Introduction*

After a less than satisfactory experience trying to produce a plan of an irregular and dimly lit interior, (a miner’s dugout dwelling in Burra, South Australia), struggling with insecure base lines, tapes, plumb bobs, etc., I designed and produced the following for a measuring device that would do that, and related jobs quickly, simply and accurately. The device is closely related in principle to the plane table and alidade described, for example, in Hobbs (1983:55–60) and Hester et al. (1997:211–212), but adapts the principle to interiors and similarly enclosed spaces, rather than to wider topography.

*Note that an abstract was not included with this paper, and so the introductory paragraph has been included here instead of the abstract.
