Being a bit of a wireless geek, it is a great starter tool to understand how much coverage area a mountain top has. In the example shown in the right you can see the coverage area from the Twin Peaks communications site in San Francisco. The orange\/red overlay indicates area that this site can see. You can see the shadowing of some of the hills of San Francisco affecting the coverage area.<\/p>\n<p>At the top of the frame, shows a panorama of the skyline seen from that site. The list on the right shows what mountain tops can been seen and distance to them.<\/p>\n<p>HeyWhatsThat is a great starting point in checking out coverage area. I wouldn&#8217;t throw away your <a href=\"http:\/\/www.edx.com\/\">$50,000 coverage software<\/a> just yet as that will be a bit more accurate using better algorithms to calculate coverage such as <a href=\"http:\/\/en.wikipedia.org\/wiki\/Longley%E2%80%93Rice_model\">Longley Rice<\/a> and TIREM as well as their own tweaks.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Google Maps has opened up access to resources that would take considerable work and expense to access.
