First official public screenshot of HoI4's map & interface, from the 7th February 'Our Vision' dev diary

The map is where most tactical and strategic decisions happen. It also provides information related to these purposes, such as, weather, air combat, land combat, naval combat, and buildings.

Map divisions

The Map can be divided into four subdivisions:

• Provinces are the smallest subunit of the map, it is here that terrain, weather, capitals, land combat and victory points are handled.

• States are the next smallest subunit of the map, where construction, manpower, population, and country borders are decided.

• Supply areas are the next largest subunit of the map, here logistics and supply are handled.

• Strategic Regions are the largest of the subdivisions, and are where naval combat and air combat occur.

Map modes

The map mode icons.

Using different map modes, you can alter the information presented on the map. These map modes can be activated by either clicking on the appropriate button (icon) located in the lower right corner of the main screen or by pressing the associated hotkey.

默认地图模式

The Default map mode without the day/night loop.

Shows sovereign nations and armies.

The default map mode is a combination of the political map mode and terrain map mode from previous games. It shows the name of all the nations, with their political color. Zoomed out, mainly the nation's color is seen, however, when zooming in, the terrain becomes more and more visible, integrating both map modes into one. Air fields, naval bases, capitals, and almost any other object on the map can be seen in this mode, represented by different symbols:

• Naval bases are anchors.
• Airfields are a top down picture of an airplane.
• Capitals are a star, which can be green if it is the nation's capital, gray if they are any other nation's capital, or red if they are the capital of any of the nation's enemies.
• Victory points are denoted by a small dot, which have a name when zoomed in, and particularly high value victory points are denoted by a slightly larger dot. They follow the color scheme of capitals.
• Units can be seen as counters or sprites on the map.
• Battles can be seen as pointers that are green if the nation is winning the battle, yellow if the battle is favoring neither side, or red if the nation is losing the battle, and it shows a number that summarizes how much the battle favors one side or the other.
• Naval combat can be seen along with navies and their missions.
• Aircraft can be seen flying where aircraft are in operation.
• Forts and any other state- or province-wide constructions are also visible.
• Demilitarized zones will be a red outline around any demilitarized area, such as the Rhineland.

Strategic navy map mode

The Strategic Navy map mode.

Shows strategic regions relevant to naval activity, with information on naval supremacy and naval tasks.

The naval map mode consists of the world's strategic regions, with a color scheme similar to the diplomacy for states on land under it. Convoy routes are also shown here with the following color scheme:

• Blue trade routes are resource transfers. These are imports, exports or resource transfers from owned oversea resources.
• White trade routes are supply transfers to oversea units.
• Green trade routes are lend lease routes.

Trade routes require convoys to operate.

Strategic regions that have sea provinces will be highlighted with green if they are under allied naval superiority. Provinces that are striped red are out of the fleets' operational range.

Straits

Canals or any type of controlled strait are shown on this map mode, and by hovering over them it is possible to see the access permissions your country has as well as the land provinces controlling the strait (blue outline). Straits are also shown on the Supply Map Mode and the Resource Map mode.

The following, are the names and province control points of the straits/canals on map and their respective permissions granted to nations (depending on the relations with the strait controllers).

Name	Province Control	Unit Permissions	Contested?	Enemy	Friend	Neutral
Suez Canal	Cairo, Sinai	Armies	No	No	Yes	Yes
		Navies

		Trade				Yes
The Panama Canal	Panama Canal (US occupied), Panama	Armies	No	No	Yes	No
		Navies				No
		Submarines				No
		Trade				Yes

Strategic air map mode

The Strategic Air map mode.

Shows strategic regions with information on aerial supremacy. It is automatically activated when an air base is selected.

The air map mode is, at first glance, merely a map of the strategic regions of the map. However, when at war, the regions can be highlighted with three colors:

• Red, which means the enemy has air superiority.
• Green, which means the nation or its allies has air superiority.
• Yellow, which means the air superiority is contested.

This map mode also shows all of the air missions currently set with the total number of planes assigned.
In the strategic air map mode more ground crews can be assigned, by clicking the icon in the desired strategic region. This gives a +10% bonus to mission efficiency in the strategic region.

Supply areas map mode

补给区域地图模式

在补给区域地图上，展示了世界上的各个补给区域。就面积来说，一般补给区域比战区小，比单个省大。补给区往往由多个省组成。由国家及其盟友控制的补给区域中，驻扎了军队且没有超过可供应补给上限的会显示为Template:绿色。补给区颜色为red表示不能为该区域内所有军队提供补给。没有军队，也即不需要补给的地区没有颜色。此外，海岸与邻国的补给区显示为Template:蓝色。该模式下显示海洋贸易路线，同海军战略地图一样。

Each supply area has a symbol that has a barrel and crates , next to a railway track , and finally there may be an anchor if the supply area is coastal and has one or more naval bases. Each icon provides associated numerical information:

