- | ====== Point References ====== | ||
- | |||
- | The **point.xml** file contains pre-defined points which can be referenced by their **id** in **<point>** elements. This makes maintenance of coordinates much simpler and significantly improves the readability of your map files. Especially when visualizing airways, SID, STAR or any other procedures. | ||
- | |||
- | |||
- | |||
- | 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> | ||
