| - | ====== points.xml ====== | ||
| - | |||
| - | 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...) | ||
| - | |||
| - | The ''points.xml'' file is located in the ''fir/'' directory. | ||

| - | |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: | ||
| - | * Z = N or S for latitude, E or W for longitude | ||
| - | * ddd = degrees (3 digits, zero padded) | ||
| - | * mm = minutes (max 59) | ||
| - | * sssss = seconds with maximum 3 decimal places (max 59.999) | ||
| - | |||
| - | ==== latitude / longitude ==== | ||
| - | |||
| - | * lat="N0543000000" → N054:30:00.000 | ||
| - | * lon="W0033535000" → W003:35:35.000 | ||
| - | |||
| - | |||
| - | The following is also valid: | ||
| - | lon="W0033535" → W003:35:35.000 | ||
| - | |||
| - | |||
| - | |||
| - | |||
| - | |||
| - | ==== Example ==== | ||
| - | |||
| - | A point element needs to be defined in the **points.xml** file: | ||
| - | |||
| - | <code XML> | ||
| - | <points> | ||
| - | <point id="COA" lat="N0512053002" lon="E0032119001"/> | ||
| - | </points> | ||
| - | </code> | ||
| - | |||
| - | You can then reference that point in any map, replacing latitude/longitude or cartesian x/y pairs. | ||
| - | |||
| - | <code XML> | ||
| - | <symbol id="vor_symbol" text="COA" color="symbol_vor_color" lat="N0512053002" lon="E0032119001"/> | ||
| - | </code> | ||
| - | |||
| - | could be replaced by: | ||
| - | |||
| - | <code XML> | ||
| - | <symbol id="vor_symbol" text="COA" color="symbol_vor_color" ref="COA" /> | ||
| - | </code> | ||
| - | |||
| - | Another example ... | ||
| - | |||
| - | If you would like to draw a circle around a known VOR beacon ... | ||
| - | |||
| - | <code XML> | ||
| - | <circle radius="10" segments="64" r="255" g="0" b="0"> | ||
| - | <point lat="N0512053002" lon="E0032119001"/> | ||
| - | </circle> | ||
| - | </code> | ||
| - | |||
| - | could be replaced by: | ||
| - | |||
| - | <code XML> | ||
| - | <circle radius="10" segments="64" r="255" g="0" b="0"> | ||
| - | <point ref="COA"/> | ||
| - | </circle> | ||
| - | </code> | ||
