The following files are in gif format. They can be downloaded for use in a paint program, to easily customize worlds, sectors, and subsectors for your Traveller campaign. The hexgrid.gif is exactly what it sounds like: a sheet of graph paper with hexes rather than squares. The second file, worldmap.gif is a geodesic map for detailing an individual planet. It is based on "IS Form 21" from MegaTraveller World Builder's Handbook. The last file is a subsector map grid or "TAS Form 6" from Traveller, Book 3, Worlds and Adventures. Each form will fit on an 8.5" by 11" sheet of paper when printed.
