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.
Another busy month for ASTM with 66 new, revised or otherwise updated standards related to geotechnical and geological engineering (although not as busy as last month). A couple that caught my eye include brand new standards for geospatial data requirements related to abandoned mines, a new standard for sampling of EPS or geofoam, updated standards for mortar and cement, flexural strength of concrete, LA Abrasion test for aggregates, acceptance testing of geosynthetic clay liners, electrical methods for leak detection of geomembranes with earth cover and classification of soils and soil-aggregate mixtures for highway construction purpose (AASHTO classification).
Those involved in the materials testing side of the business should take a close look at the full list as there are also a number of updated standards relating to various asphalt and and aggregate tests, capping of concrete cyllinders and other related testing standards.
For my practice, perhaps the most significant standard that was updated was D 2488 – Standard Practice for Description and Identification of Soils (Visual-Manual Procedure) which we rely on for our field USCS classifications. I’ll be curious to see what those changes entail. Click through for the full list.
U.S. Army Corps of Engineers, New Orleans District to Implement Dataforensics PLog Enterprise for Geotechnical Data Management
Norcross, GA, July 6, 2009 – The U.S. Army Corps of Engineers, New Orleans District (USACE – NO) has issued a contract to Dataforensics, a leader in geotechnical data management software development and implementation, for its PLog Enterprise software. The contract not only includes deployment of the PLog Enterprise system but expanding its capabilities to work with Oracle databases and with ArcSDE technology.
