Module:Coordinates: திருத்தங்களுக்கு இடையிலான வேறுபாடு

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.

{{#Invoke:Coordinates | link }} : Export the link used to reach the tools

Determine the required CSS class to display coordinates

Usually geo-nondefault is hidden by CSS, unless a user has overridden this for himself

default is the mode as specificied by the user when calling the {{coord}} template

Wrapper to allow templates to call dec2dms directly.

is appended (typical N or E), if negative, the negative suffix is appended. The

Converts DMS values specified as degrees, minutes, seconds too decimal format.

direction_flag is one of N, S, E, W, and determines whether the output is

positive (i.e. N and E) or negative (i.e. S and W).
