Good Morning,
I'm interested to know if Grass has the capabilities to "go to" a point
on a map that has been specified on the command line ?I have a region, and I want to specify a site with
a specfic lat and lon, make the cursor go to that point and read the pixel
value at that point. Has anyone done this before ?Many Thanks
Jeremy Dunn
A short shell script will do that. Use r.what to query the map and d.points
to display the point querried. Eliminate the parts you don't want from the
following.
show.point.sh easting northing mapname
------------------------------------------
E=$1
N=$2
MAP=$3
d.rast $MAP
echo $E $N | d.points size=4 color=black type=+
echo $E $N | r.what -f in=$MAP
exit 0
