NAME
i.spectralDESCRIPTION
i.spectral displays spectral response at user specified locations in images.NOTES
This script needs gnuplot to be installed.EXAMPLE
To analyze a time series of maps, run:d.rast map_1
LIST=`g.mlist type=rast mapset=timeseries pat="map_*" | sort -t '_' -k 2 -n | tr '\n' ','| sed 's+,$++g'`
i.spectral -i rast=$LIST
This will search all maps in the mapset 'timeseries' which match have the 'map_' prefix and order by a number following this prefix (day of the year etc). The user is then asked to click into a map position and the resulting pixel values of all matching maps are drawn in the gnuplot output.
