I'm sorry, next text is copied from the thBook: ‘survey’ …. • entrance <station-name> ▷ specifies the main entrance to the cave represented by this survey. If not specified and there is exactly one station marked entrance in this survey, it is considered to represent a cave also. This information is used for cave-list export. ‘centreline’ Description: Survey data (centreline) specification. The syntax is borrowed from Survex with minor modifications; the Survex manual may be useful as an additional reference for the user. A synonym term ‘centerline’ may be used. Syntax: centreline [OPTIONS] date <date> team <person> [<role So if it is right, what you wrote, Pavel, there is the serious bug. m.

Then "export cave-list -location on -o cave.html" gives you coordinates and lenght and depth of your surveys compiled, conected with defined entrances. If you have a index.th, which connects all your caves (every cave has to be at least in one or more surveys; and more surveys connected under one general cave survey), then you have list of all caves with one or more defined entrances.

However, this gives an error unknown command -- entrance Now I can sort of get round it using Station 0 "" entrance in the centerline, but this does not define a cave so the list is a bit weird. Am I missing something?
