Aggregate resources, geology, and wells

Minnesota Geological Survey data:
shapefile:
 cwiwells - locations of wells in Renville County (point feature), 
            downloaded in 2002.  For more information about the County Well 
            Index, contact the Minnesota Geological Survey.
associated dbase table:
 cwistrat.dbf - geological descriptions used for this project.  Relate to the
            cwiwells shapefile using relateid.


Minnesota Department of Transportation data:
shapefile:
 asis0402 - Aggregate Source Information System data downloaded in April of 2002.


Division of Lands and Minerals, Mineral Potential Unit data:
shapefiles:
 renvagpln - aggregate potential, contacts between mapping units (line feature)
 renvagppy - aggregate potential, polygons (i.e., mapping units)
 renvfobs - field observations of various types made in the fall of 2002 and during 
            the spring of 2003 (point feature).
 renvgpits - locations of gravel pits, quarries, and sand pits mapped from a number 
            of sources (point feature).
 renvsgeoln - surficial geology, landform line symbols (those landforms that were
            too small to be mapped as polygons).
associated dbase tables, for use with gvl_pits shapefile:
 renvqual.dbf - quality data from MN/DOT pit sheets.  Relate on the sourcexx field 
            in renvqual.dbf and the asis_numbr field in renvgpits.

Documentation of these shapefiles can be found on this CD under the docs
subdirectory.
