This map definition, Template:Location_map_100x100, is intended for overlaying markers/labels on any specified image, using map coordinates ranging from 0-100.0 for latitude or longitude. See the technical design below, under:
All mapping templates use similar parameters (see Examples):
Some common label background colors are: #CCCC55 for
dim yellow,For small lettering use label_size=80, for tiny words use 55. Note that the words in the label will wrap unless using "nbsp": DO NOT WRAP.
When specifying image "width=270" be sure to OMIT "px" (which causes the image to span the width of the screen) because "px" cannot (yet) be detected by the (new) MediaWiki language which processes those mapping templates.
See each specific mapping template for other parameters to pass.
{{Location map | 100x100 | caption = Example on blank image | width=250 | label=You are Here | label-size=90 | background = #DDDD44 | position=bottom | lat = 55.00 | long = 22.35 | mark=Green_pog.svg | marksize=10 | float=right }}
{{Location map | 100x100 | AlternativeMap = Gold star on blue.gif | caption = Marker on star | width=110 | label=Dot | label-size=80 | background = #CCCCCC | position=left | lat = 81.00 | long = 42.90 | mark=Red_pog.svg | marksize=8 | float=right }}
It is possible to place markers/labels outside a map, by specifying latitude or longitude coordinates beyond 0-100.0:
For templates that restrict coordinates, expand the minutes field: lat_deg=100.0 but lat_min=120 yielding a combined 102 degrees (60 minutes = 1 degree).
