sim3181_readme.txt

These files constitute the digital database, in GIS format, for USGS 
SIM 3131, "Geologic map of the Suquamish 7.5' quadrangle and part of 
the Seattle North 7.5' x 15' quadrangle, Kitsap County, Washington" by 
Ralph A. Haugerud and Kathy Goetz Troost.

The database is presented in three formats:

1) Suquamish-gdb.zip: Contains Suquamish.gdb, an ESRI ArcGIS v. 9.3 
file geodatabase laid out in accordance with the NCGMP09 v1.1 database 
schema. A description of this schema is available at 
http://ngmdb.usgs.gov/Info/standards/NCGMP09/. FGDC-style metadata for 
each element of the geodatabase (table, feature dataset, feature 
class) are stored within the geodatabase. The zip file also includes 
report-level metadata, an ESRI .mxd file that describes a map image 
similar to that in Suquamish.pdf; a geodatabase that contains 
contours, roads, and PLSS lines used as the map base; and a RESOURCES 
folder that contains an ESRI .style file, related fonts, PDF-format 
files of report figures, and a PDF-format file of the report text. 
   Note that to obtain proper symbolization of some features using the 
included .mxd file it may be necessary to install the fonts in the 
resources folder. 

2) Suquamish-complete.zip: A complete, automatic translation of 
Suquamish.gdb into shapefiles, dbf files, and pipe-delimited text 
files for fields longer than 255 characters. Logfile.txt documents how 
fields were renamed to fit within the 10-character fieldname-length 
limitation of the shapefile format. Also contains report-level 
metadata and the RESOURCES folder described above. This complete 
version of the database contains all the content of the native 
geodatabase transcribed into well-documented, stable file formats. 
Unfortunately, in this form the information is not particularly easy 
to use.

3) Suquamish-simple.zip. Automatic translation of MOST of the contents 
of Suquamish.gdb into simple flat shapefiles. An easy to use, though 
incomplete, version of the database. The zip file also contains 
report-level metadata and the RESOURCES folder described above. 

These files, as well as a PDF file for a publication-quality image of 
the map sheet, are available at http://pubs.usgs.gov/SIM/3181/.

Note that digital, detailed lidar topography and composite bathymetry 
used as part of the base map are not contained in any of these files. 
Lidar topography is available from the Puget Sound Lidar Consortium, 
http://pugetsoundlidar.org 
(http://pugetsoundlidar.ess.washington.edu). Composite bathymetry is 
available (as of late 2010) at 
http://www.ocean.washington.edu/data/pugetsound/.
