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.
