Thanks Bruce for the code, I should have found that myself in the wiki,
sorry. It's exactly what I needed.

Yes.

You can add some tex code to a layout. See
_http://therion.speleo.sk/wiki/doku.php?id=tex#overriding_data_supplied_by_therion_map_headers_
(http://therion.speleo.sk/wiki/doku.php?id=tex#o
verriding_data_supplied_by_therion_map_headers)
Eg
code tex-map
\cavedepth{300\thinspace{}ft} %forcing reported depth to 300 ft
endcode
>I can see how this could be a significant issue if you had a cave with
little vertical extent except for a high dome. You would have to shoot a shot
to a station at the top of the dome to capture it's vertical extent in the
legend data.
That would avoid the need to manually edit the depth each time you
suspected a new survey might change the depth of the cave. It would be my
preferred method, even if it means creating an artificial shot to replicate the ‘up
’ data. It would need ‘flags duplicate’ to prevent it being added to the
reported survey network length.
