View source for Template:Location map many/doc

Creates a location map as a [[m:Help:composite images|composite image]] of an existing map in [[equirectangular projection]], with multiple (up to 9) markers and optional labels superimposed onto it.  This template functions in the style of [[Template:Location_map]], but allows 9 markers and labels (rather than just one marker).  Note: For brevity, parameters "pos" & "bg" are aliases (for "position" & "background").

: ''Also see:'' For an unlimited list of markers/labels, see: ''[[Template:Location_map+]]'',
: which specifies points as a coded template list of markers/labels.

 <nowiki>}}</nowiki><!-- end of indented parameter notes-->

Parameter ''locname'' refers to {Template:Location map ''locname''} containing the image name and coordinates of a particular map.

When a marker's mark<small>#</small>size=0, then that marker is skipped and only the related label is displayed, without the marker.

== Advisory messages ==
Due to the numerous details of specifying 9 markers/labels, the latitude and longitude are checked to lie within the actual map limits specified in ''Template:Location_map_<parameter1>''.  Each marker/label is checked and can list a message (under the map), such as:
:::: Latitude#4 (45.68) < map min(53.74).

Processing continues, with that marker actually placed off-map, and all latitude/longitude parameters are checked, for a total of 18 possible advisory messages.  Only degrees of latitude/longitude are checked, so a value of 63 minutes would be valid to indicate 1 extra degree + 3 minutes, and setting lon_min=200 could still place a marker off-map (right-side) with no warning.  Also, large markers or long labels can spill over the edges of a map, allowing markers to point inward from outside the map.  In such cases, a map could be centered by itself on the page ("float=center") to avoid overlapping the edge markers onto any surrounding article text.

== Available maps ==

List of live templates named ''Template:Location_map_<locname>'' (without "Template:" prefix here):
{{Special:Prefixindex/Template:Location_map_}}

== Creating new maps ==

#Find an appropriate blank map in [[equirectangular projection]] (otherwise, coordinates will drift off, typically further north)
#Create a template named "Template:Location_map_''locname''" (copy the content of any other map template into it and enter appropriate values).
#Set default parameter values (using those parameter names), such as setting "mark" with image-file name and "marksize" for pixels wide/tall, or set default label font size ("label_size = 78" percent).
#Parameter names not used by "[[Template:Location_map]]" will be ignored by it, and only used for multiple-markers (such as defaulting "label2_size = 78" percent, or "mark2size=7" pixels).

==Implementation notes==
The map with markers/labels is implemented as nested HTML divisions. The map-image is in an HTML division, containing each point as a percent-locator division containing a marker-image sub-division plus a label sub-division.  Each point is calculated (for a percent-locator division) with X or Y coordinate "XX.X%" or "YY.Y%" as follows:

* The div-tag is "&lt;div style="position: absolute; z-index: 2; top: XX.X%; left: YY.Y%; ...&gt;"
* For placing latitude, the calculation is:
:* XX.X% = 100 * (top - (lat_deg + latmin/60 +latsec/3600) ) / (top - bottom)
:* If lat_deg is empty, the combined decimal latitude is used from "lat".
:* If lat_dir is "S" (south), the latitude is multiplied by -1.
:* (Note latitude is positioned in reverse, from top of map downward.)
* For placing longitude, the calculation is:
:* YY.Y% = 100 * ( (lon_deg + lonmin/60 +lonsec/3600) - left ) / (right - left)
:* If lon_deg is empty, the combined decimal longitude is used as "long".
:* If lon_dir is "W" (west), the longitude is multiplied by -1.
* The div-tag is ended as "height: 0; width: 0; margin: 0; padding: 0;"&gt;".
* Within that division the marker/label sub-divisions are coded as:
:* &lt;div style="position: relative text-align: center; ..."&gt;.
* For label position, the options are shifted as:
:* when position=left, adds "left: -6.5em; text-align: right;"
:* when position=right, adds "left: 0.5em; text-align: left;"
:* when position=top, adds "top:-2.65em; left:-3em; text-align: center;"
:* when position=bottom, adds "top:-0.15em; left: -3em; text-align: center;" to div-tag.
