[[TOC]]
We want to display Radio coverage for:
* FM Transmitters (to show service delivery for Beneficiary Communications)
* VHF Repeaters (to show where staff can have security telecomms)
* GSM Mobile reception - inc separate ones for 2G/3G

== Off-system ==
Can use [http://www.cplus.org/rmw/english1.html Radio Mobile] to do this off-system & then simply display the results on the Map.

Radio Mobile can export KML:

To use this as-is we'd need to merge this patch to !OpenLayers:
* https://github.com/openlayers/openlayers/pull/759

Alternatively we could convert the PNG to geoTIFF & serve as WMS from !GeoServer:
{{{
gdal_translate -of Gtiff -a_ullr LEFT_LON UPPER_LAT RIGHT_LON LOWER_LAT -a_srs EPSG_PROJ INPUT_PNG_FILE OUTPUT_GTIFF_FILE
}}}

Alternatively we could Vectorise & import the Polygon(s) directly into Sahana:
* ''tbc''

== In-system ==
Ideally we'd like to be able to 

Radio Mobile uses the Longley-Rice Irregular Terrain Model:
* http://www.cplus.org/rmw/data.html
* http://en.wikipedia.org/wiki/Longley%E2%80%93Rice_model

The most promising thing to base off is this as it uses OGR which has Python bindings:
* https://github.com/QDeltaSoft/qradiopredict

Even with the ability to ignore UI, still a lot of work to try & work out what's being done in C++ & then converting to Python...
