The OGR Writer will create files of various vector formats as supported by the OGR library. PDAL points are generally stored as point geometries in the output format, though PDAL will create multipoint geometries instead if the multicount option is set to a value greater than 1. Points can be written with a additional measure value (POINTZM) if measure_dim specifies a valid PDAL dimension, and dimensions can be set as feature attributes using the attr_dims option.
By default, the OGR writer will create ESRI shapefiles. The particular OGR
driver can be specified with the
Output file to write. The writer will accept a filename containing a single placeholder character (
#). If input to the writer consists of multiple PointViews, each will be written to a separate file, where the placeholder will be replaced with an incrementing integer. If no placeholder is found, all PointViews provided to the writer are aggregated into a single file for output. Multiple PointViews are usually the result of multiple input files, or using filters.splitter, filters.chipper or filters.divider.
The driver will use the OGR GeoJSON driver if the output filename extension is
.geojson, and the ESRI Shapefile driver if the output filename extension is
.shp. If neither extension is recognized, the filename is taken to represent a directory in which ESRI Shapefiles are written. The driver can be explicitly specified by using the ogrdriver option.
If 1, point features will be written. If greater than 1, specifies the number of points to group into a feature with a multipoint geometry. Not all OGR drivers support multipoint geometries. [Default: 1]
If specified, points will be written with an extra data field, the dimension of which is specified by this option. Not all output formats support measure data. [Default: None]
List of dimensions to write as feature attributes. Separate multiple values with

Z, and any measure_dim are never written as attributes. This option is incompatible with the multicount option. [Default: None]
The OGR driver to use for output. This option overrides any inference made about output drivers from filename.
List of OGR driver-specific layer creation options, formatted as an
OPTION=VALUEstring. Separate multiple values with

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]
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:
