SectorMaker is a game aid for Far Future Enterprises’ Traveller5™ role-playing game that facilitates the creation of sector star charts with subsector names, world details, political allegiances, labels, regions, borders, and trade and communication routes. Sector, subsector, and world maps are made possible by the use of Joshua Bell’s POSTER API at the Traveller Map website. Note that an internet connection is required for mapping functionality. A big thank you to Joshua for providing this great resource for Traveller fans. Data for a specific sector and era may be imported from Traveller Map for reference or editing. Data export lets you print maps using Traveller Map's Poster Maker. SectorMaker star generation and world creation features follow the rules in the Charting the Stars chapter of the Traveller5 version 5.10 Core Rules, copyright 2019 Far Future Enterprises.
