KML Layers

2 methods:

• Live feed
• File upload

Cache feeds so that if Internet goes down they remain available.

Styling/Features example:

• ​http://crschmidt.net/mapping/kml

Need to handle network links.

Need to unzip KMZ files, which requires intercepting the uploaded file before just saving to the DB: ​http://groups.google.com/group/web2py/browse_thread/thread/63809c06cac3b0d5

Need to catch a folder full of Network Links inside the Network Link!

We wish to display internal Features using KML feeds too (to avoid extra work).

• Control URL parameters from jQuery controls: ​http://fuzzytolerance.info/code/using-geoserver-openlayers-and-cql-filters/
• Popup content advanced options: ​http://www.mail-archive.com/users@openlayers.org/msg11117.html
  • Different content for Hover (e.g. Title) & CLick (full HTML)
  • Load dynamically via AJAX

OpenLayers doesn't yet support GroundOverlay & ScreenOverlay:

• ​http://trac.openlayers.org/ticket/1567

NB This is separate to the KML Import/Export

CSV to KML Converter
