This template is used to set up an place data page.
Generally speaking, these will be set up as Data namespace pages by periodic automated imports of data extracted from the game client, so it isn't recommended that you set these up yourself. You may want to edit them to update outdated data from time to time, though. Note, though, if imports are consistently adding incorrect information to a data page, you should instead use the appropriate parameters on {{Place}} (correct template?) on the content page instead.
This template shows the data in a table like the one above automatically when used on pages in the Data namespace, but shows nothing when used elsewhere. This is because the data page is transcluded on its content page. The show_data parameter is provided if you want to test data pages in your userspace, though. Setting that to yes will cause it to display the table.
Usage:
{{Place data
|show_data=yes or no
|name=name of the place
|description=place's description
|director_map=filename for the map image
}}
