+Aerial Imagery (includign Satellite) can be used as a base layer in Sahana.
+
+The easiest services to use are Google and Bing as they don't require you to host anything yourself.
+
+== Google ==
+This is the easiest to use as it doesn't require the use of an API key.
+
+There are Satellite & Hybrid layers avaialble, as well as the !MapMaker Hybrid and also a 3D Google Earth plugin.
+* these latter require an API Key: {{{settings.gis.api_google = ""}}} [!ToDo: Test these out with current Google APIs]
+
+== Bing ==
+You need to add the [http://www.microsoft.com/maps/create-a-bing-maps-key.aspx API Key] to your {{{models/000_config.py}}}:
+{{{
+settings.gis.api_bing = ""
+}}}
+
+You can check the coverage of Bing Imagery in the area that you're interested in here:

+
+== !OpenAerialMap ==
+This project is trying to restart as it now has some funding to do so:

+
+== Custom ==
+If you have your own imagery then you can provide tiles to Sahana as either TMS or XYZ. WMTS support would be easy to add if-required.
+
+Tiles could be built / served by loading one or more GeoTIFFs into !GeoServer and serve as WMS or TMS with !GeoWebCache:
+* http://docs.geoserver.org/stable/en/user/webadmin/tilecache/defaults.html#gwc-provided-services
+
+A similar workflow could be done with !MapServer.
+
+For small areas (e.g. a single munipality) then you could use GDAL to build the tiles & simply serve them via a Web server. However this requires you to generate *all* tiles at once and doesn't support single-colour tiles (e.g. for Oceans which don't nee complexity and so can take advantage of server-optimisations).
