Abstract
Abstract The invention relates to a map bearing a graphic representation of cartographical information, broken down into a large number of elementary areas with which are associated respectively a large number of indexes. According to the invention, each index includes a group of dots (10) placed on the map in the vicinity of the associated elementary area and forming a specific code for the said area, the indexes as a whole forming a location frame covering the said geographical representation and superimposed thereupon, each group of dots being readable by optical reading means cooperating with a data processing system comprising a data medium addressable by means of the said indexes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
Map bearing a graphic representation of cartographic information, said representation being divided into a large number of elementary areas, each of said areas having an index associated therewith, each index including a group of dots placed on the map in the vicinity of the associated elementary area and constituting a specific code for said area, the indexes as a whole forming a location frame covering said graphic representation and being superimposed thereupon, each group of dots being readable by optical reading means cooperating with a data processing system comprising a data medium addressable by means of said indexes and containing information specific to the associated areas.
Claim 2
Dependent Claim
106 words
Map bearing a graphic representation of cartographic information, said representation being divided into a large number of elementary areas, each of said areas having an index associated therewith, each index including a group of dots placed on the map in the vicinity of the associated elementary area and constituting a specific code for said area, the indexes as a whole forming a location frame covering said graphic representation and being superimposed thereupon, each group of dots being readable by optical reading means cooperating with a data processing system comprising a data medium addressable by means of said indexes and containing information specific to the associated areas.
Claim 3
Dependent Claim
67 words
Map according to claim 1, designed to be read by optical reading means including an ordered matrix of pixels, each group of dots forming each said index comprising an elementary matrix of pixels distributed in a substantially isotropic manner, the dots in said group of dots being distributed over certain of the pixels in said elementary matrix so as to permit binary coding of each of them.
Claim 4
Dependent Claim
33 words
Map according to claim 2, wherein only certain pixels in said elementary matrix have an encoding dot, said certain pixels being separated from one another by at least one pixel without encoding dot.
Claim 5
Dependent Claim
17 words
Map according to claim 3, wherein only a small number of the pixels has an encoding dot.
Claim 6
Dependent Claim
42 words
Map according to claim 1, wherein the dots in each group of dots are disposed in relation to one another so as to define a reference system which comprises two orthogonal directions and is unique for the whole of the location frame.
Claim 7
Dependent Claim
19 words
Map according to claim 2, wherein said elementary matrix is formed by several rows and several columns of pixels.
Claim 8
Dependent Claim
44 words
Map according to claim 6, wherein certain of said rows or columns of pixels define said index, each row or column having dots distributed so as to form a code of the "3 out of 5" type representing a figure from 0 to 9.
Claim 9
Dependent Claim
33 words
Map according to claim 1, wherein the different groups of dots in the location frame are disposed in relation to one another so as to define a reference system comprising two orthogonal directions.
Claim 10
Dependent Claim
19 words
Map according to claim 8, wherein the different groups of dots are arranged after the fashion of a checkerboard.
Claim 11
Dependent Claim
46 words
Geographical information system including a map according to claim 1, further comprising an optical wand reader having a scanning field covering several juxtaposed indexes, and an illumination means having a given wavelength, for enabling discrimination between said location frame and said graphic representation of cartographical information.
Claim 12
Dependent Claim
31 words
Geographical information system according to claim 10, further comprising a data processing system including a data medium addressable by means of said indexes and containing information specific to the associated areas.
