what is the best way to generate cave passage rose diagrams from therion
data? Many thanks for any hints. Wolfgang Hi Wolfgang With some effort rose diagrams (and other information) can be extracted from Therion sql exports. http://therion.speleo.sk/wiki/doku.php/outputs?s[]=rose#database_sql <http://therion.speleo.sk/wiki/doku.php/outputs?s%5b%5d=rose#database_sql> http://therion.speleo.sk/wiki/doku.php/contrib:databasequery Andrew Atkinson and Dave Clucas have done some work here. http://wotcc.org.uk/Cheddar/ http://sarawak-caves.com/php/websearch.php (use the direction tab for rose diagrams) http://mycaves.net/php/websearch.php use the direction tab for rose diagrams) Dave's code for the last two is here http://www.daveclucas.com/cms/index.php/downloads/category/15-therion Bruce
. rose diagrams . from Therion sql exports. have some teething problems however. One is that the Therion sql export does not distinguish sufficiently survey legs from splay shots. (well, either Therion or the code used to manipulate the sql file) Hence the rose diagram reflects a combination of survey legs and splay shots, hence giving a somewhat meaningless (circular) result, especially where electronic surveying with copious splay shots has been employed. It works well where LRUD is used without splay shots however. Bruce
