This is a discussion thread for the following file:<br><br><b><a href=http://www.gearthhacks.com/dlfile25210/Elbe-Crossing-2.htm>Elbe Crossing 2</a></b><br><br>Elbe Crossing 2 is a group of pylons providing overhead lines for four 380kV three phase AC current circuits across the River Elbe. It was constructed between 1976 and 1978 to supplement Elbe Crossing 1, and consists of 4 masts: <br />
<br />
* A 76 meter tall anchor pylon located in Lower Saxony, on the Elbe's southern banks. <br />
<br />
* Two carrying pylons, each 227 meters tall. One is located on the island of Lühesand and the other is near Hetlingen in Schleswig-Holstein, on the northern shore. <br />
<br />
These pylons are the tallest pylons in Europe and the sixth tallest of the world. They stand on 95 stakes because of the unfavorable building ground. They take a surface of 45 * 45 meters and weigh 980 tons. At heights of 172, 190 and 208 meters, they carry crossbeams so conductor cables can be attached. The spans of these crossbeams are 56 meters (lowest crossbeam), 72 meters (middle crossbeam) and 57 meters (highest crossbeam). Each pylon has a self-propelled climbing elevator for maintenance of the aircraft warning lights; each elevator runs inside a steel tube in the center of the mast, around which there is a spiral staircase. <br><br><img src=http://www.gearthhacks.com/images/new/080505/706110elbe.jpg>

these two towers (NE & SW) on the banks of the Elbe, offer a great example of the angle at which the satellite photograph was taken.
note that the shot of the SW tower (referred to in the title and on the NW side of the island) it taken from almost directly above. This is shown by the way the arms @ the top of the tower are almost centered over the base of the tower.
whereas, the NE tower (on the East side of the Elbe) shows the arms at the top of the tower off the base of the tower (towards the NE).

if you carfully follow the lines towards the SW and look @ the shorter towers in the fields, you will note that their arms (at the top of the towers) are also off the base & towards the SW.

geeky, i suppose, but it was the 1st time i've noticed this aspect difference.
