Splat seems like it's a great tool for modelling what RF coverage I should have. It can create a nice circle around me, after I download topology data from USGS, namely SRTM-1.
But when the coverage map (created using
-L 17) gets created it looks kind of like the logo on the Splat home page, which means I can't tell what's where on the map anymore.
Is there data for London (UK) I can overlay to make it clearer? I think I'm looking for cartographic boundary data. So it's this? But how do I convert it to the format that Splat wants?
