*DATASET REDUCE SPATIAL POINTS*
===============================

Reduces the number of spatial points in a dataset by down-sampling selected columns, useful for thinning dense spatial data before visualization or further processing. Provide a dataset and specify which columns contain the spatial coordinates or values to be reduced.

When to use
-----------

Classification: **process**.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Dataset
     - dataset_1
     - dataset
     - —
     - 
     - Input dataset to be spatially down-sampled; accepts any tabular dataset — leave unconnected if passing data inline via a preceding node.
   * - Columns
     - columns
     - scalar
     - —
     - 
     - One or more column names from dataset_1 that identify the spatial dimensions or value fields to reduce; select from the dynamic list populated by dataset_1, leave blank to apply reduction across all columns.

Outputs
-------

   * - Label
     - ID
     - Type
     - Description
   * - dataset_rsp_output_1
     - dataset_rsp_output_1
     - dataset
     - Down-sampled output dataset with the same schema as the input but with a reduced number of spatial point rows in the selected columns.
