(1) vector spatial data layers in ArcView shape file format for surficial geologic units and contacts, cross-section line locations, water bodies and data points for stratigraphic test holes, outcrops, ISGS field notes, water wells, and engineering borings;
(2) JPEG browse images of the final published map;
(3) metadata in FGDC compliant format for all spatial layers and
The vector data include name for geologic unit, map symbol, and a line-type indicator.
Vector data are in the geographic coordinate system, decimal degrees, NAD83.
For a detailed list of the files included in the data product, see the Supplemental_Information section.
The data were published in 2001 on an ISGS Illinois Geologic Quadrangle entitled Surficial Geology Map, Elburn Quadrangle, Kane County, Illinois by David Grimley. The data in this compilation do not include all the information on the published map. Refer to the published map for a complete explanation of the Quaternary geology of the Elburn quadrangle.
The nominal scale is 1:24,000.
