Hi all,
I've managed to convert a number of coverages from arc7 to grass. It's
work great except that a large number of polygons on each cover don't
get labeled. It get lots of point to area errors. Has anyone run into
this problem and been able to fix it? I dread the thought of having to
fix this by hand... it's several thousand polygons over several coverages.
Another approach is to simply write out the .pat file, after doing "addxy",
and manually process the fields into grass att and cats files, after running
v.in.arc only for the linework. Then support the updated vector coverage.
to manually process the fields to dig_att it do this:
awk '{printf "A %14.6f %14.6f %8d\n", $2, $3, $1}' arcpatfile > $LOCATION/dig_att/newcov
where $1 is the -id and $2 and $3 are the added xy.
Another question is about using photographs. Has anyone tried to use
pictures that they took from a camera and then stretched them onto the
topography? If no one has done this, I'll probably try and write something
that does this in the near future... I have lots of useful pictures that
I took while trudging around my field area.Thanks,
Kurt.
i saw a demo doing this with i.ortho or something like that, but i
couldn't begin to explain it more..
