Question marks handlingPossible continuations are treated special way in therion in both centerline and map files. You may associate text description, explored length (behind this continuation) or any other atribute to it (like Code if you have your own coding standard for continuations). Question marks in centerlineIn the centerline object, you may add a special flags to the station, where continuation is possible. Just use following syntax station 5 "pit" continuation attr Code V explored 20m When you export map and use symbol-show point flag:continuation in your layout, station with continuation flag specified is marked by question mark (continuation symbol is shown above the station).
You may redefine continuation symbol to show also
continuation description (stored in code metapost def p_continuation(expr pos,theta,sc,al) = % draw default continuation symbol p_continuation_UIS(pos,theta,sc,al); % if text attribute is set if known(ATTR__text) and picture(ATTR__text): % set labeling color to light orange push_label_fill_color(1.0, 0.9, 0.8); % draw filled label with text next to ? p_label.urt(ATTR__text,(.5u,-.25u) transformed T,0.0,8); % restore original labeling color pop_label_fill_color; fi; enddef; endcode Then also continuation description is displayed in the map. Question marks in maps
In the scrap (.th2 file), you can use point 796.0 676.0 continuation -attr Code A -explored 50m \ -text "water too cold to continue survey" In the map, also the question marks only are displayed by default. When you redefine continuation symbol as mentioned above, you can show also continuation codes and descriptions. Exporting question mark listsYou may also export a list of all continuations from your project project using export continuation-list -o questions.html File questions.html then contains following list:
