[GRASS-user] Python script in grass

[Christian Kaiser]

Ciao,

What you can do, is write your point into a temporary file and then read in again this file using v.in.ascii command. For example something like this:

import grass.script as grass
import os

# For temporary files
import tempfile as pytempfile

# For deleting temp directory
import shutil

# Create temporary directory
tmpdir = pytempfile.mkdtemp()
tmp_vec = tmpdir + '/vec.ascii'

fp = open(tmp_points, 'w')
fp.write('589541.859564|4473239.49338|9999')
fp.close()

# Read in your point
grass.run_command("v.in.ascii", input=tmp_vec, output=outmap, fs='|', skip=0, x=1, y=2, cat=3, columns='x double precision, y double precision, cat int')

# Remove the temporary directory and all the files in it
shutil.rmtree(tmpdir)


Of course, some error checking would be nice...
