The invention comprises an information carrier on which the position of a measuring
point (37, 41) may be determined using a mobile readout device, as well
as an attendant method of determining a position wherein the information carrier
features a surface onto which a visible primary information has been applied, in
the manner of a book or a geographic map, wherein at least one machine-readable
pattern has been printed on the surface, said pattern coding a position information,
which upon bringing to bear methods of image analysis and of local sampling of
parts (36, 40) of the surface, will allow a determination of position for
a measurement point (37, 41) and wherein the pattern coding the position
information is transparent in such a way that the primary information on the surface
remains visible.
