<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have added in liblas (master branch in github) two new tools that maybe useful for DB users:</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>las2pg: converts a LAS/LAZ into PostgreSQL binary dump format. It can be used for faster flat (1 point per row) data insertion in PostgreSQL. This is useful when you use flat tables for your point clouds (not recommended for large point
clouds) of if you want to create pc_patches in a custom manner (other than what PDAL does). It is the alternative to making the insert with las2txt (essentially binary is faster than ASCII). Example of usage:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">psql -c "create table flat (x double precision, y double precision, z double precision, r integer, g integer, b integer, i integer)"<o:p></o:p></p>
<p class="MsoNormal">las2pg -i 1.2-with-color.laz --parse xyzRGBi --stdout | psql -c "copy flat from stdin with binary"<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>las2col: similarly to las2pg, this tool converts a LAS/LAZ into binary columnar files to be imported in the column-store MonetDB (<a href="https://www.monetdb.org/">https://www.monetdb.org/</a>). Example of usage:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">las2col -i 1.2-with-color.laz -o out --parse XYZi<o:p></o:p></p>
<p class="MsoNormal">mclient <db_name> -s "create table flat (x decimal(8,2), y decimal(8,2), z decimal(8,2), i smallint)"<o:p></o:p></p>
<p class="MsoNormal">mclient <db_name> -s "COPY BINARY INTO flat FROM ('<full_parent_path>/out_col_x.dat','<full_parent_path>/out_col_y.dat','<full_parent_path>/out_col_z.dat','<full_parent_path>/out_col_i.dat')"<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If time permits, we will add similar writers in PDAL, so the same functionality is available through PDAL
