PointCloudCombiner is often used to accumulate multiple point clouds into a single point cloud feature, but can also convert other geometries into point clouds and merge them.
点和线性功能将被转换为点的点。多边形，甜甜圈，表面和固体特征将被转换成位于由该区域计算的3D面积的区域内的区域内的点网格。存储为度量或属性的任何现有组件值都可以保留为组件。
栅格将转换为点云，如下所示：
- The x and y components will be created from the columns and rows.
- The first selected numeric band will become the z component.
- 具有红色/绿色/蓝色/灰色解释的第一个选定的乐队将成为Color_Red / Color_Green / Color_Blue组件。
- 还将保留其他选择的频带。如果频段有名称，则组件名称将是频带名称。如果频段没有名称，则组件名称将是带数，其中n是频带索引。
Input Ports
Input
该变压器接受所有几何形状。基于区域的几何形状将根据间距参数转换为点云。
输出端口
输出
A single point cloud feature.
参数
变压器
Group By
Use this parameter to organize point clouds into groups. Each group of point clouds will have its own output point cloud.
Parallel Processing Level
Note:How parallel processing works with FME: see关于并行处理有关详细信息。
此参数确定变压器是否应跨行进程执行工作。如果启用了，将为每个组的组启动一个过程Group Byparameter.
并行处理水平
For example, on a quad-core machine, minimal parallelism will result in two simultaneous FME processes. Extreme parallelism on an 8-core machine would result in 16 simultaneous processes.
You can experiment with this feature and view the information in the Windows Task Manager and the Workbench Log window.
输入按组订购
Yes: This transformer will process input groups in order. Changes on the value of theGroup By参数的输入流将触发批量processing on the currently accumulating group. This will improve overall speed if groups are large/complex, but could cause undesired behavior if input groups are not truly ordered.
No: This is the default behavior. Processing will only occur in this transformer once all input is present.
Attributes
累积属性
If this parameter is set toYes，原始功能的属性将合并到输出点云功能上。
计数属性
If you specify a计数属性parameter (text string), an attribute with this name will be added to each output feature.
The attribute contains the number of features that were combined to create the point cloud feature.
Raster Parameters
提取Nodata.
This parameter specifies whether points should be created for nodata cells in rasters. When set toYes，无论是Nodata如何，都将为每个单元格创建一个点。设置到No, points will not be created for nodata cells. A cell is considered to be nodata when, for each selected band, the value for that cell is equal to that band's nodata value. If any cell value is not equal to that band's nodata value, the cell will be considered data.
Vector Feature Interpolation
点间隔
This parameter controls the spacing between points in ground coordinates that will be used to generate the representative point grid used for surfaces, solids, polygons, and donuts. You can either enter a number or extract the value from a selected attribute.
Measures to Preserve as Components
Measures to Preserve as Components
Specifies the measures on input vector geometries that should be preserved as components in the output point cloud. The type of the output component must also be specified.
要保存为组件的属性
要保存为组件的属性
Specifies the attributes on input features that should be preserved as components in the output point cloud. The type of the output component must also be specified. Note that if the same component is specified as both a measure and attribute to preserve, the measure value will be preferred.
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变压器范围Menu Options。
