A Radiospurs Tool Site

This is both a standalone and companion site to the Langley Rice propagation models on the radiospurs.red site. Standalone because we can get the co-ordinates of transmitter-receiver sites, with the option to do pt to pt and broadcast Langley Rice calculations.

Propagation

Based upon the OpenStreetMap, SRMTv4.1 data bases and other specific OSM sources (Ordinance Survey UK amongst others), the mapping can be used to situate transmitters using location and elevation data. Terrain elevation profile can be extracted. The resultant Lat-Long information can the be imported into the Langley Rice model for calculation of the broadcast characteristice
