addresses of U.S. Representatives for Oklahoma.
Abstract:
This data set contains the U.S. 104th Congressional district
boundaries and names and addresses of U.S. Representatives for
Oklahoma. This data set was developed from the U.S. Bureau of
Census TIGER Extract thinned boundary files by the U.S. Geological
Survey.
Entity_and_Attribute_Overview:
Each polygon has six attributes. The first attribute, ST, is the
state FIPS code. The FIPS code for Oklahoma is 40. The second
attribute, CD, contains a code (1 to 6) indicating the
U.S. congressional district. The third attribute, REP, contains the
name of the U.S. Representative for Oklahoma. The fourth attribute,
PARTY, contains an R indicating the political party of the
Representative is Republican. All of the 104th U.S. Congressmen for
Oklahoma belong to the Republican political party. The fifth
attribute, ADDRESS, contains the street address of the
U.S. Representative. The sixth attribute, CITY_ZIP, contains the
city and zipcode of the U.S. Representative.
In the DLG version of this data set the attributes are stored in
the associated file USCONGR.DBF. This file is in a dBASE format and
can be appended to the polygon attributes using software compatible
with the dBASE format. The item USCONGR_ is stored in the first
major code (MAJOR1) and the item USCONGR_ID is stored in the first
minor code (MINOR1). Either item may be used as the link item when
joining USCONGR.DBF with the polygon attributes.

point attributes and X and Y coordinates are stored in USGSSIT.DBF.
Entity_and_Attribute_Overview:
The point attribute table contains 20 attributes for each record.
AGENCY contains the agency code (all records are USGS for
U.S. Geological Survey). SITE contains the station identification
number. DLAT and DLONG contain the latitude and longitude in
decimal degrees. ELEVM and ELEVFT contain the elevation in meters
and feet above the NGVD29. STATE contains the state postal
abbreviation (table 3) where the station is located. STATYPE
contains a station type code (table 4.) STANAME contains the
station name. GMTOFFSET contains the hour offset, from Greenwich
Mean Time of the recorded time at the station. STDTIME contains a
"Y" if the station time switches to daylight savings time. BEGYEAR
and ENDYEAR contain the first and last years of station record.
Stations with ENDYEAR 1996 are considered operating. HUC contains
the eight-digit Hydrologic Unit Code. DAREAKM and DAREASQM contain
the total upstream drainage area, in square kilometers and square
miles. CDAREAKM and CDAREASQM contain the contributing upstream
drainage area, in square kilometers and square miles. REMARKS
contains remarks about the station. X-COORD and Y-COORD contain
the X and Y coordinates of the station in the map projection
coordinate system. The attribute code, -999, indicates data are
missing or unknown.

WATRSHD
Description:
Watershed boundaries for Oklahoma.
Abstract:
This data set contains watershed boundaries for Oklahoma and
cataloging-unit boundaries for the remaining Arkansas, Red, and
White River basins. This data set was originally published by the
U.S. Geological Survey in the 1994 report titled,"Watershed
boundaries and digital elevation model of Oklahoma", by Cederstrand
and Rea. The watershed boundaries were delineated from a
hydrologically-conditioned digital elevation model covering
Oklahoma, followed by interactive editing to revise the boundaries
where they were not consistent with hypsography and hydrography
from 1:100,000-scale U.S. Geological Survey topographic quadrangle
maps.
Entity_and_Attribute_Overview:
The arc attribute SOURCE has six special codes to describe the
source of the linework. The first four codes were adopted from a
data set of hydrologic units for the conterminous United
States. Code 1 indicates arcs that were from 1:100,000-scale GIRAS
files and were internal to the quadrangle (no map neatlines). Code
2 indicates arcs from the 1:250,000-scale GIRAS files that were
internal to the quadrangle. Code 3 indicates lines from either the
1:100,000-scale or 1:250,000-scale GIRAS source but were part of
the neatline that may be used to connect arcs that do not join
cleanly between quadrangles. Code 4 indicates the arcs within the
Oklahoma state boundary that were derived from the DEM. Code 5
indicates the Oklahoma state boundary. Code 6 indicates
watershed boundaries that were interactively revised based on
1:100,000-scale hypsography data from U.S. Geological Survey DLG
file and U.S. Environmental Protection Agency Reach File, version
3.0 alpha, hydrography data.
The DLG version includes one major and one minor line
attribute. The line attribute MAJOR1 contains the SOURCE codes
discussed above and the MINOR1 attribute is always zero.
Several special polygon attributes are used to show the hierarchy
of hydrologic units. HUC11 contains the full 11-digit code for a
watershed. This attribute ends with three blanks if the hydrologic
unit is outside Oklahoma. HUC4 contains the four-digit subregion
code and is the first four digits of HUC11. HUC6 contains the
six-digit accounting-unit code and is the first six digits of
HUC11. HUC8 contains the eight-digit cataloging-unit code and is
the first eight digits of HUC11. WSCODE contains the three-digit
watershed code and is the last three digits of HUC11. WSCODE is
always blank outside of Oklahoma.
The DLG version includes two major and minor pairs of polygon
attributes. MAJOR1 contains the first four digits of HUC11, MINOR1
contains the next four digits of HUC11, MAJOR2 contains the last
three digits of HUC11, and MINOR2 contains the area in square
miles. The arc attribute MAJOR1 contains the SOURCE codes discussed
above and the MINOR1 attribute is always zero.

Abstract:
This data set consists of meteorological station records from
several different sources, including the Oklahoma Mesonet, the U.S.
Department of Agriculture, Agricultural Research Service, and the
National Climatic Data Center of the National Oceanographic and
Atmospheric Administration. The records contain location, type, and
period of record for stations, but do not contain actual
measurement values such as temperature, precipitation, or other
meteorological parameters. Both operating and discontinued stations
are included in this data set.
The transfer file format for WEATHER is a dBASE format file. The
point attributes and X and Y coordinates are stored in WEATHER.DBF.
Entity_and_Attribute_Overview:
The point attribute table contains 16 attributes for each
record. AGENCY contains the agency code (table 3.) SITE contains
the station identification number. DLAT and DLONG contain the
latitude and longitude in decimal degrees. ELEVM and ELEVFT contain
the elevation in meters and feet above the NGVD29. STATE contains
the state postal abbreviations (table 4) for the state where the
station is located. DATSOURCE contains codes identifying the
source of the data (table 5). STANAME contains the station
name. GMTOFFSET contains the hour offset, from Greenwich Mean Time
of the recorded time at the station. STDTIME contains a Y if the
station time switches to daylight savings time. BEGYEAR and ENDYEAR
contain the first and last years of station record. Stations with
ENDYEAR of 1993 or -999 were considered operating when these data
were originally published. REMARKS contains remarks about the
station. X-COORD and Y-COORD contain the X and Y coordinates of the
station in the map projection coordinate system. The attribute code
-999 indicates data are missing or unknown.
