Module:Coordinates
Documentation for this module may be created at Module:Coordinates/doc
--[[
This module is intended to replace the functionality of {{Coord}} and related
templates. It provides several methods, including
{{#Invoke:Coordinates | coord }} : General function formatting and displaying
coordinate values.
{{#Invoke:Coordinates | dec2dms }} : Simple function for converting decimal
degree values to DMS format.
{{#Invoke:Coordinates | dms2dec }} : Simple function for converting DMS format
to decimal degree format.

coord
Main entry point for Lua function to replace {{coord}}
Usage:
{{ Invoke:Coordinates | coord }}
{{ Invoke:Coordinates | coord | lat | long }}
{{ Invoke:Coordinates | coord | lat | lat_flag | long | long_flag }}
...
Refer to {{coord}} documentation page for many additional parameters and
configuration options.
Note: This function provides the visual display elements of {{coord}}. In
order to load coordinates into the database, the {{#coordinates:}} parser
function must also be called, this is done automatically in the Lua
version of {{coord}}.
