Surface Cartography
Orbital scanners have been upgraded to resolve planetary surfaces for terrestrial planets, planetoids and moons. The scanners follow the Traveller5 cartography procedure, with the following departures.
- No trade codes. The full survey of the planet is consulted, not simply its trade classifications.
- Resources follow the resource rating. Resources are allocated according to the planet’s resource rating, and may occupy any hex, land or water, even one already bearing another feature.
- Life shades the land. Biomass readings colour the terrain, so that the scanners reveal where living matter takes hold of a world.
- Tidal locking is recognised only where the world is locked to a star. The twilight zone is drawn only where the survey data records one; a 3:2 resonance, for example, has none.
- Oceans of liquids other than water are coloured according to the liquid.
- Settlements are drawn from the census data, and on tidally locked worlds are placed along the twilight zones.
