# filters.sort

The sort filter orders a point view based on the values of a dimension. The sorting can be done in increasing (ascending) or decreasing (descending) order.

Default Embedded Stage

This stage is enabled by default

## Example

    [
        "unsorted.las",
        {
            "type":"filters.sort",
            "dimension":"X",
            "order":"ASC"
        },
        "sorted.las"
    ]

## Options

dimension

  The dimension on which to sort the points. [Required]

order

  The order in which to sort, ASC or DESC [Default: “ASC”]

where

  An expression that limits points passed to a filter. Points that don’t pass the expression skip the stage but are available to subsequent stages in a pipeline. [Default: no filtering]

where_merge

  A strategy for merging points skipped by a ‘where’ option when running in standard mode. If `true`, the skipped points are added to the first point view returned by the skipped filter. If `false`, skipped points are placed in their own point view. If `auto`, skipped points are merged into the returned point view provided that only one point view is returned and it has the same point count as it did when the filter was run. [Default: `auto`]
