Problem statement:

Ushahidi’s community map data should be interoperable and open. We want to make it easier to share and use data sets between the various mapping communities.

We fixed the CSV upload/download in core, which is admin only, for Crowdmap/ Ushahidi 2.6
The plugin is the same as always. Though there is a new version called downloadreports which also supports KML ( a bit limited output though )
