%description
Transform coordinates from a specified source to a specified target map
projection. This uses the 'PROJ' library directly, by wrapping the 'PROJ'
package which leverages 'libproj', otherwise the 'proj4' package. The
'reproj()' function is generic, methods may be added to remove the need
for an explicit source definition. If 'proj4' is in use 'reproj()' handles
the requirement for conversion of angular units where necessary. This is
for use primarily to transform generic data formats and direct leverage of
the underlying 'PROJ' library. (There are transformations that aren't
possible with 'PROJ' and that are provided by the 'GDAL' library, a
limitation which users of this package should be aware of.) The 'PROJ'
library is available at <https://proj.org/>.
