filters.divider¶
The Divider Filter breaks a point view into a set of smaller point views based on simple criteria. The number of subsets can be specified explicitly, or one can specify a maximum point count for each subset. Additionally, points can be placed into each subset sequentially (as they appear in the input) or in round-robin fashion.
Normally points are divided into subsets to facilitate output by writers that support creating multiple output files with a template (LAS and BPF are notable examples).
Example¶
This pipeline will create 10 output files from the input file readers.las.
[
"example.las",
{
"type":"filters.divider",
"count":"10"
},
{
"type":"writers.las",
"filename":"out_#.las"
}
]
Options¶
- mode
A mode of “partition” will write sequential points to an output view until the view meets its predetermined size. “round_robin” mode will iterate through the output views as it writes sequential points. [Default: “partition”]
- count
Number of output views. [Default: none]
- capacity
Maximum number of points in each output view. Views will contain approximately equal numbers of points. [Default: none]
