Abstract
Abstract A map of golf course hole layout produced as reproduction of one or plurality of aerial photographs by camera positioned at uniform distance from terrain along course showing each fairway and playing area between tee and green, said reproduction being substantially free from distortion throughout playing area with natural and artificial landmarks shown. Distance scale established by actual measurement along course represented by annotated indicia applied between two selected visible points used in measurement. Other indicia are applied to reproduction in arcuate pattern across playing area using indicated point on green as a center and in established scale distance units.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
208 words
The method of producing a map of the layout of a golf course which comprises photographing the playing portion of a golf course including the tee, fairway, rough and green associated with at least one selected hole of play of said golf course from a predetermined uniform elevation above the course with an essentially vertical camera position so as to obtain a photographic print substantially free from distortion and with all existing natural and artificial landmarks along the portion of said golf course photographed, making a reproduction of said print, determining the distance between two selected points along the portion of said golf course photographed by measurement in true scale, establishing a unit of distance in scale related to said reproduction from said first measurement, applying a first indicia of the distance between the two selected points on the reproduction in correct scale relation, applying other indicia to the reproduction in arcuate pattern using a visible point on the green representation as a center and with said arcuate pattern extending substantially across the width of the playing area inclusive of the fairway and rough so as to relate to adjoining landmarks, and applying distance annotations to at least a portion of said other indicia in actual scale relation.
Claim 2
Independent Claim
208 words
The method of producing a map of the layout of a golf course which comprises photographing the playing portion of a golf course including the tee, fairway, rough and green associated with at least one selected hole of play of said golf course from a predetermined uniform elevation above the course with an essentially vertical camera position so as to obtain a photographic print substantially free from distortion and with all existing natural and artificial landmarks along the portion of said golf course photographed, making a reproduction of said print, determining the distance between two selected points along the portion of said golf course photographed by measurement in true scale, establishing a unit of distance in scale related to said reproduction from said first measurement, applying a first indicia of the distance between the two selected points on the reproduction in correct scale relation, applying other indicia to the reproduction in arcuate pattern using a visible point on the green representation as a center and with said arcuate pattern extending substantially across the width of the playing area inclusive of the fairway and rough so as to relate to adjoining landmarks, and applying distance annotations to at least a portion of said other indicia in actual scale relation.
Claim 3
Dependent Claim
40 words
A method as defined in claim 1, in which one of the selected points is an indicated point on the tee of the portion of said golf course photographed and is used as a focus for applying the first indicia.
Claim 4
Dependent Claim
24 words
A method as defined in claim 1, in which the reprOduction is in color differentiation between vegetation, trees, water areas, sand traps and paths.
Claim 5
Dependent Claim
23 words
A method as defined in claim 1, in which all arcuate indicia of the reproduction are annotated in distances of said scale unit.
Claim 6
Dependent Claim
47 words
A method as defined in claim 1, in which two series of arcuate indicia are applied to the reproduction between tee and green, one having an indicated point on the tee as a focus and the other having an indicated point on the green as the focus.
Claim 7
Dependent Claim
34 words
A method as defined in claim 1, in which the determination of the scale unit of the reproduction is based on ground level measurement of the distance between two points visible in the reproduction.
