Point Values

 

 

Point Values

The Point Values table contains borehole data not easily tied to a elevation interval.  This for example would be useful for a set of continuous or near continuous measurements down the length of a hole that result in hundreds or more observations in a single hole.  Text string remarks on boring log samples may also be stored in the Text Values field of the Point Values table.  Point Values can be charted in Strip Logs or posted in the downhole portion of sheet-size boring log plots.  Point Values data may also be displayed in downhole charts on x-sections and in 3d.
