I’m developing a pipeline in python which produces the following JSON:<br class="">
<br class="">
> pipeString ='{"pipeline": ["./pgc_input/chug_lidar/<wbr class="">Kenai/Points/Ken_00403.las", {"radius": 46.330202145018255, "type": "filters.crop", "point": "POINT(671977.\<br class="">

<br class="">
<br class="">
PDAL doesn’t seem to understand radius using `filters.crop`:<br class=""></blockquote><div class=""><br class=""></div><div class="">Somehow the docs got out of sync with the code. Not sure how this happened but I will fix. The correct name of the option is "distance" rather than "radius". You can use "pdal --options filters.crop" at the command line to get an up-to-date list of the options for the crop filter.</div><div class=""><br class=""></div><div class="">Hope that helps.</div><div class=""><br class=""></div><div class="">-- <br class=""></div></div><div class="gmail_signature" data-smartmail="gmail_signature">Andrew Bell<br class=""><a href="mailto:andrew.bell.ia@gmail.com" target="_blank" class="">andrew.bell.ia@gmail.com</a></div>
