Getting layers to work on Ushahidi is a constant community discussion. This wiki article is to write about what works, what needs work and what to expect. Ushahidi uses Open Layers at the moment. We have some team members playing with Leaflet too.

There are a number of tickets open about layers. The biggest user of layers is the Standby Task Force.  The purpose of this page is to help better define the issues and hopefully resolve it.

Layers and Crowdmap

Crowdmap allows for KML file uploads as "Layers" on our map -- Layers are contextual information available as an overlay to the reports.  If organizations are looking to import data points from KML files act active reports within Ushahidi, that is not an option.  The CSV format is currently our only option for that.

WMS Layers

What is it?

"A Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the Internet that are generated by a map server using data from a GIS database"

How does it work?

WMS is currently only supported through custom code. There's no UI for add WMS baselayers or overlays in Ushahidi yet.

WMS as alternative to KML: Rather than importing an overly complex KML direct to Ushahidi. If you run a WMS server, such as geonode, you can import the source data (ie. shape files) and convert it to whatever format you need: KML or WMS.

KML Layers

What is it?

KML is an XML based format for geographic data, most notably used by Google Maps and Google Earth. More info:

How does it work?

Support for KML layers is built in to Ushahidi core. This allows you to add KML layers from an uploaded file or URL and overlay them on your map.
However this is based on Openlayers KML support and so has some limitations.
