Template:Location map many/doc

From 'City of Adelaide' History and Genealogy Site
Jump to navigation Jump to search

Creates a location map as a 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.

}}

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

When a marker's mark#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):

Creating new maps

  1. Find an appropriate blank map in equirectangular projection (otherwise, coordinates will drift off, typically further north)
  2. Create a template named "Template:Location_map_locname" (copy the content of any other map template into it and enter appropriate values).
  3. 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).
  4. 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 "<div style="position: absolute; z-index: 2; top: XX.X%; left: YY.Y%; ...>"
  • 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;">".
  • Within that division the marker/label sub-divisions are coded as:
  • <div style="position: relative text-align: center; ...">.
  • 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.
