I got called out to a longtime customer location yesterday, a huge pole building was going up right in the path. Funny thing, I look on Google Earth today and the new building still isn’t there.
Until recently there were whole windfarms missing from Google Earth because the imagery was 6-8 years old, some of it was black & white. Most of our area is May 2013 now. I’ve had people plant new trees that get to be 35-40 feet tall that won’t show up in clutter data or Google Earth. Trust but verify.

I haven't found anything that beats Radio Mobile with Google Earth to see if there's anything that *might* be in the way when it gets near 0.7 fresnel. Path it out in RM, export to GE. Use RM to find where the fresnel gets close, then use GE to see if there's trees or whatever there. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------------------------------------- From: "Ty Featherling via Af" <af@afmug.com> To: af@afmug.com Sent: Thursday, October 23, 2014 11:20:20 PM Subject: Re: [AFMUG] Easy way to determine LOS Why doesn't everyone know about heywhatsthat.com? Their Path Profiler tool is used everyday in our office and I use the Panorama tool for quick and easy viewsheds. Great stuff and free. -Ty On Oct 23, 2014 6:21 PM, "Glen Waldrop via Af" <af@afmug.com> wrote: I use Terrain Navigator Pro. It isn't perfect, but it is pretty good. The elevation data around here is close, but not perfect. Places where there aren't people aren't terribly accurate, but it uses USGS elevation data, has the option for a line of sight, options to change the elevation above ground level at each point. The newer versions account for curvature of the Earth, but I'm using an antiquated version on XP. ----- Original Message ----- From: Shayne Lebrun via Af To: af@afmug.com Sent: Thursday, October 23, 2014 3:21 PM Subject: Re: [AFMUG] Easy way to determine LOS Path profile software with clutter data, and bear in mind that ‘I can see it’ and ‘RF Line-Of-Sight’ are two very separate things.
