Googles map service can show sattelite pictures, and one can enter
lon+lat directly in the URL so I played around with the LORSTA list
from NAVCEN and a little script:
LORSTA 9940X:
http://maps.google.com/maps?ll=38.782531,-122.495549&spn=0.068407,0.093985&t=k&hl=en
LORSTA 9660Y:
http://maps.google.com/maps?ll=34.062825,-77.912836&spn=0.068407,0.093985&t=k&hl=en
LORSTA 9660M:
http://maps.google.com/maps?ll=42.714088,-76.825919&spn=0.068407,0.093985&t=k&hl=en
And the best one I found so far:
LORSTA 9660X:
http://maps.google.com/maps?ll=41.253346,-69.977371&spn=0.008551,0.011748&t=k&hl=en
What I did was to take the lon+lat from
http://www.navcen.uscg.gov/loran/LoranSelectChain.htm
and enter it into this little script:
#!/bin/sh
(
echo 42 42 50.716 76 49 33.308 9660M SENECA NY
echo 41 15 12.046 69 58 38.536 9660X NANTUCKET, MA
echo 39 51 07.658 87 29 11 586 9660Z DANA, IN
echo 46 48 27.305 67 55 37 159 9660W CARIBOU, ME
echo 34 03 46.170 77 54 46.210 9660Y CAROLINA BEACH, NC
echo 57 26 20.300 152 22 10.650 9990Z KODIAK, NARROW CAPE, AK
echo 38 46 57.110 122 29 43.976 9940X MIDDLETOWN, CA
) |
awk '
{
printf "\n%s\n", $0
printf "http://maps.google.com/maps?ll="
printf "%.9f,", $1 + $2 / 60.0 + $3 / 3600.0
printf "-%.9f", $4 + $5 / 60.0 + $6 / 3600.0
printf "&t=k&hl=en\n"
}
'
Then paste the URLS to your browser and zoom in as far as google has
Satellite pictures.
Enjoy!
