Dear list,
I have some issues using SPDmetrics with Windows7-64bit system via R.
I managed to make it works only to calculate numreturnsheight using the
Vyrnwy las file from tutorial 6 and failed to have any other metrics.
My XML file and R code are below (this is also working with my own lasfile)
:
Contents of metricsTEST.xml file
<?xml version="1.0" encoding="UTF-8" ?>
<!--
Description:
XML File for execution within SPDLib
This file contains a template for the
metrics XML interface.
-->
<spdlib:metrics xmlns:spdlib="http://www.spdlib.org/xml/";>
<spdlib:metric metric="numreturnsheight" field="NReturnsGt2m"
return="All" class="NotGrd" lowthreshold="5" />
</spdlib:metrics>
initial code for numreturnsheight
spdmetrics --image -f HFA -r 100 -c 100 -m metricsTEST.xml -i
Vyrnwy_OSGB_10m_h.spd -o Vyrnwy_OSGB_1m_metrics.tiff
R adapted code for numreturnsheight
system(paste('spdmetrics', '--image', '-f HFA', '-r 100', '-c 100', '-m
metricsTEST.xml', '-i', "Vyrnwy_OSGB_10m_h.spd", '-o',
"Vyrnwy_OSGB_1m_metrics.tiff"))
R output

spdmetrics - end
However for any other metrics I tried to calculate so far SPDmetrics.exe
crashed without giving any results. I tried to use percentileheight,
mean/maxheight one by one without success.
My XML file and R code are below ( percentileheight).

I would like to know if you can help me with this. Is there anything wrong
within my command line or is this issue specific to windows7/64 systems?
Thanks,
Best regards
Anouk
