First Claim
1. A system providing for the determination of geographic points on maps, charts and other representations of geographic areas, with the geographic areas defined by borders having extremities therealong, said system comprising:
- a rectangular grid formed or orthogonal first, second, third and fourth boundaries about a representations of a geographical area,said first, second, third and fourth boundaries each tangent to a corresponding point on an extremity of the border of the represented geographical area,said first, second, third and fourth boundaries having intersections further defining first, second, third and fourth corners of said rectangulars grid,said rectangular grid further including a zero ordinate at one of said corners and unit ordinates at each of said corners orthogonal to said zero ordinate with said boundaries between said zero ordinate and said unit ordinates providing orthogonal decimal boundary scales between the ranges of zero and one, with said decimal boundary scales thereby serving to divide the geographical area fractionally, wherebylocations of points on said geographical area representation are provided by means of said decimal boundary scales of said rectangular grid with each said decimal boundary scale providing a series of decimal fractional numbers representing perpendicular lines of location across the geographical area representation and the intersections of the perpendicular lines of location establishing said locations of said points and any one of said points is represented by an array of two decimal fractions; and
,wherein at least two geographical representations of dissimilar scale are provided with said system providing like ordinates for like points within each representation.

Abstract
A system for locating geographic points on maps, charts and, the like uses a rectangular grid with sides tangent to the corresponding geographical extremities of the area (city, county, state, nation, etc.) represented on the chart. Two decimal scales extend from the zero ordinate of the grid, with unit ordinates at their opposite ends. Thus, a location along either scale and therefore a line of position across the enclosed geographical area represented, may be defined by a decimal number between zero and one and the intersection of the lines of position representing a point on the represented area may be defined by a two decimal array. Tables of the decimal arrays for specific points may be provided, and the system is extendible to different maps and/or insets of dissimilar scale, so long as the, decimal scales are consistently used between each map. The system may be further extended to provide point location within three dimensional volumes by using a three decimal array. The advantages of the system are numerous, including ease of visualization and ease of reading maps and charts of all types in general; ease of teaching geography and related subjects; and wide spread applicability to other areas.
