Topology

Related class: Topology of New Eden (planned)

At first glance, New Eden is a complex mess of points. In addition to that, jump gates often don't connect to the closest systems. There are many arms and dead ends, and a number of highways - routes that are particularly short for the distance they cover. There are also high sec chokepoints: Systems that you need to pass through in order to travel between two given high sec systems without leaving high sec. Since the ingame map arranges systems by their coordinates, some of these relations can be hard to see, but they are useful to know for pilots in the high-sec trading or hauling businesses.

The Ring Topology of High Sec Empire Space

Topologically, high sec is a ring that consists of the systems that are claimed by the four major factions (with the exception of the Jovian Empire). Among the minor factions, the Ammatar Mandate is special in that it is also located on the ring. A small part of the Amarr Empire is separated from the Empire's main high sec space, and only reachable through CONCORD/Gallente space. The basic layout of high sec can thus be visualized as follows:

The main idea you should take away from this picture is that in order to travel from e.g. Aldrat (in Minmatar space) to Jita (in Caldari space) without leaving high sec, you need to travel through either Gallente space, or through Amarr/Ammatar space. There are shorter routes, but they all involve at least one low sec system.

Highways and Chokepoints

In addition to resembling a ring, high sec jump routes are also structured so that systems exist that are located directly on the ring as well. This means that in any route between faction spaces that is sufficiently long, there are also individual systems you must pass through if you want to stay in high sec. In the above example (Aldrat-Jita), you need to pass through the Colelie system in order to reach Gallente Federation space, and in order to get from Gallente space to the main Caldari region, you need to pass through the Sivala system between the Caldari Border Zone and the Caldari State region. Likewise, every other high sec trade route between a Minmatar system and a Caldari system also passes through Colelie. Because high sec resembles a ring, there is one alternative path around the other side of that ring (in this case: through Ammatar and Amarr space). This alternative path has similar systems on it, though. Systems like Colelie and Sivala are, therefore, high sec chokepoints. To put it plainly, they are the kind of system where you would hang out if you were in the business of liberating innocent trade goods from their trader oppressors.

Another aspect of the layout of High Sec space is that some routes are much shorter than others. Using the same example as above, the shortest path between Aldrat and Jita passes through the two systems Aufay and Balle. While it isn't necessary to travel through these two systems, by default, the autopilot will choose a path through them for you if you only tell it to avoid low sec. Since people in general are lazy and will either prefer the shortest path or just trust their autopilots blindly, these systems form highways: Routes that see a lot of pass-through traffic even though they are not strictly required to pass through. This makes them almost as good as chokepoints if you are in the liberation business.

Highways and chokepoints also exist outside of the ring. Again using the same example, in order to reach the remainder of Minmatar space from Aldrat (or in order to return to Aldrat), you must pass through the Eygfe system. On the other end of the example route, the systems Urlen and Perimeter are on a popular shortest path between most of Caldari space and Jita. In particular, the Jita gate in Perimeter and the Perimeter gate in Jita are popular destinations for smartbombing battleships as well as for scouts who would like to scan your cargo.

Low Sec Shortcuts

Since traveling along the ring can involve a large number of jumps through high sec, there are numerous routes through low sec that are considerably shorter. Systems on common shortest paths between empire factions form highways in the same way as they do in high sec. These systems also serve as popular entrances to low sec for pilots who wish to travel there. The notorious pirate strongholds Amamake and Rancer are two such systems.

High Sec Topology with Chokepoints

The following map attempts to visualize the entire ring of high sec empire space, including all chokepoints on the ring. Seven chokepoint systems between Lashesi and Esescama that are directly connected to each other have been omitted. Highway systems that are not chokepoints have been included based on their notoriety, and popular destinations and hubs likewise.

Notes:

• Everything that is drawn directly on the ring is part of the ring and can't be avoided in any way other than traveling around the ring in the other direction, or by traveling through low sec.
• In particular, this makes individual systems directly located on the ring chokepoints.
• Everything that is drawn outside of the ring is connected to the ring as indicated.
• Systems outside the ring are on common shortest routes, i.e. they form highways. To distinguish between highways and chokepoints, highways that are not chokepoints are shown using dashed lines. In particular, the Eygfe system is a chokepoint on the route to Aldrat, and while the route thas passes through Aufay and Balle is only a highway, the Aufay and Balle systems are chokepoints on that highway.
• Routes to any low sec systems are shown as red lines. There is no distinction between low sec chokepoints and highways because there are no real chokepoints as soon as you are prepared to leave high sec.

High Sec Enclaves

There are high sec systems that have no high sec connection to the main empire region. Several systems in the Molden Heath, Solitude or Aridia regions are examples of this. While these play no large role in the grand scheme of things of high sec life, you should be aware that they exist. It is entirely possible that a courier contract with innocent-looking high sec source and destination systems requires travel through lowsec or nullsec.

Low Sec Topology

Hopefully forthcoming: Important places and routes in low sec.

Null Sec Topology

Hopefully forthcoming for completeness' sake...
