Cut Fill

Feature Description

Describes volumetric and areal changes between two raster datasets (before cut fill and after cut fill raster datasets). "Fill" indicates material addition in surface areas, while "Cut" represents material removal. The calculation result is derived by subtracting the before cut fill data from the after cut fill data. For principles and methodology, refer to the Surface Cut Fill section in Surface Analysis Overview.

Important considerations for input/output raster datasets:

  1. Input raster datasets must share identical coordinate and projection systems to ensure positional accuracy. Mismatched coordinate systems may produce erroneous results.
  2. Theoretically, input datasets should have identical spatial extents. For datasets with different extents, calculations will only process overlapping areas.
  3. Null values in either input raster will propagate as null values in the output dataset.

Feature Entry

  • Spatial Analysis Tab -> Raster Analysis -> Surface Analysis -> Cut Fill；
  • Toolbox -> Raster Analysis Tools -> Surface Analysis -> Terrain Calculation -> Cut Fill.

Parameter Description

  • Configure Before Cut Fill Raster Dataset
    • Datasources: Lists all datasources in current workspace. Select the datasource containing the before cut fill dataset.
    • Dataset: Lists all raster datasets (GRID) in selected datasource. Automatically locates datasets selected in Workspace Manager.
  • Configure After Cut Fill Raster Dataset
    • Datasources: Lists all datasources. Select the datasource containing after cut fill dataset (default matches source datasource).
    • Dataset: Lists all raster datasets. Select the after cut fill dataset.
  • Configure Result Data
    • Datasources: Select output datasource (default matches source datasource).
    • Dataset: Specify result dataset name. The output is generated by subtracting source data from cut/fill data.
  • Click "OK" to execute

    Execution results display in output window, including:
    Fill Volume (cubic meters), Cut Volume (cubic meters), Fill Area (square meters), Cut Area (square meters), and Unchanged Area. Example:
