filters.range¶

The range filter applies rudimentary filtering to the input point cloud based on a set of criteria on the given dimensions.

Pipeline Example¶

This example passes through all points whose Z value is in the range [0,100] and whose classification equals 2 (corresponding to ground in LAS).

<?xml version="1.0" encoding="utf-8"?>
<Pipeline version="1.0">
  <Writer type="writers.las">
    <Option name="filename">
      filtered.las
    </Option>
    <Filter type="filters.range">
      <Option name="limits">
        Z[0:100],Classification[2:2]
      </Option>
      <Reader type="readers.las">
        <Option name="filename">
          input.las
        </Option>
      </Reader>
    </Filter>
  </Writer>
</Pipeline>

Command-line Example¶

The equivalent pipeline invoked via the PDAL translate command would be

$ pdal translate -i input.las -o filtered.las -f range --filters.range.limits="Z[0:100],Classification[2:2]"

Options¶

limits

A comma-separated list of Ranges. If more than one range is specified for a dimension, the criteria are treated as being logically ORed together. Ranges for different dimensions are treated as being logically ANDed.

Example:

Classification[1:2], Red[1:50], Blue[25:75], Red[75:255], Classification[6:7]

This specification will select points that have the classification of 1, 2, 6 or 7 and have a blue value or 25-75 and have a red value of 1-50 or 75-255. In this case, all values are inclusive.
