Extension:Google Maps/Syntax

In many cases you can get by using the Editor's Map, but understanding the underlying coding of the Google maps extension will unlock a few extra features for you.

Extension options
Available coding options are:


 * width (in pixels; default is 740)
 * height (in pixels; default is 600)
 * lat (the center latitude on the map)
 * lon (the center longitude on the map)
 * zoom (the zoom level; 0 is the furthest away, 21 is the closest in)
 * type ("normal" or "map", "hybrid", or "satellite"; default is "hybrid")
 * controls (small creates +/- zoom buttons, medium has zoom buttons and pan buttons, large has pan buttons with a sliding scale for zoom, and none has no buttons)
 * selector (show the map/hybrid/satellite selector? yes (default) and no.)
 * scale (show the distance scale? yes and no (default).)
 * overview (show the inset navigation map? yes and no (default).)
 * icons (web address if the marker icon is customized. With "{label}" where the name of the icon will be inserted; defaults to " http://maps.google.com/mapfiles/marker{label}.png ")
 * icon (web address if the marker icon is not specified; the default icon is http://maps.google.com/mapfiles/marker.png)
 * units ("meters" or "miles"; default is "meters".)

All attributes are optional.

So the final code might be:

 52.499683,13.333907,Kaiser Wilhelm Memorial Church 52.510019,13.369893,Berlin Philharmonie

Icons

 * See Mapki's collection of icon images for a several icons you can use.

You can create your own collection of icons (markers) on your server.

1. Upload a picture which will serve as the icon to your wiki. With the name marker(name of icon).png. For example, markerfight.png to create the "fight" marker.

2. Click the uploaded picture so only the picture is showing on the web page. For example, http://images.wikia.com/walkingdead/images/7/70/Markerfight.png

3. Add the icon or icons coding in quotes the googlemap tag, To make a custom icon, use icons: 
 * To change the red Google default icon, which will always appear unless you indicate a customized icon in parenthesis, use icon:

Using in a template
If you would like to put a map inside a template, then you will need to use a slightly different coding to get the coding to work properly.

The following is an example for including a map without markers.

BAD:



GOOD:

This #tag technique only works with MediaWiki 1.12 and later.

if the above does not work, try

KML export
Beginning with version 0.9.0, there is a new tag called. This will export all of the maps on the current page to a KML file. The contents of the tag are the contents of the link, for example:

Download KML

To export the KML from another article, just use the "article" attribute, e.g.

Download KML

KML import - export
It is possible to merge the maps of some other articles within a new article’s map, but you must use the full url of GoogleMapsKML.

http://your.wiki.url/index.php?title=Special:GoogleMapsKML&article=a_article http://your.wiki.url/index.php?title=Special:GoogleMapsKML&article=another_article ...

Map coding version "0" (default)
This section describes the "old coding", which is enabled by default. To force its use, set  in the map attributes.

Markers
In the content of the tag, you can define one marker per line.
 * Each line can optionally start with an icon name in parentheses; unless you set the "icons" attribute, icon names are the upper-case letters of the alphabet. example: (S)
 * the latitude, then a comma, optionally a space, example: 42.711618,
 * then the longitude, then a comma, example: -73.205112,
 * then the text for the pop up information balloon. The label can include wiki coding (and commas) example: The fabulous, famous Sawyer Library 

For example:

 42.711618,-73.205112,the fabulous, famous Sawyer Library 42.711618, -73.205112, the fabulous, famous Sawyer Library (S) 42.711618, -73.205112, the fabulous, famous Sawyer Library

Paths
This feature must first be enabled on your wiki; see Extension:Google Maps/Installation

To connect multiple points with a colored path, start the line with a color in RGB hex format., for example:

42.711618,-73.205112 42.714779,-73.204544
 * 1) 330000

This will connect the two points with a colored line. Any points not on a line should appear before all points on lines. For example:

42.711618, -73.25112, this point is not on a line 43.224024, -70.28301, neither is this one 42.202452, -72.83101, this is on a line of color #77077 45.214425, -72.48114, so is this 42.201324, -70.95811, this starts a second line 43.404142, -73.44514, this is also on the second line Any text on the same line as, but appearing after, the color specification will be ignored.
 * 1) 770077
 * 1) 668800

You'll probably want to use the Extension:Google Maps/Editor's Map to generate this coding.

Areas
New in 0.8

Areas are enclosed paths with a colored filling. The coding is just like a path, except that the interior color should be specified in parentheses after the path color, like this:


 * 1) 770077 (#668800)

Tabs
New in 0.7

A feature new to 0.7 are tabbed info balloons. Each tab should have a plain-text title surrounded by inward-leaning slashes (like /this\) followed by a caption that can include wiki mark-up. Tabs will be attached to the previous marker. Example:

45.214425, -72.48114 /Info\       This is where Ulysses Grant is buried /Directions\ Click here to get driving directions

That will create a point whose info balloon has two tabs. Note that you can put as much or as little space as you'd like between the title and the caption to make the coding more readable.

If a point has a regular caption and tabbed captions, clicking the point will only show the tabbed captions.

Map coding version "0.9"
Starting with release 0.9.0, a new map coding is available. It differs only slightly from version "0". To use the new coding, you will need to set  in the map attributes (the Editor's Map will do this for you). Benefits include:


 * Multiline captions
 * Specify opacity
 * Titles that appear on mouse-over

The new coding is described below.

KML import
Before you specify any markers, you can add URLs that point to KML files. Each URL should be on its own line, e.g.

http://some.url/ http://other.url/ ...

These files will be dynamically imported into the map each time the map is loaded.

Markers and Tabs
Markers can be specified in several ways:

No caption, just a point: 42.711618, -73.205112

A marker labeled "S": (S) 42.711618, -73.205112

A title but no caption. The title can NOT contain wiki markup. It is displayed when a user mouses over the marker: 42.711618, -73.205112, Sawyer Library

Title plus a caption. The caption appears when a user clicks on the marker: 42.711618, -73.205112, Sawyer Library Sawyer Library, built in 1977

A caption can span multiple lines. However, the title is still optional, so this is okay too:

42.711618, -73.205112 Sawyer Library, built in 1977

Finally, you can also create tabs. A tab's title should appear between inward facing slashes(/ and \). The content of a tab should be on a new line and can span multiple lines, just like captions.

latitude, longitude, title /tab1\ caption1 /tab2\ caption2 ...

Paths and Areas
You can connect multiple points with a color line. However, in version 0.9.0., the color must now include opacity and width information, for example:

6#FF330000

In the example above the width is 6 pixel's wide, the opacity is #FF (opaque) and the color is #330000.

The 6 means that the path will be 6 pixels wide. The first two hex digits specify the opacity from #00 (transparent) to #FF (opaque). The final 6 hex digits are a "web color", for example #RRGGBB.

Similarly for areas, the interior color should be 8 digits instead of 6; the first two digits define the opacity, for example:

6#770077 (#BB668800)
