or combine them both. And a feature I wish was more common in some of these online interfaces, they have the ability to export images when you get the view you want. It appears that you can do it at resolutions up to 1200 ppi.
The O’Reilly Where 2.0 conference just wrapped up last week in Burlingame, CA. It is a big deal for developers, geographers, GIS developers, GPS equipment manufacturers and anyone else interested in location web services, GIS, mashups, and the so-called Geoweb. There were two presentations by some high profile players that may be of interest to the readers of GeoPrac.net. I have video versions of both after the break.
First, a presentation titled "State of the GeoWeb" given by Google Earth and Maps Director, John Hanke with some help from Jack Dangemond of ESRI. I think it gives you some interesting insights into the direction things are headed, particularly with some of the upcoming releases of ESRI GIS software and the interplay between location data that people have been producing for some time now and new ways of tapping into it using the web. Kind of a long presentation at around 30 minutes.
Second, Geoff Zeiss of Autodesk, Inc. (makers of AutoCad etc.) gives a presentation titled "Convergence of Architectural and Engineering Design and Location Technology". It deals with bridging the information created by different disciplines such as engineers, architects, trades and contractors into something more productive and usable using techniques such as 3D visualization and simulation. Length is approximately 15 minutes.
Geology.com pointed out a very nice PDF version of a Power Point presentation by the North Carolina Geologic Survey on their landslide hazard mapping efforts in western North Carolina. The presentation was dated August 1 of last year. The NCGS also has their landslide mapping products available for download, and those so inclined can download the GIS data sets as well.
