Abstract: Coverage of USGS DLG hydrography features

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Process description:
The polygon and line DLG coverages of hydrography features for 
each 1:24,000 dlg coverage for the state of Florida were converted to 
ARC/INFO coverages then mapjoined, cleaned, and built into individual
coverages.  The coverages were projected to Albers Equal Area projection
using A/I 7.0.3 for the DEC/Alpha.  The coverages were inserted tile by 
tile into the water_quad library.
