This template displays a location map as a [[m:Help:composite images|composite image]] of an existing map plus a marker and an 
optional label superimposed onto it. Maps used here are not just images alone. Instead, maps are selected by mapper-template suffixes "XX" (to use template "Location map XX"). Maps can be defined either as ''squared'' for [[equirectangular projection]]s or else, have curved [[عرض جغرافیایی]] or [[طول جغرافیایی]] lines, to skew the location of the marker symbol, as in {{tl|Location map Africa}}. That mapper for Africa uses [[sine]]/[[cosine]] factors to shift the marker x/y to fit the curved lines. Each mapper template sets its own map borders and decides if skewing x/y for curved lines. See the technical design below, under "[[#Design issues|Design issues]]".

'''Note:'''
* Setting caption=xxxxx also frames the map, while an empty "caption=" leaves the map unframed.
* The coordinates are not checked. If the coordinates fall outside the map, then the marker will try to appear outside the map-image, overlaying the page text.
* For a map with no marker, set marksize=1.
* Do not use "px". Using width=200px causes maps to cover a page, use: width=200 (no "px").
* To create a map with more than one marker, refer below to: [[#See also|See also]].
* To display a map that uses a non-equirectangular projection (i.e. has curved [[عرض جغرافیایی]] or [[طول جغرافیایی]] lines), use skew factors for x/y as in {{tl|Location_map Africa}} or try [[Template:Location map skew]].
