Regularize Building Footprint

Regularize Building Footprint, 3D Features Toolset, 3D Analyst Toolbox:

 

Regularize Building Footprint

Normalizes the footprint of building polygons by eliminating undesirable artifacts in their geometry.

1.    Input Features

The polygons that represent the building footprints to be regularized.

2.    Method

The regularization method to be used in processing the input features.

· RIGHT_ANGLES—Useful for building footprints that are primarily defined by right angles

· RIGHT_ANGLES_AND_DIAGONALS—Useful for buildings footprints that are comprised of right angles and diagonal sides

· ANY_ANGLE—Useful for buildings with highly irregular footprints

· CIRCLE—Useful for buildings with circular characteristics, like grain silos and water towers

3.    Tolerance

The maximum distance that the regularized footprint can deviate from the boundary of its originating feature. The specified value will be based on the linear units of the input feature's coordinate system.

4.    Densification (optional)

The sampling interval that will be used to evaluate whether the regularized feature will be straight or bent. The densification must be equal to or less than the tolerance value.

This parameter is only used with methods that support right angle identification.

5.    Precision (optional)

The precision used by the spatial grid employed in the regularization process. Valid values range from 0.05 to 0.25.

6.    Diagonal Penalty (optional)

Controls the distance bias for creating right-angle connections. Distances smaller than the diagonal penalty will be used to create right angles.

This parameter is only used with the Right Angles and Diagonals method.

7.    Minimum Radius (optional)

The smallest radius that a regularized circle can have. A value of 0 implies there is no minimum size limit. This option is only available with the Circle method.

8.    Maximum Radius (optional)

The largest radius that a regularized circular can have. This option is only available with the Circle method.

9.    Output Feature Class

The feature class that will be produced by this tool.

 Union 3D

Union 3D

Union 3D Tool, 3D Features Toolset, 3D Analyst Toolbox:

 

Union 3D

Merges closed, overlapping multipatch features from an input feature class.

1.    Input Multipatch Features

The multipatch features that will be unioned.

2.    Grouping Field (optional)

The field used to identify the features that should be grouped together.

3.    Output Feature Class

The output multipatch feature class that will store the aggregated features.

4.    Output Table (optional)

A many-to-one table that identifies the input features that contribute to each output.

5.    Disable Optimization (optional)

Specifies whether optimization is performed or not performed on the input data. Optimization will preprocess the input data by grouping them to improve performance and create unique outputs for each set of overlapping features.

· Unchecked—Optimization is enabled, and the grouping field is ignored. This is the default.

· Checked—No optimization is performed on the input data. Features will either be stored in a single output feature or be unioned according to their grouping field, if one is provided.

6.    Output All Solids (optional)

Determines if the output feature class contains all features or only the overlapping ones that were unioned.

· Checked—All input features are written to the output. This is the default.

· Unchecked—Only unioned features are written to the output. Non-overlapping features will be ignored.

Update Feature Z

How to use Update Feature Z Tool in Arc Toolbox ArcMap ArcGIS ??

 

Update Feature Z

Update Feature Z Tool, 3D Features Toolset, 3D Analyst Toolbox:

 

Update Feature Z

Updates the z-coordinates of 3D feature vertices using a surface.

1.    Input Features

The 3D features whose vertex z-values will be modified.

2.    Input Surface

The surface that will be used to determine the new z-value for the 3D feature vertices.

3.    Interpolation 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 a 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_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.

4.    Status Field (optional)

An existing numeric field that will be populated with values to reflect whether the feature's vertices were successfully updated. A value of 1 would be specified for updated features and 0 for features that were not updated. Features that partially overlap the surface will not be updated.
