A Voronoi diagram is a special kind of decomposition of a space
determined by distances to a specified discrete set of objects in
the space, or by a discrete set of points or drillholes. It is
useful here to divide the mine area up into polygon linework for the area of influence around
drillholes. These are individual polyline segments, not closed
polylines.
The first dialog prompts whether
to use drillholes or simple CAD points for the input.
The next dialog prompts for the
layer name for the diagram linework to create. The Process Method
chooses between using all the drillholes at data points for the
diagram or using only drillholes that have a certain strata and
attribute.
When using Strata/Attribute, the next dialog asks for a strata
to analyze.
The next dialog prompts for the
value to process.
Select drillholes, channel samples
and strata polylines.
