You are here: Collectors > NeighborhoodAggregator


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

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.
