Thanks Martin, Dave I'll try to look at this in the next few days. I think my naming convention is the same as Daves, so with any luck...

You may combine one map from one cave with another map from second cave for particular export. This is very good idea I think. So all maps definitions are associated with the highest level of surveys. Martin 18. 7. 2014 v 7:15, Dave Clucas <dave@daveclucas.com>: Bruce, I've written a php program to list all surveys which don't have an associated map. It can be downloaded here <http://www.daveclucas.com/cms/index.php/downloads/category/15-therion> . This was written for my dataset so may not work for you. Essentially all my survey names take the form survey_name and the associated maps are named surveyNamePlan or surveyNameElev300 so I am able to match maps with surveys by searching for the combination of words in the name. Give it a try and let me know how you get on. If it's OK I'll add it to the Wiki.
