-----------------------------------------------------------------------------------------------------------------
Key: GEOS-3608
URL: http://jira.codehaus.org/browse/GEOS-3608
Project: GeoServer
Issue Type: Improvement
Components: Google Earth KML Output
Reporter: Damian Bradley
Assignee: Andrea Aime
The current Google Earth API now allows users to create HTML String and HTML DIV balloons which would give users the ability to add advanced, and complex functionality into their google mashup popups.
See the Google documentation on these balloons:
http://code.google.com/apis/earth/documentation/balloons.html
I have suggested that similar to the existing "desctiption.ftl" method of adding a description to the balloons. One could add a similar ".ftl" file containing valid HTML code (with Javascript, CSS, etc) into the featuretype directory. Ideally freemarker parsed variables could still be used in this context to allow for easy access to database properties.
The functionality gained by this feature could be wide reaching. Some examples:
- Addition of new media types to balloons (Flash video, QTVR/Panoramas WITHIN the balloons, etc)
- We could use javascrpt to actually control google earth from within the balloons (enable or disable layers, create interactive tours, etc).
- Without the limitations of the HTML subset used in the feature popups, we could design the popup HTML more efficiently and with more complexity
