____ OpenStreetMap Plugin ____
|
||||||
|

|
||||||
|
|
||||||
|
This addon allows you to use OpenStreetMap for displaying locations.
|
||||||
|
|
||||||
|
___ Requirements ___
|
||||||
|
|
||||||
|
To use this plugin you need a tile Server that provides the maps.
|
||||||
|
OpenStreetMap data is free for everyone to use. Their tile servers are not.
|
||||||
|
Please take a look at their "Tile Usage Policy":
|
||||||
|
http://wiki.openstreetmap.org/wiki/Tile_usage_policy
|
||||||
|
You can run your own tile server or choose one from their list of public
|
||||||
|
tile servers: http://wiki.openstreetmap.org/wiki/TMS
|
||||||
|
Support the OpenStreetMap community and share the load.
|
||||||
|
|
||||||
|
___ Configuration ___
|
||||||
|
|
||||||
|
Open the .htconfig.php file and add "openstreetmap" to the list of activated
|
||||||
|
addons.
|
||||||
|
$a->config['system']['addon'] = "openstreetmap, ..."
|
||||||
|
|
||||||
|
You have to add two configuration variables for the addon:
|
||||||
|
$a->config['openstreetmap']['tmsserver'] = 'http://www.openstreetmap.org/';
|
||||||
|
$a->config['openstreetmap']['zoom'] = '18';
|
||||||
|
|
||||||
|
The *tmsserver* points to the tile server you want to use. Use the full URL,
|
||||||
|
with protocol (http/s) and trailing slash. You can configure the default zoom
|
||||||
|
level on the map with *zoom*. 1 will show the whole world and 18 is the highest
|
||||||
|
zoom level available.
