The Virginia Department of Transportation (VDOT) Geologic Sections dataset consists of site-specific, large-scale geologic cross-sections (composite sheets). These sections were acquired from VDOT in order to save them from disposal. There are 5,500 geological profiles created for highway construction projects containing extensive core, auger and split-spoon logs at scales of 1:50 and 1:100 providing a unique record of subsurface geological and geotechnical data along roadways throughout Virginia. The thousands of feet of vertical subsurface data represents millions of dollars of investment in data acquisition by VDOT. The sections are useful as indicators of subsurface geology in large parts of Virginia. ...

Technology doesn’t stand still and neither does the vegetation mapping program. With 9X9 film and film cameras becoming increasingly rare, the 2010 systemic aerial photo effort will use a digital mapping camera to collect 8”/pixel imagery above Lock & Dam (L&D) 13 and 16”/pixel imagery below L&D 13 and along the Illinois River floodplain. There are two main reasons for this distinction; 1) the floodplain above L&D 13 is narrower and contains a greater amount and diversity of aquatic vegetation, and 2) below L&D 13, the Upper Mississippi River is largely channelized, with less aquatic vegetation, and wider, leveed floodplains dominated by agricultural use. This holds true for much of the Illinois River as well...

In the late 1880's and early 1900's the Mississippi River Commission (MRC) conducted an extensive high-resolution survey of the Mississippi River from Cairo, Illinois to Minneapolis, Minnesota. These data were published as a series of 89 survey maps and index. Other data on the maps that were not automated include; elevation contours, water depth soundings, proposed water control structures (e.g., wing dams), levees, benchmarks, railroads, and city streets. However, this information is available since these maps were scanned, georeferenced, and mosaicked by pool and are served on the Center’s web site. In addition to the mosaics, in the 1990's, the Upper Midwest Environmental Sciences Center (UMESC) in conjunction...

The Critical Minerals project in Maine produced a database of published and unpublished sources of information that describe important undiscovered potential mineral resources in the state. Information on focus areas for exploration is also included. Materials provided upon request.
