| - | ====== 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...) | ||

| - | 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 example ==== | ||
| - | |||
| - | * lat="N0543000000" → N054:30:00.000 | ||
| - | * lon="W0033535000" → W003:35:35.000 | ||
| - | |||
| - | |||
| - | The following is also valid: | ||
| - | lon="W0033535" → W003:35:35.000 | ||

| - | <code XML> | ||
| - | <points> | ||
| - | <point id="REMBA" lat="N0503944000" lon="E0045451000"/> | ||
