About 1987, Manitoba Hydro, the CANADIAN provincial power company, placed in service a 138 kV transmission line from CYGX (Gillam) to CYYQ (Churchill) in Manitoba, CANADA. The line starts about 700 miles north of CYWG (Winnipeg) and runs north for about 175 miles. I flew from CYYQ to CYGX and could see the transmission line as a flew the route. I wonder how they knew that a small line like that was placed inservice? I work for Manitoba Hydro and know the line as I was in CYYQ when the line was placed in service. CYYQ was previousley powered by diesels. Microsoft, you always amaze me.JimCYWG

I think they paid top-dollar for this data and things like large overhead power lines are kept pretty up-to-date in government data files. I am also certain that the data is probably fairly up-to-date in North America, Western Europe and parts of Asia. The data is probably non-existent in other parts of the world.J

Hi, PICs, real and virtual. Have you noticed that what appears in FS200#'s basic scenery,is what is shown on our VTA and VNC REAL maps ? I would guess that "they" use official, easy to find data,to do their scenery, like, in Canada, FSS, CFS, AIP, ...etc......and, maybe, the net. Blue skies.
