[pdal] pgpointcloud selector filter and max_capacity

[Oscar Martinez Rubi]

Hi,

About the capacity I found out that i need to specify the capacity in 
both writter and chipper.

Still do not know how to select only x,y,z?

I was also trying to use scale_x,y,z but it crashes when inserting the 
patch. Did somebody managed to do this?

My XML looked like this:

<?xml version="1.0" encoding="utf-8"?>
<Pipeline version="1.0">
     <Writer type="writers.pgpointcloud">
         <Option name="connection">
              dbname='pf20' user='oscar'
         </Option>
         <Option name="table">patches</Option>
         <Option name="compression">dimensional</Option>
         <Option name="capacity">3000</Option>
         <Option name="srid">28992</Option>
         <Option name="scale_x">0.01</Option>
         <Option name="scale_y">0.01</Option>
         <Option name="scale_z">0.01</Option>
         <Filter type="filters.chipper">
             <Option name="capacity">3000</Option>
             <Reader type="readers.las">
                 <Option 
name="filename">/home/oscar/ahn_minibench.laz</Option>
                 <Option name="spatialreference">EPSG:28992</Option>
             </Reader>
         </Filter>
     </Writer>
</Pipeline>

Thanks,

O.
