Lead-rich sediments, Coeur d'Alene River valley, Idaho; Area, volume, tonnage, and lead content: Geologic and wetland unit data

This metadata file (cdafldpl.met) describes three shape files.
Shape file cdasurf4_utm.shp, with its associated .shx and .dbf files,
contains polygons and attributes for a map of geologic and wetland
units and systems, which represent sedimentary depositional
environments of the Coeur d'Alene (CdA) River valley. This map extends
beyond the lateral and longitudinal boundaries of the area studied
for this report.
Shape file fldpln2.shp was derived from shape file cdasurf4.shp by
trimming it to the study area for this report, which includes the
CdA River channel and floodplain, from the confluence of its North
and South forks, to the base of its delta, in CdA Lake.
Shape file fpaream2.shp was derived from fldpln2.shp by merging its
1544 polygons into one polygon, representing the 85 square-kilometer
area studied for this report.
