c. Local Frame Parameters Select the distance Units (feet or meters). Enter the

bearing of the first survey line in the Line 1 Azimuth field. The software will use

this value to correctly orient images on maps that are exported as KMZ or HTML

files.

9. Enter the calibration dialog by pressing the Calibrate button. If there is an existing

calibration will be used to determine density/compaction, select that calibration now by

pressing the Open button and selecting the appropriate named calibration. Alternatively,

if cores from the first part of the survey will be used to make a new calibration, press the

New button and enter a name for the new calibration. Select the Density units: (i.e.,

Percent voids, Density (g/cc), Density (pcf), or Percent compaction). Finally, enter the

Minimum target density and Maximum target density. These values will be used when

generating reports to indicate the percentage of locations that fall within acceptable

limits.
