XML Gauge Maps

The following table of variables can be used within the XML Gauge system to create colored 2D maps, such as those that appear in GPS or radar systems. Refer to the Creating XML Gauges document for more details on creating XML gauges.

2D Map Drawing

The 2D map is rendered in the following order. The order cannot be changed, but whether each layer is rendered or not, the colors used, and a number of other features of the map, can be changed through the setting of the various variables.

  1. Background
  2. Terrain
  3. Geo-political
  4. Grid lines
  5. Range rings
  6. Airports
  7. VOR
  8. NDB
  9. ILS
  10. Intersections
  11. Airspace
  12. Flight plan
  13. Approach data
  14. Vehicles
  15. Airways
  16. Racepoints

The compass rose is a separate object in the gauge system, but is drawn on top of the radar screen.

XML Map Variables

Most of the following variables can only be used by the map gauge itself. Three can be read by other gauges: TagPosition, SelectedVehicle and MapLoading. The first two, TagPosition and SelectedVehicle, can also be set by other gauges.

Priority Bool Set to True to draw the map as a priority.
Zoom Float Range of 80 to 500000 pixels per meter. Default is 5 x 1852 (1852 is meters per nautical mile).
PanVertical Float Distance to pan vertically in pixels. Negative will pan up.
PanHorizontal Float Distance to pan right in pixels. Negative will pan left.
PanReset Bool Set to True to return to the original position prior to any panning.
MapLoading Bool Set to True if the map is currently being loaded.
Latitude Float The latitude that is to be the center point of the map (usually the user aircraft, though could for example be an airport tower).
Longitude Float The longitude of the center point of the map.
Heading Float The heading (usually of the user aircraft).
TrackUp Bool Set to True if the map should be drawn with the track of the aircraft facing up. False gives North facing up.
CenterX Float The X position of the aircraft (usually the user aircraft, but could for example be an airport tower) on the map, in pixels. This is often the actual center of the map, but can be used so that more of the map shows what is in front of the aircraft, and less behind it.
CenterY Float The Y position of the aircraft on the map, in pixels.
UpdateAlways Bool Set to True if the map should be updated every frame. Set to False if the map is only to be updated when positions have changed enough.
SelectedVehicle Int The ID of the selected vehicle. Refer to the ITrafficInfo custom variables described in the Creating XML Gauges document for more details.

XML Compass Rose Variables

Heading Float The heading of the compass.
CenterX Float The X position of the center of the compass on the map.
CenterY Float The Y position of the center of the compass on the map.
Radius Float Radius of the compass in pixels.
Color Int RGB value of the compass lines and text.
BackgroundColor Int RGB value. The default, if no color is set, is transparent (so an underlying map will be visible).
LineWidth Float Compass line width in pixels.
Font String The font to use for the compass labels. If no font is specified "Arial" is the default.
FontSize Float Font size for compass labels.
BigFontSize Float See LabelAllTicks.
FullCircle Bool Set to True to ensure compass rose is a full circle. False indicates that an arc will be rendered.
LabelAllTicks Bool Set to True to ensure a label on every tick mark (every 10 degrees). False indicates that labels should be every 30 degrees, and the main four compass points are marked with letters ("N","S","E","W") rendered in the BigFontSize.
Force3Digits Bool Set to True to force three digits per compass label (see the example image below).

Example Map

The view an example map, navigate to the C:\Program Files\Microsoft ESP\1.0\Gauges\radar.cab folder, right click the radarscreen.xml file, and extract it. Refer to the following notes when examining the code:

  • The Script entry of the Update object is simply initialization code. Cut and paste scripts into the Infix tool to convert them to infix notation to make them much easier to understand. The Infix tool is in the Panels and Gauges SDK folder.
  • The use of a small set of macros makes the coding simpler, and provides a single line to change if the radar screen's width or height are to change.
  • The Name parameter of one of the CustomDraw objects is "fs9gps:1:map". The ":1" is unnecessary if the panel in which the map is to appear has only one map. Otherwise use ":1", ":2" and so on to distinguish the different maps.
  • The Name parameter of one of the CustomDraw objects is "fs9gps:rose".
  • The id parameters can be any text that helps identify the object. It is the Name parameter that must match the variable names in the table above.

To view the radar screen in the simulation take the role of a Tower Controller in a multi-player session. The image below shows the radar screen. Note the Radar Settings gauge has communicated to the radar screen, through the use of local variables, that a compass rose should be shown, along with airports, VORs, and terrain. The blue line is a national boundary.
