ClubWiki:Using GMaps

This wiki site uses a MediaWiki extension called Maps. It's full syntax description can be found at its home site. Here we will just describe the basic features typically used for this site for simplicity for our users

Basic use

The map is invoked by using the following basic structure

<display_map options and KML links>
(optional and multiple possible) pin locations
</display_map>

This site prefers that routes/trails are kept in the KMLs and the pins/markers are specified within the wiki markup on the page. By keeping the pins specified in the wiki markup, it is easier for users of this site to add/remove/modify them.

The specifics of each portion are explained below

Extension options

Available coding options are (full list here):

• center (location which can be coordinates or place name but place names slows page render; default is centered on all listed pins)
• width (assumes pixels by default but can also be ex, em, %; default is auto)
• height (assumes pixels by default but can also be ex, em, %; default is 350)
• zoom (the zoom level; 0 is the furthest away, 21 is the closest in; 15 is closest zoom for terrain)
• type ("terrain" or "roadmap", "hybrid", or "satellite"; default is "roadmap")
• controls (controls to place on the map, list any/all pan, zoom, type, scale, streetview)
• zoomstyle (not sure yet, but I think we want this for small vs. large maps)
• typestyle (not sure yet, but I think we want this for small vs. large maps)
• kmlrezoom (yes/no center on drawn kmls; default is no)
• gkml (list URLs to kmls separated by a comma)
• markercluster (automatically groups crowded pins and zooms on click; default no)

All attributes are optional. If it is not specified the above described default will be assumed.

So the final code to place just a map with no other features might be:

<display_map center="Warriors Path State Park, TN" zoom="12" width="50%" height="200" type="terrain" controls="scale,type">
</display_map>

KML files

KMLs are now specified within the open command. Using the kml (not sure when this is used) or gkml (the one we seem to need to use) you can add URL(s) that point to KML files. Each URL should be separated by a comma.

<display_map gkml="http://tehcc.org/clubwiki/kml/Pinnacle_Mountain_Tower_Trail.kml,http://other.url/,...">
</display_map>

These files will be dynamically imported into the map each time the map is loaded. For now, any new KMLs must be emailed to the webmaster for uploading to the site. These are kept in the above referenced (tehcc.org/clubwiki/kml) folder. Another warning is to avoid spaces in the KML title as these will not properly link, so use underscores or hyphens to connect the words.

Pins

Pins are added by using the following syntax within the <display_map> tags. The different attributes of the pin are separated by tildes (~).

Location~Title~Details~Icon~Label~Visited Icon
location~balloon title~balloon contents~URL or image reference for pin icon~something else~label(shows next to pin at all times)~URL or image reference to visited pin

Full coding showing two pins, the first with a linked title and regular text with a persistent label and the second with no linked title but regular text and a small image:

<display_map center="36.500667,-82.47797" type="terrain" zoom="15" width="715" height="350">

The above commands can be used many times within a single map to create the pins needed. Note that each pin must end with (;) except the last one

Pin icons

Icons can be changed by two methods, changing all undefined icons to a specified one or invoking the custom icon list used on this site and then specifying pin by pin which icon to display for the pin

Default Pin Icons

The default icon used for pins can be changed by adding an icon command in the extension options:

1. Add the icon address in quotes to the googlemap tag, using icon:

<googlemap lat="36.072635" lon="-79.791975" icon="http://images.wikia.com/walkingdead/images/7/70/Markerfight.png">

Full coding example:

<googlemap lat="36.072635" lon="-79.791975" icon="http://images.wikia.com/walkingdead/images/7/70/Markerfight.png">
38.453857, -84.356461, Rick Grimes Shot
</googlemap>

Custom icons

This site has a list of custom icons that can be used. See the #Icons reference to know which letters will invoke which icon

1. Add the following extension icons option:
   1. <googlemap lat="36.500667" lon="-82.47797" icons="http://tehcc.org/clubwiki/kml/marker{label}.png">
2. Prefix the pin coordinates with (X) where 'X' is the letter for the pin icon desired
   1. (G) 36.502891,-82.468700
