Label | Explanation | Data Type |

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 | The surface elevation property that will be added to the attribute table of the input feature class. The following list summarizes the available property keywords and their supported geometry types: - Z —Surface Z values interpolated for the XY location of each single-point feature.
- Minimum Z —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.
- Maximum Z —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.
- Mean Z —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.
- Surface Area —3D surface area for the region defined by each polygon.
- Surface Length —3D distance of the line along the surface.
- Minimum Slope —Slope value closest to zero along the line or within the area defined by the polygon.
- Maximum Slope —Highest slope value along the line or within the area defined by the polygon.
- Average Slope —Average slope value along the line or within the area defined by the polygon.

Method (Optional) | Interpolation method used in determining information about the surface. The available options depend on the data type of the input surface: - Bilinear —An interpolation method exclusive to the raster surface which determines cell values from the four nearest cells. This is the only option available for a raster surface.
- Linear — Default interpolation method for TIN, terrain, and LAS dataset. Obtains elevation from the plane defined by the triangle that contains the XY location of a query point.
- Natural Neighbors — Obtains elevation by applying area-based weights to the natural neighbors of a query point.
- Conflate Minimum Z — Obtains elevation from the smallest Z value found among the natural neighbors of a query point.
- Conflate Maximum Z — Obtains elevation from the largest Z value found among the natural neighbors of a query point.
- Conflate Nearest Z — Obtains elevation from the nearest value among the natural neighbors of a query point.
- Conflate Z Closest To Mean — Obtains elevation 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) | Excludes portions of the surface that are potentially characterized by anomalous measurements from contributing to slope calculations. Line features offer a length filter, whereas polygons provide an area filter. The value corresponding with either filtering option is evaluated in the linear units of the feature's coordinate system. Non-slope properties are not affected by this parameter. | String |
