sa99_d00: The boundary dataset for the 20 U.S. Seer Registries.

In SeerMapper: A Quick Way to Map U.S. Rates and Data of U.S. States, Counties, Census Tracts, or Seer Registries using 2000 and 2010 U.S. Census Boundaries

Description

This dataset contains a Spatial Polygons data frame for the 20 U. S. Seer registry areas boundaries as of the U. S. 2000 or 2010 Census years. Since the Seer Registries boundaries are the same for the 2000 and 2010 census, a single sa99_d00 dataset is used by the SeerMapper mapping packages for the NCI Seer Registry boundary data and information. The boundaries are used to map data by U. S. Seer registry area, to provide an overlay to state, county and census tract maps with the Seer registry areas boundaries, and provide a intermediate boundary for drawing census tract or county boundaries. When doing counties or census tracts level mapping, the SeerMapper package can be used to map the sub-areas within a registry that only have data or can expand the hsa, county or census tract boundary's drawn to include all sub-areas up to a Seer Registry or State boundary. This feature is controled by the hsaB, countyB and tractB call parameters. For more details see below. The Seer registry area boundaries mapping is controlled by the seerB call parameter. When set to "NONE", no Seer registry area boundaries are drawn on county or census tract maps. If set to "DATA", the Seer registry boundaries will be drawn for any Seer registry area containing sub-areas with data. If set to "STATE", all Seer registry boundaries will be drawn in a state that contains a sub-area with data. If set to "ALL", all Seer registry boundaries will be drawn.

Usage

data(sa99_d00)

Format

The dataset contains a SpatialPolygon data.frame of the 20 U. S. Seer registry areas based on the 2000 and 2010 U. S. Census county boundary data and index information for use by SeerMapper. The Seer Registry boundary and information are the same for both census years.

An registry area may contain multiple polygons. For more details, refer to the SpatialPolygon structure descripted in the "sp" package documentation. The SpatialPolygons is constructed to have all of the polygons for a single registry contained under a single SpatialPolygon instead of several. The 20 U. S. Seer registry areas are identify by character abbreviations:

saID	stID	Name
AK-NAT	02	Alaska Natives
AZ-NAT	04	Arizona Indians
CA-OTH	06	California Other (not SF-Oakland, SJ-Monterey, LA areas)
CA-SF	06	California San Fran/Oakland
CA-SJ	06	California San Jose/Monterey
CA-LA	06	California Los Angeles
CT	09	Connecticut
GA-OTH	13	Georgia Other (not Atlanta or Rural areas)
GA-ATL	13	Georgia Atlanta
GA-RUR	13	Georgia Rural
HI	15	Hawaii
IA	19	Iowa
KY	21	Kentucky
LA	22	Louisiana
MI-DET	26	Michigan Detroit
NJ	34	New Jersery
NM	35	New Mexico
OK-CHE	40	Oklahoma Cherokee Nation
UT	49	Utah
WA-SEA	53	Washington Seattle-Puget Sound

When mapping Seer registry area level data, the Seer registry area abbreviated name must be used.

The data slot of the SpatialPolygonsDataFrame (sa99_d00) contains information on the associated state, region identifiers, the centroid of the registry, and the number of counties and tracts in the registry.

The data slot can be used to identify the states associated with the active Seer registry areas.

Details

When Seer Registry boundary be used to draw all of the county and tract boundaries up to the registry boundary to be able to provide a complete county or tract mapping within the registry. This is cone by setting either the countyB or tractB call parameter to "SEER". This feature works the same as setting these call parameters to "STATE", but the boundary is the Registry boundaries.

The PROJ.4 projection used for these boundaries is:

"+proj=aea +lat_1=33 +lat_2=49 +lat_0=39 +lon_0=96W +ellps=WGS84"

The sa99_d00 dataset is a SpatialPolygonsDataFrame (SPDF). The spatial polygons represent the Seer Registry boundary data. The data slot of the SPDF contains the following information about Seer Registries:

row.names

The row.names attribute of the SPDF are character vectors and are set to the Seer Registry abbreviations as listed above.

ID

- character string representing the Seer Registry ID, the Seer Registry area abbreviation. saID and ID values provides the linkage between Seer registry area level data provided by the user and the Seer registry area boundary data. These abbreviations must be used. This field is the same as the row.names of the SPDF.

saID

- same as ID. The Seer Registry Identifier.

stID

- the state ID containing the Seer Registry. The stID is the 2 digit fips code for the state containing the Seer registry area. One state may be a Seer registry area or contain multiple Seer registry areas. But no Seer registry area spans multiple states.

stName

- character vector of the state name containing the Seer Registry.

rgID

- the U. S. census region ID containing the Seer Registry.

c_X

- a numeric value of the centroid's X coordinates.

c_Y

- a numeric value of the centroid's Y coordinates.

county00

- a numeric value of the number of tracts in the Seer Registry in the 2000 census.

county10

- a numeric value of the number of counties in the Seer Registry in the 2010 census.

tracts00

- a numeric value of the number of counties in the Seer Registry in the 2000 census.

tracts10

- a numeric value of the number of tracts in the Seer Registry in the 2010 census.
