Add Z Information

Add Z Information Tool, 3D Features Toolset, 3D Analyst Toolbox:

Adds information about elevation properties of features in a Z-enabled feature class.

Each 3D shape is examined and the selected properties are appended to the attribute table of the input feature class. The output options vary based on the feature's geometry.

1.    Input Feature Class:

The input features to process.

2.     Output Property:

The Z properties that will be added to the attribute table of the input feature class. The following options are available:

· Z—Spot elevation of single-point feature.

· POINT_COUNT—Number of points in each multipoint feature.

· Z_MIN—Lowest Z value found in each multipoint, polyline, polygon, or multipatch feature.

· Z_MAX—Highest Z value found in each multipoint, polyline, polygon, or multipatch feature.

· Z_MEAN—Average Z value found in each multipoint, polyline, polygon, or multipatch feature.

· LENGTH_3D—3-dimensional length of each polyline or polygon feature.

· SURFACE_AREA—Total area of the surface of a multipatch feature.

· VERTEX_COUNT—Total number of vertices in each polyline or polygon feature.

· MIN_SLOPE—Lowest slope value calculated for each polyline, polygon, or multipatch feature.

· MAX_SLOPE—Highest slope value calculated for each polyline, polygon, or multipatch feature.

· AVG_SLOPE—Average slope value calculated for each polyline, polygon, or multipatch feature.

· VOLUME—Volume of space enclosed by each multipatch feature.

3.     Noise Filtering (optional):

An optional numeric value used to exclude portions of features from the resulting calculations. This can be useful when the 3D input contains relatively small features with extreme slopes which may bias statistical results. If the 3D input's linear units are meters, specifying a value of 0.001 will result in the exclusion of lines or polygon edges that are shorter than 0.001 meters. For multipatch features, the same value will result in the exclusion of its subparts that have an area less than 0.001 square meters. This parameter does not apply to point and multipoint features.

The Area filter is made available when the input is a multipatch, whereas the Length filter is provided when the input is a line or polygon.
