     1= Radio Coverage =
     2[[TOC]]
     3We want to display Radio coverage for:
     4* FM Transmitters (to show service delivery for Beneficiary Communications)
     5* VHF Repeaters (to show where staff can have security telecomms)
     6* GSM Mobile reception - inc separate ones for 2G/3G
     7
     8== Off-system ==
     9Can use [http://www.cplus.org/rmw/english1.html Radio Mobile] to do this off-system & then simply display the results on the Map.
     10
     11Radio Mobile can export KML:
     12* http://radiomobile.pe1mew.nl/?How_to:Work_with_Google_Earth:Import_coverage...
     13
     14To use this as-is we'd need to merge this patch to !OpenLayers:
     15* https://github.com/openlayers/openlayers/pull/759
     16
     17Alternatively we could convert the PNG to geoTIFF & serve as WMS from !GeoServer:
     18{{{
     19gdal_translate -of Gtiff -a_ullr LEFT_LON UPPER_LAT RIGHT_LON LOWER_LAT -a_srs EPSG_PROJ INPUT_PNG_FILE OUTPUT_GTIFF_FILE
     20}}}
     21
     22Alternatively we could Vectorise & import the Polygon(s) directly into Sahana:
     23* ''tbc''
     24
     25== In-system ==
     26Ideally we'd like to be able to
     27
     28Radio Mobile uses the Longley-Rice Irregular Terrain Model:
     29* http://www.cplus.org/rmw/data.html
     30* http://en.wikipedia.org/wiki/Longley%E2%80%93Rice_model
     31
     32The most promising thing to base off is this as it uses OGR which has Python bindings:
     33* https://github.com/QDeltaSoft/qradiopredict
     34
     35Even 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...
