Interpolate Shape
Creates 3D features by
interpolating z-values from a surface.
1. Input Surface
The surface to use for interpolating z-values.
2. Input Feature Class
The input features to process.
3. Output Feature Class
The feature class that will be produced by this tool.
4. Sampling Distance (optional)
The spacing at which z-values will be interpolated. By default, this is a raster dataset's cell size or a triangulated surface's natural densification.
5. Z Factor (optional)
The factor by which z-values will be multiplied. This is typically used to convert Z linear units to match XY linear units. The default is 1, which leaves elevation values unchanged. This parameter is disabled if the spatial reference of the input surface has a Z datum with a specified linear unit.
6. Method (optional)
Interpolation method
used to determine elevation values for the output features. The available
options depend on the surface type being used.
·
BILINEAR—Determines the value of the query point using bilinear
interpolation. This is the default when the input is a raster surface.
·
NEAREST—Determines the value of the query point using nearest
neighbor interpolation. When this method is used, surface values will only be
interpolated for the input feature's vertices. This option is only available
for a raster surface.
·
LINEAR— Default interpolation method for TIN, terrain, and LAS
dataset. It 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_ZMIN— Obtains elevation from the smallest z-value found
among the natural neighbors of a query point.
·
CONFLATE_ZMAX— Obtains elevation from the largest z-value found
among the natural neighbors of a query point.
·
CONFLATE_NEAREST— Obtains elevation from the nearest value among
the natural neighbors of a query point.
·
CONFLATE_CLOSEST_TO_MEAN — Obtains elevation from the z-value that
is closest to the average of all the natural neighbors of a query point.
7. Interpolate Vertices Only (optional)
Specifies whether the
interpolation will only occur along the vertices of an input feature, thereby
ignoring the sample distance option. When the input surface is a raster and
nearest neighbor interpolation method is selected, the z-values can only be
interpolated at the feature vertices.
·
Checked—Interpolates along the vertices.
·
Unchecked—Interpolates using the sampling distance. This is the
default.
8. Pyramid Level Resolution (optional)
The z-tolerance or window-size resolution of the terrain pyramid level that will be used by this tool. The default is 0, or full resolution.
9. Preserve features partially outside surface (optional)
Specifies whether
features with one or more vertices that fall outside the raster's data area
will be retained in the output. This parameter is only available when the input
surface is a raster and the nearest neighbor interpolation method is used.
·
Checked—Each vertex that falls outside the raster surface will
have its z-value derived from the trend of z-values calculated for the vertices
within the raster surface.
· Unchecked—Features with at least one vertex that falls outside the raster surface will be skipped in the output. This is the default.

Intersect 3D Line With Surface
Computes the geometric
intersection of 3D line features and one or more surfaces to return the
intersection as segmented line features and points.
1. Input Line Features
The input 3D line features.
2. Input Surfaces
One or more surfaces that will be used to determine the points of intersection.
3. Output Lines
The output line features that represent the input line features split at the points of intersection with the surface.
4. Output Points (optional)
The optional point features that represent the input line's intersection with a surface.
