tiler 0.2.0

CRAN release: 2018-06-09

  • All three gdal2tiles* scripts have been updated to accept a command line argument when called by R that provides a path for any temporary files, i.e., tmp.*.vrt files created by the gdal2tiles* scripts. These were previously accumulating in the system temp folder. The new temporary directory is a sub-directory inside tempdir(). Therefore, it is cleaned up when exiting R. Nevertheless, tile also force deletes this subdirectory immediately after its internal system call to one of the gdal2tiles* scripts returns, so the temporary sub-directory does not even exist for the full duration of the tile call.

  • Added arguments to tile. tile now generates previewer by default.
  • Added unit tests.
