Abstract

A digitising system has a digitising table (3), a computer (4), in which the finished data can be stored, an image processor (2) and a cursor (1) which is both positionally and orientationally locatable when disposed on the digitising table (by means of a pair of coils (12A, 12B)). The cursor also has a scanning device (11) for scanning an object chart or the like held against the digitising table, whereby predetermined coloured lines drawn on the chart and scanned by the scanner can be located and positional data relating thereto stored in the computer for further analysis.
