This is both a standalone and companion site to the Longley 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 point to point and broadcast Longley Rice calculations. For BEST results and accuracy of placement a 4K monitor should be used. (Most Accurate Resolution: 3840 x 2160 on Edge or Safari). Lower resolution will give inaccurate placement ( eg: a 620 x 480 will have a 1Km accuracy placement)

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 Longley Rice model for calculation of the broadcast characteristice
The values are entered in degree, minute, second + compass format or selected from an abbreviated list.