• The barrel and crates has a number on the icon, for example, 0/114. The first number is how much total supply is being used by friendly and allied forces, rounded to the nearest integer. The total supply includes army, navy, and air forces. The second number is the supported supply limit.
• The has a number below it which is the total infrastructure across all states the supply area encompasses.
  • Clicking on the will queue one infrastructure for each state in the supply area for each click, as long as it does not exceed a total infrastructure of 10 in a state. If infrastructure construction is queued anywhere within the supply area, this number will appear in yellow and be expressed in an "x/y" format where "x" is the final total infrastructure, and "y" is the current infrastructure.
  • When hovering the cursor over a supply area, the will also have a number above it, appearing in either white or red. This number appears to reflect the total supply throughput, measured as 2.5 times the square of the average infrastructure level in the supply area, rounded down (this is equivalent to the sum of the calculations performed to determine overland incoming supply if the same supply area in question was considered both the receiving and sending area). If this number is red, it means the supply area is bottlenecked, i.e., the supply area could potentially receive more incoming supply, and pass along more supply, if the infrastructure in the supply area is upgraded.
  • Note that in the case where a supply area is coastal and its incoming supply arrives from overseas, the infrastructure's top number will instead be only 2 times the square of the average infrastructure level (i.e., there is no overland "sending" area).
• The , if it is applicable to the supply area, has a number below it which, unlike the infrastructure, is the highest naval base level in the supply area.
  • Clicking on the will queue a single upgrade of the highest-level naval base in the supply area. If upgrades to the highest-level naval based are queued, this number will appear in yellow and be expressed in an "x/y" format where "x" is the final total level of that naval base, and "y" is the current level.
  • When hovering the cursor over a supply area, the will also have a number above it, appearing in either white or red. This number appears to reflect the amount of supply that can be received from or passed forward overseas through naval bases in the supply area, measured as three times the sum total level of all naval bases in the supply area (this is equivalent to performing the overseas incoming supply calculation, while ignoring whether the originating naval base might be of a lower level). Similar to the infrastructure's top number, if this number is red it means it is bottlenecked, i.e., the supply area could potentially receive more incoming supply if the naval base or bases in the supply area are upgraded.
• Note that hovering the cursor over a supply area will reveal an arrow showing the supply chain's path from the national capital to the area in question, and will reveal the infrastructure and naval base top numbers over each supply area in the chain. A red number indicates only the current bottleneck in the entire chain. Therefore, only one of the incoming supply paths in the area over which the cursor is hovering, either the infrastructure or naval base(s), can be currently bottlenecked. Accordingly, only one of these two numbers may appear red at any given time. If both numbers are white, there is no bottleneck in that supply area, but there may be a bottleneck elsewhere in the supply chain.
  • A bottleneck in the capital supply area's infrastructure simply indicates that not all states in that area have infrastructure fully upgraded to level 10.

The calculations and consequences of these numbers are further detailed on the Logistics page.

Terrain map mode

Land terrain in terrain mapmode.

Naval terrain in terrain mapmode.

The terrain map mode shows the terrain of each region on the map using simplified colors. Land terrain has high adjusters for attack, defense and movement of land units. The terrain map mode can be useful to plan your offense or defense in for you favorable terrain.

Colors of the terrains:

• Plains: Brown
• Forest: Green
• Jungle: Green
• Marsh: Green/blue
• Hills: Light grayish with a bit yellow or green
• Mountain: Gray
• Urban: Dark Gray with road patterns
• Desert: Yellow
• Ocean: Blue
• Deep ocean: Dark blue
• Shallow sea: Light blue
• Fjords and archipelagos: Cyan

Resistance map mode

Resistance map mode.

The resistance map mode shows resistance per state. Yellow indicates low, orange higher and red high resistance.
The percentage of resistance (0%-100%) is shown for each state. A green arrow downwards shows decreasing resistance, a red arrow upwards increasing resistance.
Also 3 resistance tiers are shown:

• Organized Resistance if the resistance is >25%
• Emboldened Resistance if the resistance is >50%
• Uprising if the resistance is >75%

Compliance map mode

Compliance map mode.

Shows compliance per state. Lighter blue means more compliance.
The percentage of compliance (0%-100%) is shown for each state.
Also 5 compliance tiers are shown:

• Informants if the compliance is >15%
• Local Police Force if the compliance is >25%
• Reorganized Workforce if the compliance is >40%
• Volunteer Program if the compliance is >60%
• A New Regime if the compliance is >80%

Resource map mode

The Resource map mode.

Shows resource locations and trade routes.

The resources map mode shows any convoy/ trade routes that are connected to the nation and canals/ straits across the world, similar to the naval map mode. However, this map mode looks like the default map mode when zoomed out, but when zoomed in, it shows a resource icon above any state that has a resource, along with the number of that resource produced in that province.

Diplomacy map mode

The Diplomacy map mode.

Shows diplomatic relations.

The diplomacy map mode shows its information through a multitude of colors.

• Green is the color that any land owned and controlled by the nation
• Light green is the color that any land occupied by the nation will be colored.
• Dark green is the color of any nation that has very good relations with the nation.
• Red is the color of any nations that the nation is currently at war with.
• Light red is the color of friendly territory that is occupied by enemies.
• Neon orange is the color of countries that the nation has wargoals against.
• Light orange is the color of any country the nation has very bad relations with.
• Blue is the color of any allied nations.

Factions map mode

The Factions map mode.

The factions map mode shows the factions that exist around the world. The faction is colored the color of the leader nation, i.e. the Axis is grey due to the color of Germany, and it stretches across all nations in that faction.

States map mode

The States map mode.

Shows states and population/ state category.

The states map mode shows an outline of every state in the world. These outlines are different colors based on the population of the state/ state category. This directly controls how many factories are allowed to be built in a state. The type of state can be found by simply hovering over it.
