USAboundaries 0.3.0
Moved most data to USAboundariesData. This improves loading time and
permits more frequent updates to the user-facing package.
Added state plane projections table and functions (@jfbratt). Now users can
get an appropriate projection for a state.
Converted all boundary objects to sf objects.
Updated all contemporary census boundaries from the 2014 to the 2016
versions.
Added zipcode tabulation area centroids.
Added historical city populations compiled by Erik Steiner at
CESTA/Stanford University.
USAboundaries 0.2.0
Added contemporary boundaries for states, counties, and
congressional districts.
Import many fewer packages. The us_boundaries()
function no longer has an option to return a fortified data frame. It is
assumed that users will convert the
SpatialPolygonsDataFrame objects to whatever format they
need.
High resolution data is now available in the USAboundariesData
package.
USAboundaries 0.1.1
Fix to README.md as requested by CRAN.
