Hi!
Thank you for your useful indications! It seems that the addon
v.what.rast.buffer is capable of doing what I want. I am trying to
modify it by substituting r.univar -g with r.stats -anl but I get the
following error message:
Calculating stats for cat ...
Sorry, <map> is not a valid parameter
ERROR: Required parameter <input> not set:
(Name of input raster map(s)).
I would greatly appreciate if you give me some suggestions on how me
to solve this problem!
thanks again!
Alessandro
Alessandro,
Some mounth ago I have modified the script to have a report for each
point into a text file. Here the code:
#%option
#% key: prefix_stats
#% type: string
#% gisprompt: new_file,file,output
#% key_desc: name
#% description: Name for output prefix stats data (if omitted or "-"
output to stdout)
#% required: no
#%end
[...]
PREFIX_STATS="$GIS_OPT_PREFIX_STATS"
[...]
if [ -e "$PREFIX_STATS" ] ; then
g.message -e "Output File [$PREFIX_STATS] already exists"
exit 1
fi
[...]
g.message " Calculating stats for cat $ID ..."
echo $ID >> ${PREFIX_STATS}.txt
r.stats -clN in="$MAP" fs="|" >> ${PREFIX_STATS}.txt
eval `r.univar -g map="$MAP"`
Hope can help!
Giovanni
