Map creation:

Vector/raster maps can be easily draw with xfig, a freeware drawing program for X-Windows environment. Xfig allows saving the maps in image formats or Postscript. Luckily it can handle BIG raster maps. You can define the paper size and the current version offers a "scale window" to tell you the line lengths in ground coordinates (e.g. line length in meters) while drawing. This is very helpful for creating the coordinate system map borders and for measurement.
