Package {jpmapdata}


Title: Boundary Data for Japan Maps
Version: 0.1.0
URL: https://github.com/yhoriuchi/jpmapdata
BugReports: https://github.com/yhoriuchi/jpmapdata/issues
Description: Provides boundary 'GeoPackage' files used by the 'jpmap' package, including Japan prefecture example boundaries and official MLIT N03 administrative area data converted for 'jpmap'. Keeping these data in a separate package lets 'jpmap' update its functionality without repeatedly redistributing large boundary files on CRAN mirrors.
