Radio Coverage

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 ​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:

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...
