| ==== Example ==== | ==== Example ==== | ||
| + | |||
| + | A point element needs to be defined in the **points.xml** file: | ||
| <code XML> | <code XML> | ||
| <points> | <points> | ||
| - | <point id="REMBA" lat="N0503944000" lon="E0045451000"/> | + | <point id="COA" lat="N0512053002" lon="E0032119001"/> |
| </points> | </points> | ||
| </code> | </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> | ||
