s.menu

[Greg Koerper]

Here is a solution for a non-interactive conversion of sites data to raster 
that was recommended by Michael Shapiro [I believe Michael has also placed
source code on moon which provides non-interactive versions of the individual
s.menu options]:

:
# received from shapiro 911202 as sites_to_cell solution
# then modified

USAGE="$0 [-q quadsize] [-t title] sites_list [raster]"

if [ $# -eq 0 -o ${1-""} = "help" ]
then
    echo $USAGE
    echo "  sites_list = name of the input sites list"
    echo "  raster = name of the output raster file (default:  same as sites)"
    echo '  quadsize = size of each site in cells'
    echo '       (default:  "0" == 1 cell, see s.menu)'
    echo '  title = title for raster map'
    echo '       (default:  "created from sites file $sites")'
    exit -1
fi

# continue only if user is executing GRASS 

if [ "$GISRC" = "" ]
    then
        echo "Sorry, you are not running GRASS" >&2
        exit 4
    else
        USERGRASS="$GISDBASE/$LOCATION_NAME/$MAPSET"
fi

# set defaults, then test for user-specified settings

while [ `echo $1 | cut -c1` = "-" ]
do
    case $1 in
        -q) quadsize=$2
            ;;
        -t) title=$2
            ;;
        *)  echo "$1 is not a valid flag"
            exit -1
            ;;
    esac
    shift 2
done

sites=$1
raster=$2

# remove the raster map to be safe
g.remove ${raster:=$sites} >/dev/null

# output sites file to a file in /tmp

tmp=/tmp/$$
rm -f $tmp
s.out.ascii -ad $sites fs='|' > $tmp

# run the program which converts sites to cell
# the command line has unix-path name of sites file
# the input is
#   quadsize
#   name of output raster map
#   title for raster map
echo "converting sites list $sites to raster $raster"
$GISBASE/etc/sites/sites_to_cell $tmp << EOF
${quadsize:=0}
$raster
${title:="created from sites file $sites"}
EOF
status=$?

rm -f $tmp
exit $status
