But if you want to check true LOS, then no program is going to know about the trees.
Only way to do that is to either gamble and try it, or get up there somehow.
Get the lift trucks, or get some nimble tree climbers (with good insurance) to climb the tallest trees and see if they can see each other.
Mirrors reflecting sunlight work excellently for this. Use a program to narrow down the azimuth you need.
Or perhaps you might consider what the defunct wireless cable people had to do here in Georgia. We have tall pine trees and rolling terrain that causes everything to be blocked from almost everything else (or so it seems). They simply got the tree climbers to put the subscriber antennas right in the tops of the Pines. They used patch antennas about 1 ft square on telescoping masts that were somehow mounted to the tree trunk. I guess with some type of straps.
It was too bad we couldn't use these now-abandoned antennas for our Freenet here, but they have internal down-converters to TV channels and are fed with RG6 cable.

End Of Quoted TextSo, is there any alternatives that anyone knows about, such as maybe hiring a survey company to check this out for a small fee, or will I have to manually trace the line of sight and measure each tree and building with a protractor, line weight and tape measure. Or maybe rent a couple of 50' boom lifts and verify it that way. Any ideas ?? eless
