Input Ports
This transformer accepts only point cloud features.
Output Ports
Point or multipoint features based on the selected Output Geometry.
Parameters
-
Spatial Equal Points Multipoints: The input point cloud will be coerced into one or more multipoint geometries, each of which contains at most Maximum Points Per Multipoint. This mode guarantees that output multipoints will be spatially disjoint from each other, but performs slower than Sequential Equal Points Multipoints. This method attempts to split the point cloud into multipoints that have an equal number of points, as close as possible to the specified maximum size. Note that this option could result in memory errors if the input point cloud is very large.
- Sequential Equal Points Multipoints: The input point cloud will be coerced into one or more multipoint geometries, each of which contains at most Maximum Points Per Multipoint. This method splits up the point cloud by making a multipoint from the first N points, then another multipoint from the next N points, etc. Note that output multipoints may overlap each other.
-
Nested Equal Area Multipoints: The input point cloud will be coerced into one or more multipoint geometries, each of which contains at most Maximum Points Per Multipoint. This mode guarantees that output multipoints will be spatially disjoint from each other, but performs slower than Sequential Equal Points Multipoints. This mode attempts to split the point cloud into a set of tiles that have an equal area. If a tile contains too many points, it is further subdivided. This method performs faster than Spatial Equal Points Multipoint and is not restricted by point cloud size, but likely will produce a greater number of multipoints containing a lower average number of points.
- Single Multipoint: The input point cloud will be coerced into a single multipoint geometry. Note that this option could result in memory errors if the input point cloud is very large.
- Individual Points: The input point cloud will be coerced into individual points.
Specifies the maximum number of points in output multipoint geometries.
Specifies which point cloud components should be preserved, either as attributes on output features or measures on output point geometries.
Specifies whether point cloud components should be preserved as attributes or measures.
Specifies whether attributes of the input feature should be preserved on the output features.
An attribute to be added to each output feature, indicating its part number. For each input feature, the first output feature will be part 0, the second will be part 1, and so on.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
