A viewlet for Plone that show up a Google Maps using the document location field. Also can handle KML files using related contents.

Project description


Monet Citypass preview

Every Plone content can now display a Google’s Map inside a viewlet. In the simpler use case the map is centered on a valid address that Google Maps service can understand (like “Piazza Grande, Modena, Italy”) taken from the content’s “Location” field.

The viewlet is placed (by default) below the content, but your custom theme can move it where you want.

To finally enable the map you need also to access a new option under the “Action” menu. Use this same menu for disabling the map. Remember that a map is displayed only if there is a geolocation to display; if not, a user with the proper permission only see a warning message while other users don’t see anything.

Advanced use

Geolocation fieldset

When you mark a content as “map enabled”, you will see a new “Geolocation” fieldset when you edit it.

From this fieldset you can customize some map behaviors, like:

  • you can choose to point the map onto a different point that isn’t the content “Location” field (maybe still keeping the Location as the displayed baloon info).

  • you can set the starting zoom level of the map

  • you can choose to display or not the baloon on the marker, or display a custom text that isn’t the Location

If you don’t provide an official Location but only the alternative Geolocation and choose to display the location info, the displayed address will be reverse-geocoded, to display a human readable information.

Maps dependency

Starting from version 0.6, the product needs Maps as dependency. A lot of configuration procedures (like put a valid Google Key) are now left to Maps itself. Please refer to its documentation.

In this way we also use the location field and widget for choose a geolocation directly using Google Maps.

Finally, a content that is “map enabled” and were you choosed a geolocation from the new field, can be used as a Maps GeoLocation content (in Folder or Collection “Map view”).

View of the menu entry


Also you can handle KML file using again the Google APIs. You must simply add Plone files with KML extensions to the related contents section of a document where the map is enabled.

When you have KML data to show, you can also use a new portlet that will help users to enable/disable single KML data from the map. The portlet must be enabled where you prefer like every other.

Other dependencies

Tested on Plone 3.3 and 4.1 with Products.Maps 2.1.1

TODO and know issues

  • think about moving KML files away from using related contents and into the new geolocation fieldset

  • make the Products.Maps dependency optional while keeping all other features

  • find a more elegant way to fix issue #35 of Maps

  • find how to fix a bug for using the LocationWidget on Firefox (see also Maps issue #36)

  • some geolocation fieldset’s elements are not translable (seems they are using the plone domain)

Other products

If you need something more professional, pluggable and modular (also with KML support) don’t miss the collective.geo suite! We suggent you to evaluate this suite for a modern Plone 4.0 and 4.1 environment. Still, Monet Maps Viewlet is Plone 3 compatible.
