Template:Location map Russia (equirectangular) is a location map definition used to overlay markers and labels on an equirectangular projection map of روسیه. The markers are placed by عرض جغرافیایی and طول جغرافیایی coordinates on the default map or a similar map image.
Usage ویرایش
These definitions are used by the following templates when invoked with parameter "Russia (equirectangular)":
{{Location map|Russia (equirectangular) |...}}{{Location map many|Russia (equirectangular) |...}}{{Location map+|Russia (equirectangular) |...}}{{Location map~|Russia (equirectangular) |...}}
Map definition ویرایش
- name
- used in default map caption (روسیه)
- image
- the default map image, without "Image:" or "File:" (Russia location map.svg)
- x
- an expression to calculate a location on the map via its طول جغرافیایی; evaluates as 0 along the left edge and 100 along the right edge
- y
- an expression to calculate a location on the map via its عرض جغرافیایی; evaluates as 0 along the top edge and 100 along the bottom edge
Technical details ویرایش
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 | 81.8 | 19.6333 | (0,-0) | (0,0) |
| top/right | 81.8 | -169.667 | (100,-0) | (100,0) |
| bottom/left | 41.19 | 19.6333 | (0,100) | (0,100) |
| bottom/right | 41.19 | -169.667 | (100,100) | (100,100) |
| center | 61.495 | 104.98315 | (50,50) | (50,50) |
