ទិដ្ឋភាពទូទៅ

Optionally outputs the interpolated surface raster and a contour line feature class from the same run.

ការប្រើប្រាស់

  • Input Point Survey accepts point or polyline features. Points are survey spot levels; polylines are existing contour lines. Either can drive the surface.
  • Choose Z field must be a numeric field holding elevation. The tool reads the field's value range and pre-fills Minimum Elevation and Maximum Elevation from the data, so those two parameters normally need no editing. Override them to clamp the surface to a narrower range.
  • Specify Cut Fill elevation is the design level the surface is compared against. Cells above it are cut; cells below it are fill.
  • Specify Surface Cell Size controls the resolution of the interpolated surface. A small cell size over a large boundary produces a very large raster and a long run time. Match the cell size to the survey point spacing — interpolating far below the data density adds no real detail.
  • Input Boundary clips the interpolation to the project area. Without it, interpolation would extrapolate well beyond the surveyed extent.
  • Two optional outputs come from the same interpolation, so requesting them costs almost nothing extra:
    • Also generate Surface Raster? writes the interpolated elevation surface.
    • Generate Contour writes contour lines at the interval given in Specify Contour Interval.

Parameters for Cut Fill
ឈ្មោះប្រភេទទិន្នន័យការពិពណ៌នា
Input Point SurveyFeature Layer

The survey data used to build the surface. Point features (spot levels) or polyline features (contours).

Choose Z fieldField

The numeric field holding elevation values. Short, long, float, or double.

Minimum Elevationជម្រើសDouble

The lower bound of the surface. Pre-filled from the minimum value found in Choose Z field.

Maximum Elevationជម្រើសDouble

The upper bound of the surface. Pre-filled from the maximum value found in Choose Z field.

Specify Surface Cell SizeDouble

The cell size of the interpolated surface, in the input's coordinate system units.

Input BoundaryFeature Layer

The polygon that clips the interpolated surface to the project area. Polygon geometry only.

Specify Cut Fill elevationDouble

The design or target elevation that the surface is compared against.

Output Cut-Fill RasterRaster Dataset

The raster recording cut and fill volumes per cell.

Also generate Surface Raster?ជម្រើសBoolean

Writes the interpolated elevation surface as a separate raster.

  • Checked — Output Surface Raster is enabled.
  • Unchecked (default) — Only the cut-fill raster is written.
Output Surface Rasterជម្រើសRaster Dataset

The interpolated elevation surface. Required when Also generate Surface Raster? is checked.

Generate Contourជម្រើសBoolean

Writes contour lines derived from the interpolated surface.

  • Checked — Specify Contour Interval and Output Contour Line are enabled.
  • Unchecked (default) — No contours are written.
Specify Contour Intervalជម្រើសDouble

The vertical interval between contour lines. Required when Generate Contour is checked.

Output Contour Lineជម្រើសFeature Class

The contour line feature class. Required when Generate Contour is checked.

របៀបប្រើ

  1. Add the survey point or contour layer and the project boundary polygon to the map.
  2. On the KGA Toolbox tab, in the Spatial Analysis group, open the Spatial Analysis menu and click Cut Fill.
  3. Set Input Point Survey and Choose Z field. Check that Minimum Elevation and Maximum Elevation have been filled in from the data.
  4. Set Specify Surface Cell Size to suit the survey point spacing.
  5. Set Input Boundary to the project area polygon.
  6. Type the design level in Specify Cut Fill elevation.
  7. Set Output Cut-Fill Raster.
  8. To also keep the surface or contours, check Also generate Surface Raster? or Generate Contour and complete the enabled parameters.
  9. Click Run.
