Cartographic Overlay
Signal Summary
The galaxy is not a uniform disc. It has a dense central bulge, broad spiral-arm structures, sparse gaps between arms, and named regions that explorers use as a shared language.
Cartographic regions help convert raw coordinates into a story: where the commander is, what kind of density to expect, and what route constraints may appear next.

Key Concepts
Core - Dense central region with short average jump distances and many route alternatives.
Arms - Long stellar lanes where density stays high enough for conventional travel.
Gaps - Lower-density space between arms where jump range and fuel planning matter more.
Rifts - Named sparse regions that often become exploration milestones.
Field Notes
Exploration routes often feel easy along arms and suddenly fragile when crossing between them.
Named regions are useful UX labels for galaxy-map tiles, route summaries, and historical travel logs.
The same physical region may matter differently to explorers, traders, and lore hunters.
Reference
| Signal | Value | Use |
|---|---|---|
| Dense route zone | Core | Many systems within short jump range. |
| Long-range crossing | Arm gap | Fewer stars; route plotting can fail with low jump range. |
| Navigation label | Region name | Human context layered over raw coordinate data. |
