FME Transformers: 2024.1

Filters and Joins
Spatial Analysis


Creates aggregates of features based on their proximity to each other. Each aggregate that is created covers approximately the neighborhood width and height (measured in feature ground units).

This transformer is used to reduce the data volume of "wallpaper" types of features that have no individual attributes. The resulting aggregates can be output to a system using many fewer records than if each feature was output by itself. For systems that support aggregates, or multi-part features, this can result in substantial performance improvements and greatly decrease storage requirements.




Editing Transformer Parameters

Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.

For more information, see Transformer Parameter Menu Options.
