This is an R script for converting vector, points lines and polygons digitised from old Greek military HATT projection map sheets to the Greek national grid (the latter being better described via EPSG etc.). Ideally this would all have been done for the PROJ4 library, but ran out of time. There is an example script in the examples folder, for polygon and point datasets respectively.
Many thanks to Leonidas Liakos for providing the mapsheet coefficients and Denitsa Nenova for further help.
