# writers.e57

The E57 Writer supports writing to E57 files.

The writer supports E57 files with Cartesian point clouds.

Note

E57 files can contain multiple point clouds stored in a single file. The writer will only write a single cloud per file.

Note

Spherical format points are not supported.

Note

The E57 cartesianInvalidState dimension is mapped to the Omit PDAL dimension. A range filter can be used to filter out the invalid points.

Dynamic Plugin

This stage requires a dynamic plugin to operate

Streamable Stage

This stage supports streaming operations

## Example

    [
        {
            "type":"readers.las",
            "filename":"inputfile.las"
        },
        {
            "type":"writers.e57",
            "filename":"outputfile.e57",
              "doublePrecision":false
        }
    ]

## Options

filename

  E57 file to write [Required]

doublePrecision

  Use double precision for storage (false by default).

where

  An expression that limits points passed to a writer. 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 writer was run. [Default: `auto`]
