[edit] What can this extension do?

Convert geographical coordinates written in decimal degrees format to degrees format using a parser function. The function only works for N/E locations, but can be easily extended.

This can be especially useful in combination with the Geographic Coordinate attribute type of the semantic mediawiki extension.

[edit] Usage

({{#coordinate:lat|5.6907811760902405° E, 50.851378111532355° N}}, {{#coordinate:lon|5.6907811760902405° E, 50.851378111532355° N}})
