FCC contour maps / Radio-Locator

A

aaronread

Does Radio-Locator.com rely on the same US Census Tiger maps that the FCC FM Query relies on?

If so, we're all kinda hosed for the moment...according to the FCC's website, the US Census bureau discontinued the Tiger mapping service at the end of May. Old maps will remain, but any new or changed maps won't exist. The FCC says they are "exploring alternatives".

RECnet's maps still work...but even for contour maps they're pretty inaccurate. For WITH they show a rough circle when I know the contours are this weird pattern that almost looks directional but isn't; it's just the terrain.
 
IIRC, Radio-Locator takes terrain into account, to a degree, in plotting its FM projected coverage contours--and takes ground and water conductivity in a region into account in drawing its AM directional pattern coverage contours as well. You'll notice they don't quite conform to the theoretical contours on the FCC site's data base, but IMHO are a fairly decent approximation of real-world reach of most of the signals I'm familiar with.
 
Talking about the FCCC, on June 19, 1934, The US Congress established the Federal Communication Commission to regulate broadcasting. Seventy six years later, it's still out-of-control.
