I did similar thing in one map transferred to Therion from Illustrator. See attached image. The principle is I made an underlaying dummy scrap filled with area with pink colour bounded by wall type invisible. The profile is filled by colour by color map-fg command. So in final map the pink area is overlaid by map of cave. But it was made by hand drawing not generated as special kind of line wall. Martin

thanks for the answers
I don't know what Metapost or CSS box-shadow are (yet...)
I'll do a bit of reading about it and try to make it work

It may be possible to do this with CSS and SVG too. Export your cave survey as SVG, and use CSS box-shadow to add an outline.
You may do it directly in Metapost.
