CALC_VOLUMES

CALC_VOLUMES

The CALC_VOLUMES command allows you to calculate the volume for each area in the specified layer using the currently loaded terrain data.

The following parameters are supported by the command:

• FILENAME - filename of the layer containing the areas to be used in the calculations. This parameter can be listed more than once to specify multiple input files, like FILENAME="FILENAME_1" FILENAME="FILENAME_2".
• OUTPUT_FILENAME - specifies the path and file name of the output file for volume statistics. At least one of this and the ADD_VOLUME_ATTRS parameter is required. Using both is valid also.
• ADD_VOLUME_ATTRS - indicates whether or not to add the volume measurements to the area features as attributes. Use ADD_VOLUME_ATTRS=YES to add the volume data to the feature attribute list. At least one of this and the OUTPUT_FILENAME parameter is required. Using both is valid also.
• BASE_ELEVATION - specifies the base elevation in meters for volume calculations. This parameter is optional. The default is 0.
• BASE_ELEVATION_ABOVE_SEA_LEVEL- Use BASE_ELEVATION_ABOVE_SEA_LEVEL=YES (or don't specify any value) to indicate that the BASE_ELEVATION parameter represents units above sea level. Use BASE_ELEVATION_ABOVE_SEA_LEVEL=NO to indicate that the base elevation is relative to ground. The default is NO, base elevation is relative to ground.
• VOLUME_UNIT - specifies the unit to be used for the volume calculations. This parameter is optional, and the default is CUBIC_METERS. Valid values are:
  • ACRE_FEET
  • ACRE_INCHES
  • BARRELS
  • BARRELS_OIL
  • CUBIC_FEET
  • CUBIC_METERS
  • CUBIC_YARDS
  • GALLONS

SAMPLE

Here is a sample of calculating volumes in cubic feet, adding the results to the features as attributes.
