default_srs

Spatial reference to apply to the data if the input does not specify one. Can be specified as a WKT, proj.4 or EPSG string. Can’t use with ‘override_srs’ [Default: none]

zookeeper_url

table_namespace

The table name to be used when interacting with GeoWave. [Required]

feature_type_name

The feature type name to be used when interacting GeoWave. [Default: PDAL_Point]

data_adapter

FeatureCollectionDataAdapter stores multiple points per Accumulo entry. FeatureDataAdapter stores a single point per Accumulo entry. [Default: FeatureCollectionDataAdapter]

points_per_entry

Sets the maximum number of points per Accumulo entry when using FeatureCollectionDataAdapter. [Default: 5000]

bounds
