ABSTRACT:

TECHNICAL FIELD
The invention relates to a method of recording into a storage, in particular of a navigation and positioning or a locating system, of geographic data of geographic places such as the points or spots of an itinerary or route in a predetermined geographic zone and an arrangement for bringing this method into operation.
BACKGROUND ART
The navigation and positioning or locating systems owing to their digital bases of geographic data of a given geographic zone are conceived or designed for guiding their users along a pre-established itinerary or route and for checking the accuracy of their positions during a displacement or travel.
One already knows methods and arrangements of the type defined hereinabove which allow a user to add his own personal data such as a fishing pots or zones for a seaman or sailor, restaurants interesting for a motorist, monuments along a pre-established itinerary or route, mushrooms or flowers zones for a tripper, walker or excursionist.
The known method and arrangements are based upon the use of a digitalizing table or of an electronic map recorded in an appliance or device on which the user would electronically plot the points or spots he wishes to define.
Now these known methods and arrangements exhibit the major inconvenience that a digitalizing table or an electronic map to be used is cumbersome or bulky and heavy and therefore usable with difficulty for many leisure or spare time utilizations where it is mandatory to have the lightest possible equipment available and for professional utilizations requiring a minimum bulkiness or size.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a method and an arrangement of the kind defined hereinabove which would cope with the inconveniences of the state of prior art.
To reach that goal, the method according to the invention includes the steps of selecting two points on a geographic map of the geographic zone in which points corresponding to geographic places or spots should be indicated, defining these points by their geographic co-ordinates such as their longitude and their latitude and by their co-ordinates of position on the map, establishing the correlation between the geographic and position co-ordinates, defining the points to be recorded by their position co-ordinates, calculating from these position co-ordinates the geographic co-ordinates from or according to the correlation and entering the calculated geographic co-ordinates into the said storage.
The arrangement for bringing the process into operation is characterized in that it comprises a device for establishing a system of polar co-ordinates on a geographic map and for establishing the polar co-ordinates of the points lying on the map in this system, a recording device for the recording by the user of geographic co-ordinates and for receiving polar coordinates and calculation means adapted for calculating, for polar co-ordinates, the geographic co-ordinates.
