Let me know what you think.


The Google Earth seems to be stitched together from a bunch of
satellite photos that range from old to very old. In some places I
know of highways & neighborhoods that have been in place ~10 years
that don't show up.

OTOH I have followed waterways on Google Earth to get an idea of
terrain & contour & development around potential anchorages. Kind of
interesting, possibly helpful. A lot of remote areas you can't zoom in
enough to get much detail.

2) Check outhttp://www.earthnc.com/
3) Learn about layers. This way the cans only appear when zoomed in on.
You don't want to see all of the info when zoomed way out.


That's cool. Thanks for the tip Geoff.

Doug, are there any free BSB charts available for the Tenn-Tom
waterways?

You can download ENC files from the Corps of Engineers but apparently
I don't ahve the right software to make them work.

The IENC files for the Tenn-Tom are included in basic form with
EarthNC Online (the free EarthNC version at http://earthnc.com/about_online)
and in full version with EarthNC Plus the $50 chart package which
covers the entire US (http://earthnc.com/earthnc-plus). In general,
the Army Corps river charts aren't as detailed as the NOAA coastal
charts, but they do provide the necessary navaids and depth contours
to get the job done.
