Input Features | The point, multipoint, polyline, or polygon features that define the locations for determining one or more surface properties. | Feature Layer |

Input Surface | The LAS dataset, mosaic, raster, terrain, or TIN surface used for interpolating z-values. | LAS Dataset Layer; Mosaic Layer; Raster Layer; Terrain Layer; TIN Layer |

Output Property | Specifies the surface elevation property that will be added to the attribute table of the input feature class. - Z—The surface z-values interpolated for the x,y-location of each single-point feature will be added.
- Minimum Z—The lowest surface z-values in the area defined by the polygon, along the length of a line, or among the interpolated values for points in a multipoint record will be added.
- Maximum Z—The highest surface elevation in the area defined by the polygon, along the length of a line, or among the interpolated values for points in a multipoint record will be added.
- Mean Z—The average surface elevation of the area defined by the polygon, along the length of a line, or among the interpolated values for points in a multipoint record will be added.
- Surface Area—The 3D surface area for the region defined by each polygon will be added.
- Surface Length—The 3D distance of the line along the surface will be added.
- Minimum Slope—The slope value closest to zero along the line or within the area defined by the polygon will be added.
- Maximum Slope—The highest slope value along the line or within the area defined by the polygon will be added.
- Average Slope—The average slope value along the line or within the area defined by the polygon will be added.

Method (Optional) | Specifies the interpolation method that will be used to determine information about the surface. - Bilinear—An interpolation method exclusive to the raster surface which determines cell values from the four nearest cells will be used. This is the only option available for a raster surface.
- Linear— Elevation will be obtained from the plane defined by the triangle that contains the x,y-location of a query point. This is the default interpolation method for TINs, terrains, and LAS datasets.
- Natural Neighbors—Elevation will be obtained by applying area-based weights to the natural neighbors of a query point.
- Conflate Minimum Z— Elevation will be obtained from the smallest z-value found among the natural neighbors of a query point.
- Conflate Maximum Z— Elevation will be obtained from the largest z-value found among the natural neighbors of a query point.
- Conflate Nearest Z— Elevation will be obtained from the nearest value among the natural neighbors of a query point.
- Conflate Z Closest To Mean— Elevation will be obtained from the z-value that is closest to the average of all the natural neighbors of a query point.
| String |

Sampling Distance (Optional) | The spacing at which z-values will be interpolated. By default, the raster cell size is used when the input surface is a raster, and the natural densification of the triangulated surface is used when the input is a terrain or TIN dataset. | Double |

Z Factor (Optional) | The factor by which z-values will be multiplied. This is typically used to convert z linear units to match x,y linear units. The default is 1, which leaves elevation values unchanged. This parameter is not available if the spatial reference of the input surface has a z datum with a specified linear unit. | Double |

Pyramid Level Resolution (Optional) | The z-tolerance or window-size resolution of the terrain pyramid level that will be used. The default is 0, or full resolution. | Double |

Noise Filtering
(Optional) | Specifies whether portions of the surface that are potentially characterized by anomalous measurements will be excluded from contributing to slope calculations. Other properties are not affected by this parameter. Line features offer a length filter, wherein line segments whose 3D lengths are shorter than the specified value are excluded from slope calculations. Polygon features offer an area filter, wherein polygons covering a surface area smaller than the specified value are excluded. | String |
