This is overview of 2D map features, as they appear in briefing and in-game 2D map as well as a part of the result of TOPOGRAPHY cheat output.

It is possible to have 3 types of graphical representation for roads in Arma:

• field track - as in original OFP, width as Roadway LOD
• road - black outline, pale yellow fill, width as Roadway LOD
• main road - yellow-orange filling, width as Roadway LOD

Colors are defined in (core) cfgUI.hpp:

class CfgInGameUI.IslandMap
colorTracks[] = { 0.35, 0.2, 0.1, 0.8 };
colorRoads[] = { 0.35, 0.2, 0.1, 1 };
colorMainRoads[] = { 0, 0, 0, 1 };
colorTracksFill[] = { 0, 0, 0, 0 };
colorRoadsFill[] = { 1, 0.92, 0.74, 1 };
colorMainRoadsFill[] = { 0.93, 0.11, 0.14, 0.8 };

To view the roads correctly, all their models should contain Named Property map in 1st Resolution LOD or in Geometry LOD. Crossroads should have the property of the road which is higher in hierarchy (e.g. crossroad of main road and track will have map = main road). Named Property map values for the road types:

track
road (used in cases model is class = road but named property "map" is not defined)
main road

Following roads were used on Sahrani (roads.pbo):

• flagged road - kos* - road
• field track - ces* - track
• main tarmac road - sil* - main road
• other tarmac roads - asf* - road
• urban road for cities - silnice_mesto* - main road

Besides the settlement names, it is possible to add more local name types. All such names and symbols are inserted in Visitor using Key Points. Info on key points is stored in MapName.hpp during export of WRP and should be included in map config. Some symbols have icons as well or are used just as icons.

List of key point types:

• Hill - name of hill (mountain) - small black italics and icon
• BorderCrossing - red icon
• VegetationBroadleaf - green icon for broad leaf forest, no name
• VegetationFir - green icon for coniferous forest, no name
• VegetationPalm - green icon for palm grove, no name
• VegetationVineyard - green icon for vineyards, no name
• NameMarine - name for bays, straits, capes, lakes etc., blue italics
• NameCityCapital - big black name for main cities
• NameCity - black names of common cities
• NameVillage - smaller version of city name
• NameLocal - local name, used for islands, natural features, special locations, brown italics
• RockArea - icon of rocky area, same symbol as for single rock object used

Drawing of particular Key Points is defined in config (class CfgLocationTypes.<TypeName>). Following values are used:

• name - user-friendly type name (for use in editor)
• drawStyle - how is it drawn
• name - name without icon, better adaptation to map zoom
• mount - hill - point icon and height
• icon - icon, sometimes with inscription
• area - surface filled by pattern
• texture - texture of icon o filling
• color - colour of texture and text
• size - size of icon (size in pixels in reference resolution 640 x 480)
• font - font used
• textSize - basic text size (proportion of screen height)

Key points are inserted in Visitor 3, their types are listed in file KPtypes.cfg, which is part of Visitor distribution. New types may be added provided they are defined in game/addon configuration.

Icons are assigned to objects based on values of Named Property map.

List of values (class - Named Property):

Tree - TREE
SmallTree - SMALL TREE
Bush - BUSH
Building - BUILDING
House - HOUSE
ForestBorder - FOREST BORDER
ForestTriangle - FOREST TRIANGLE
ForestSquare - FOREST SQUARE
Church - CHURCH
Chapel - CHAPEL
Cross - CROSS
Rock - ROCK
Bunker - BUNKER
Fortress - FORTRESS
Fountain - FOUNTAIN
ViewTower - VIEW-TOWER
Lighthouse - LIGHTHOUSE
Quay - QUAY
Fuelstation - FUELSTATION
Hospital - HOSPITAL
Fence - FENCE
Wall - WALL
Hide - HIDE
BusStop - BUSSTOP
Road - ROAD
Forest - FOREST
Transmitter - TRANSMITTER
Stack - STACK
Ruin - RUIN
Tourism - TOURISM
Watertower - WATERTOWER
Track - TRACK
MainRoad - MAIN ROAD
Rocks - ROCKS
PowerLines - POWER LINES

Icon for each map property is defined in map resources (default in class RscMapControl v rscCommon.hpp). every type has its own subclass named as a type, containing following settings:

• icon - name of icon texture
• color - icon color (multiplied with color in texture)
• size - icon size (pixels with reference resolution 640 x 480)
• importance - decides, which icon is drawn when there are several overlapping icons in one place
• coefMin - how much can icon scale down when zooming out
• coefMax - how big can icon become when zooming in

Icons without assignment to object, inserted only via Key Points, are following:

vegetationPalm
vegetationFir
vegetationBroadleaf
vegetationVineyard
borderCrossing
viewpoint
hill
rockArea

Buildings (property map = building, house and fence) are drawn as bounding boxes, colored by average texture color. For some buildings with special icon, both icon and bounding box are drawn.

Map types, where both icon and box are used:

fuelstation
hospital
chapel
church
tourism 
ruin

Black line is drawn along memory points of power lines objects. Snapping points of models are discarded by binarization, hence they cannot be used. In Memory LOD of power line models are points map1 and map2, between which the line is drawn. Models need to have named property map = power lines.

List of power line objects in Arma:

misc\sloup_vn.p3d - pole
misc\sloup_vn_drat.p3d - wires
misc\sloup_vn_dratz.p3d - wires, diverting 5°
buldings\trafostanica_velka_draty.p3d - wires to power house

Similar as forests. Instead of several objects, light brown semi-transparent polygon is drawn based on density specified in map config. On Sahrani, several big rocky areas were accompanied by KeyPoint icon for rocks.

In map config:

minRocksInRockSquare = N;

Colours are defined in RscMapControl

colorRocks
colorRocksBorder

Polygons around groups.

TreesInForestSquare = N;

Lower the N, more intensive aggregation to polygons.

Colours are set in RscMapControl:

colorForest
colorForestBorder

Runway and taxiway are drawn, both as rectangles based on ILS values in map config. If the taxiway is more complex, rectangle is still drawn. Width of both rectangles is fixed in the engine.

They are drawn according to map terrain. Color of contours is set in central config (RscMapControl) as colorCountLines and colorCountLinesWater. Every 5th contours is drawn bolder, contour interval changes according to map zoom.

It is possible to display surface texture in mission editor of the game. It is cut to squares and stored in map PBO (/Data/Layers/). In the area outside the map, top right square of the set is displayed repeatedly.
