[Therion] Finding undated surveys

[Bruce]

Andrew
Despite the message wording, I am pretty sure 'date' is a centreline
property, rather than an 'survey' property.  The surveys just inherit the
range of dates from their centrelines.
>From memory, which is often faulty, any centreline with survey shots ('data'
statements) will trip this warning if there is a cs defined (globally) but
there is no date in that centreline.

One that caught me out once was adding 
data  nosurvey etc
in a centreline of it's own - I had to add a date that the shot was not
surveyed!  (Also that nosurvey shots actually add their lengths to the
surveyed length) 

So to answer your question, I cannot think of an easy way, unless creating a
sql output and then querying that will work for you.

Not sure if Dave Clucas' project http://sarawak-caves.com/php/websearch.php
could be made to seek out undated surveys as it stands?
The 'Lengths' query has a field for dates, but I don't think 'undated' will
work.  I guess if the output had 'approx', 'date' and 'explo-date' columns,
you could scan down the table for blanks.

Hello

I am getting the message

warning -- unable to determine magnetic declination for undated surveys

Now I am reasonable sure that all the surveys are dated, as I use
topParser and it puts it in automatically. however I would like to
check, I cannot find a way of finding which surveys Therion finds to
be undated, Is there an easy/built in way, Maybe it would be good if
Therion listed them in the output log

thanks

Andrew
