    Re: ONC Charts online
    From: Gerard Mittelstaedt

     I downloaded many of the online charts available on the NIMA
    Actually I downloaded all I could get, and that's quite a few.
    They can be downloaded in batches, zipped.
    Then I followed their links to the 3 different organizations that
    had free software to read these charts.
    One version would run on a Windows operating system below Win NT
    and the other 2 demanded NT or above.
    I loaded and ran the older version at  home, and got a map of
    sorts to display, but it is not very satisfying.
    At work I have Win 2000 running and loaded one of the other
    programs, but when attempting to view the chart selected I also
    got a much less than satisfactory result.
     I get water in blue, land in tan, bouys displayed, and where
    there are bridges and one brings one's mouse pointer over them
    the vertical clearance.  I do not see any depth of water.
    What am I doing wrong?
    I asked a friend who works on aeronautical charts for the Army
    (actually air navigation systems) and he never heard of the
    file format.
    Oh yes, when loading the chart file into the software one has
    to select file type... that took some hunting around.
    Any hints?

    I'm not sure if the
    application program can be downloaded (I've emailed to ask, but
    the email query form generates an error message so I have no idea
    if the query posted) and then the CD's must be purchase

    them. I'm going to see if NIMA replies. (Excuse me, NGA, they're
    not NIMA any more. Or maybe
    they still are NIMA until 1/1/2004...I just hope those guys don't
    have to buy new shoulder
    patches every time their name changes.)
