The point reference layer must be loaded into ArcMap before starting this tool (see below). This layer represents the center of the plot shape to be created.
The output of this tool is a polygon shapefile."
Select any of the listed plot shapes from the drop-down box.
The dimension of the plot polygon that is to be created can either be a constant value (one that you type in to the form when you run the
tool), or variable across points (in which case you must create a numerical attribute field in the point attribute table representing the dimension
before running this tool). In either case, the value of the dimension you supply has slightly different meanings for each of the sample shapes:
- SQUARES: the dimension is the distance from the center of the square to the southern boundary of the square (due south)
- CIRCLE: the dimension is the radius of the circle (note that you may wish to use the Buffer Features tool to obtain circles - it was included
here only for completeness)
- DIAMOND: the dimension is the distance from the center of the diamond to the southern point of the diamond (due south)
- HEXAGON: the dimension is the distance from the center of the hexagon to the southern boundary of the hexagon (due south)
-TRIANGLE: the dimension is the distance from the center of the triangle to the southern boundary of the square (due south). Note that currently the
triangles are all creates with a southern edge that runs East-West.
Note that this tool is designed to be used in conjunction with the Generate Regular Points tool to create complete vector grids of some of these sampling
shapes (e.g. hexagons).
