The points.xml file is used define fixed point elements which can be used in maps instead of <point> elements based on latitude/longitude or cartesian x,y coordinates. These are especially useful when drawing airways or specific procedures based on waypoints (sid, star, loa information, etc…)
(See also Point references)
The points.xml
file is located in the fir/
directory.
Element | point | |
---|---|---|
Attribute | Format | Remarks |
id | string | Identification of the predefined point |
lat | string | latitude value |
lon | string | longitude value |
or
Element | point | |
---|---|---|
Attribute | Format | Remarks |
id | string | Identification of the predefined point |
x | float | cartesian X value in nautical mile |
y | float | cartesian Y value in nautical mile |
If cartesian X/Y attribute values are used, the point is calculated using the <origin> given in the FIR configuration file (config.fir). The format of the latitude/longitude values is Zdddmmsssss where:
The following is also valid: lon=“W0033535” → W003:35:35.000
<points> <point id="REMBA" lat="N0503944000" lon="E0045451000"/> </points>
Use predefined point elements in **points.xml** for often used coordinates in map drawing to make your map files more readable.
