A SpatialPolygonsDataFrame
containing 23 polygons whose union outline
boundaries of the state of Wyoming. Source shapefile was from the Census Bureau
in 2015; but, that shapefile has been taken down. A secondary source of the Wyoming
counties shapefile, with different attributes, is here:
https://www.arcgis.com/home/item.html?id=65b84d3d0c59441596c900d24196d4fd
Attributes of the polygons are:
STATEFP = State identifier (56 = Wyoming)
COUNTYFP = Unique identifier for county
NAME = Name of the county
The proj4string is "+init=epsg:26912} \code{+proj=utm} \code{+zone=12} \code{+datum=NAD83}
\code{+units=m} \code{+no_defs} \code{+ellps=GRS80} \code{+towgs84=0,0,0"
,
meaning among other things that the coordinates are projected zone 12 UTM's in meters.
