<tt>Hi,<br>
<br>
I tried earlier on this machine and it did not, although I heavily
suspect that our system-wide installation is sorely outdated. I
will open an issue on github to remind myself to make sure it is
capable of doing so, as performance is certainly an area we would
like to improve in LAG.<br>
<br>
I will open an issue now though to remind myself to make that
change, since that seems like a logical thing to do. If there is
any other laslib documentation and tips anywhere then I will be
glad to look through and see if there's any easy changes I can
make to improve performance.<br>
<br>

Hi,<br>
<br>
sweet. so can LAG readily read LAZ files then?<br>
<br>
you can potentially get a lot of speed-up when you load a fenced
area if you use the simple spatial query functionality through
LASindex that LASlib provides. lasreader->inside() functions
instead of doing your own clipping test in line 304 of
LoadWorker.cpp <br>
<br>
if (usearea)<br>
{<br>
if (!vectorTest(fence.getXs(), fence.getYs(), 4,<br>
reader->point.get_x(),
reader->point.get_y()))<br>
{<br>
skip_counter = 0;<br>
continue;<br>
}<br>
<br>
}<br>
<br>
instead you would put a <br>
<br>
reader->inside_rectangle(fence.getXs()[0], fence.getYs()[0],
fence.getXs()[1], fence.getYs()[1]);<br>
<br>
at the beginning of the reader loop and then LASlib will utilize
the spatially indexing LAX files should they be present or not
give you any win otherwise. For the moment you need to dig through
code and LAStools user forum to learn more about LASindex, but I
will present the details at this year's ELMF in Salzburg <br>
<br>
Cheers,<br>

components present except lidarquadtree.<br>
<br>
I'm trying to compile the lidarquadtree, and have encountered
errors.<br>
<br>
configure error for LAG is:<br>
Package requirements (lidarquadtree >=1.2 were not met: no
package<br>
lidarquadtree found.<br>
<br>
So I went to the lidarquadtree directory in the
lidarsf-lag-53d94dd<br>
directory and did ./configure and make.<br>
<br>
Make returned this error:<br>
In file included from src/LidarPoint.cpp:34:0:<br>
src/LidarPoint.h:38:37: fatal error:
laslib/lasdefinitions.hpp: No<br>
such file or directory<br>
compilation terminated.<br>
<br>
I have the lasdefinitions.hpp file in the laslib directory,
but it is<br>
in ../lastools/laslib/inc/lasdefinitions.hpp<br>
<br>
How do I make configure aware of this file's location? I know
I'm<br>
missing something obvious, but I just cant see it.<br>
<br>
Thanks,<br>
Mark<br>
