UI:Quadrant View

The Quadrant Display is equivalent to the 'galaxy map' in most 4X games. Let's take a closer look at what we can do here.

First, an overview:

Quadrant Display


System Information Display (SID)


To the left of the screen is the System Information Display. This is a dynamic display that only activates when you hover the mouse over an object such as a star.

Depending on what is displayed, there may be no information other than the system name and the sector information. The sector information color indicates who claims sovereignty over the system, which is not necessarily the same as owning the system. Green indicates that your Empire has a claim to this system, either with an outpost or a colony, and yellow indicates that the system is neutral or unowned.

Below that is any system edicts that are pending. Edicts are displayed in months elapsed/total months estimated. Note that this is just an estimate and it may fluctuate from turn to turn as the characters involved in the edict's stats and thoughts change.

Next comes the system planets. If the planet is unexplored but known, it will show up in a white color. Planets that you own or have an outpost on will show up in your empire color (light blue for the alpha). Planets that you own will also have additional information. This is:

  • the political rank of the planet
  • the ADM (Admin) of the planet available/total
  • total population/change from last month
  • current primary designation of the planet
  • current viceroy
  • any edicts that are in progress on the planet

The SID may be disabled by using hotkey 'I'.

Alert Bar


On the right side of the quadrant display is the Alert Bar. This will evolve as the game is more developed, but for now it will show alerts in 4 colors:

*green (informational, no action generally required)
*yellow (informational, but something fairly important)
*yellow-red (informational but very important, usually something that will become a major problem soon if ignored)
*red (critical item that is threatening a portion of your Empire; ignore at your peril!)

There are also 4 buttons that designate alert filters; you can select all, some, or none to display at any one time.

To go to an alert, you can left-click to enter the planet screen of the affected planet, or right-click to center the quadrant display on the affected system that contains the planet.

If there are no alerts, nothing will be shown.

Map Modes

There are several map modes in Imperia. The default map sub-mode is Mission Sub-mode.

  • Mission Submode('M' Hotkey) - shows dark green range circles showing which systems can launch missions and how far those missions can travel. Influenced by your empires warp technology level. Systems that fall outside this range of your eligible sector capital may not undertake a planet-level Edict - this will be shown in an alert message in place of the Edicts that are normally available for selection.
  • Migration/Colonization Submode('C' Hotkey)- shows larger dark green range circles from ANY inhabited system showing the range of potential migrating citizens. From the center of a system, a citizen can travel to any system in range of that circle. Therefore, systems that are overlapped with more circles show as a brighter green and are capable of being traveled to, and being the target of more migration.
  • Trade Submode('T' Hotkey) - Shows 3 circles: a small red circle around a system with a system-level trade hub, a medium-sized yellow circle around a system with a sector-level hub, and a large green circle around your empire trade hub. The circles are in size proportional to the size of the starbase that is present. If there is no circle around an inhabited system, no trade hub has been set up and no materials will move from that system to any hub except for your empire hub, at tremendous inefficiency.
  • No Submode('N' Hotkey) - Simply turns off all submodes.

In all modes, 'S' will toggle sector lines. Some map modes turn sector lines off by default; this hotkey will turn them back on.

Map Features


The Quadrant Display shows stars and connecting sector lines. Stars showing your empire's banner color are occupied by your empire. Stars in yellow are within your empire's astronomy capabilities, and thus have been surveyed, but are not actually owned. Stars in gray are not explored nor surveyed, and nothing is known about them beyond the star type.

Sectors are displayed with lines radiating from the system containing the sector capital. Sectors that systems are contained in are displayed below the star up to Zoom Level 4, and closer the star type is shown. Here, there are 2 sectors overlapping each other, Moscow and Rome.

Every star system in the quadrant is assigned to a sector whether or not it has been claimed. These sectors are considered to be held 'in trust' for the Empire as they are conquered/colonized/claimed. If at least one system is occupied in a new sector, a sector governor will be assigned by the system.

Systems that have Edicts in progress will have the designation (E:#) after the system name, where # is the number of edicts in progress at the system and planet level.

Map Controls

To pan the quadrant map, hold down the RMB and drag towards the location you wish to pan towards. To zoom in and out, use the mousewheel to zoom in and out. You are limited to zooming out to zoom Level .5 (quadrant view) and in to zoom Level 30. To select a system, left-click on it. This will take you directly to that system's System Display. To get back to the Quadrant Display from any part of the program, left-click on the ASTROGRAPHY mode button on the button bar at the bottom of your display.
