Summary
Creates multipatch features that represent the volume of space occupied by a set of 3D features.
Usage
Consider using the Convex hull option (geometry_type = "CONVEX_HULL" in Python) to approximate the volume of space enclosed by data that can be modeled by a plume.
Consider using the Sphere or Envelope option (geometry_type = "SPHERE" or geometry_type = "ENVELOPE" in Python) to get a quick estimation of the volume of space occupied by a set of 3D features.
This Concave hull option (geometry_type = "CONCAVE_HULL" in Python) is computationally heavy and should not be used with large collections of input data.
Syntax
MinimumBoundingVolume_3d (in_features, {z_value}, out_feature_class, {geometry_type}, {group}, {group_field}, {mbv_fields})
Parameter | Explanation | Data Type |
in_features | The LAS dataset or 3D features whose minimum bounding volume will be evaluated. | LAS Dataset Layer, Feature Layer |
z_value (Optional) | The source of Z values for the input data. | Field |
out_feature_class | The feature class that will be produced by this tool. | Feature Class |
geometry_type (Optional) | The method used to determine the geometry of the minimum bounding volume.
| String |
group (Optional) | Specifies how the input features will be grouped; each group will be enclosed with one output multipatch.
| String |
group_field [group_field,...] (Optional) | The field or fields in the input features that will be used to group features, when LIST is specified as group_option. At least one group field is required for the LIST option. All features that have the same value in the specified field or fields will be treated as a group. | Field |
mbv_fields (Optional) | Determines whether to add the geometric attributes in the output multipatch feature class or to omit them.
| Boolean |
