filters.splitter

The Splitter Filter breaks a point cloud into square tiles of a specified size. The origin of the tiles is chosen arbitrarily unless specified with the origin_x and origin_y option.

The splitter takes a single PointView as its input and creates a PointView for each tile as its output.

Splitting is usually applied to data read from files (which produce one large stream of points) before the points are written to a database (which prefer data segmented into smaller blocks).

Default Embedded Stage

Example

[
    "input.las",
    {
        "type":"filters.splitter",
        "length":"100",
        "origin_x":"638900.0",
        "origin_y":"835500.0"
    },
    {
        "type":"writers.pgpointcloud",
        "connection":"dbname='lidar' user='user'"
    }
]

Options

length
Length of the sides of the tiles that are created to hold points. [Default: 1000]
origin_x
X Origin of the tiles. [Default: none (chosen arbitarily)]
origin_y
Y Origin of the tiles. [Default: none (chosen arbitarily)]
buffer
Amount of overlap to include in each tile. This buffer is added onto length in both the x and the y direction. [Default: 0]
