Example

[
    {
        "type":"readers.las",
        "array_name":"input.las"
    },
    {
        "type":"writers.tiledb",
        "array_name":"output_array"
    }
]

Options

array_name

TileDB array to write to. [Required]

config_file

TileDB configuration file [Optional]

tile_data_capacity

Number of points per tile [Optional]

x_tile_size

Tile size (x) in a Cartesian projection [Optional]

y_tile_size

Tile size (y) in a Cartesian projection [Optional]

z_tile_size

Tile size (z) in a Cartesian projection [Optional]

chunk_size

Point cache size for chunked writes [Optional]

compression

TileDB compression type for attributes, default is None [Optional]

compression_level

TileDB compression level for chosen compression [Optional]

append

stats

filters

JSON array or object of compression filters for either coords or attributes of the form {coords/attributename : {“compression”: name, compression_options: value, …}} [Optional]

By default TileDB will use the following set of compression filters for coordinates and attributes;

{
    "coords":[
        {"compression": "bit-shuffle"},
        {"compression": "gzip", "compression_level": 9}
    ],
    "Intensity":{"compression": "bzip2", "compression_level": 5},
    "ReturnNumber": {"compression": "zstd", "compression_level": 75},
    "NumberOfReturns": {"compression": "zstd", "compression_level": 75},
    "ScanDirectionFlag": {"compression": "bzip2", "compression_level": 5},
    "EdgeOfFlightLine": {"compression": "bzip2", "compression_level": 5},
    "Classification": {"compression": "gzip", "compression_level": 9},
    "ScanAngleRank": {"compression": "bzip2", "compression_level": 5},
    "UserData": {"compression": "gzip", "compression_level": 9},
    "PointSourceId": {"compression": "bzip2"},
    "Red": {"compression": "rle"},
    "Green": {"compression": "rle"},
    "Blue": {"compression": "rle"},
    "GpsTime": [
        {"compression": "bit-shuffle"},
        {"compression": "zstd", "compression_level": 75}
    ]
}
