layerName

encoding string (.e.g. 'latin1') passed to rgdal::readOGR()

encoding

Raw shapefiles are read in using the <code>rgdal::readOGR()</code> function from the rgdal package.
Spatial data are reprojected onto a standard projection with a CRS class of
<code>"+proj=longlat +ellps=GRS80 +datum=NAD83 +no_defs"</code> before being returned.
If shapefiles have no projection information they are assumed to 'geographic' coordinates and will be assigned
<code>"+proj=longlat +ellps=GRS80 +datum=NAD83 +no_defs"</code> before being returned.

internal

A suite of conversion scripts to create internally standardized
spatial polygons data frames. Utility scripts use these data sets to return
values such as country, state, timezone, watershed, etc. associated with a
set of longitude/latitude pairs. (They also make cool maps.)
