\title{Tools, Shapefiles & Data to Work with an 'AlbersUSA' Composite Projection}
|
|
\description{
|
|
Creating a composite projection for states and counties of the United States
|
|
that includes scaled and shifted polygons for Alaska and Hawaii is time consuming
|
|
and potentially error-prone. Functions and data sets are provided to make it easier to
|
|
produce maps with a composite projection. Furthermore, named projections for common
|
|
transormations are provided to further increase mapping productivity.
