Abstract
Abstract A sequence of identical planar maps having intervals with contour lines drawn thereon are cut so that from each map a section defined by a pair of spaced contour lines of selected intervals are formed. The cut sections are then superimposed one upon the other in the order of the contour lines until the relief map is formed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
181 words
A method of forming a three dimensional relief map comprising the steps of employing a predetermined number of identical planar maps having intervals of contour lines drawn thereon, cutting each map in sequence to provide from each of said maps a section defined along one edge by a first contour line and along a second edge by a second contour line spaced at a selected interval therefrom, with at least one contour line intermediate and less than the total extent of said map, the one edge of each section cut from each succeeding map in said sequence being defined by the next adjacent succeeding contour line in order from that of the one edge of the section cut from the preceding map until at least one section from each map is cut, and thereafter cyclically repeating the cutting of said maps in successive order until a selected number of successive sections are obtained, and thereafter superimposing said sections one on the other in order of the next adjacent succeeding contour line one upon the other until said relief map is completed.
Claim 2
Independent Claim
181 words
A method of forming a three dimensional relief map comprising the steps of employing a predetermined number of identical planar maps having intervals of contour lines drawn thereon, cutting each map in sequence to provide from each of said maps a section defined along one edge by a first contour line and along a second edge by a second contour line spaced at a selected interval therefrom, with at least one contour line intermediate and less than the total extent of said map, the one edge of each section cut from each succeeding map in said sequence being defined by the next adjacent succeeding contour line in order from that of the one edge of the section cut from the preceding map until at least one section from each map is cut, and thereafter cyclically repeating the cutting of said maps in successive order until a selected number of successive sections are obtained, and thereafter superimposing said sections one on the other in order of the next adjacent succeeding contour line one upon the other until said relief map is completed.
Claim 3
Dependent Claim
22 words
The method according to claim 1, including the step of securely mounting each map on a substantially rigid planar base before cutting.
Claim 4
Dependent Claim
20 words
The method according to claim 2, wherein said base is selected from the group consisting of expanded plexiglass and acrylic.
Claim 5
Dependent Claim
28 words
The method according to claim 1, wherein the interval between the pair of spaced contour lines defining each section is equal to the number of the maps employed.
