Template documentation[view] [edit] [history] [purge]

Template:Location map Russia Chukotka Autonomous Okrug is a location map definition used to overlay markers and labels on an equirectangular projection map of the Chukotka Autonomous Okrug in ರಷ್ಯಾ. It is used by "Template:Location map" when invoked with parameter "Russia Chukotka Autonomous Okrug": {{Location map | Russia Chukotka Autonomous Okrug | ...}}. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.

Technical details

For a map using an equirectangular projection which does not cross +/-180 longitude, or +/-90 latitude, the following expressions can be used:

x = 100*(long - left)/(right - left)
y = 100*(lat - top)/(bottom - top)

where lat and long are the degrees latitude and longitude respectively. Here, top and bottom are the degrees latitude of the top and bottom edges of the map, left and right are the degrees latitude of the left and right edges of the map.

Things are a bit more complicated when the map crosses +/-180 longitude, and some sort of "modulo arithmetic" is required. Here, we add 360 if the longitude is less than 0, then use a mapping based on positive coordinates. The following table can be used to check if the expressions are working as desired:

location	lat	long	(x,y) test	(x,y) exact
top/left	73	157	(0,-0)	(0,0)
top/right	73	-167	(100,-0)	(100,0)
bottom/left	61	157	(0,100)	(0,100)
bottom/right	61	-167	(100,100)	(100,100)
center	67	175	(50,50)	(50,50)
